WGET(1) GNU Wget WGET(1)NAMEwget - GNU Wget Manual
SYNOPSISwget [option]... [URL]...
DESCRIPTION
GNU Wget is a freely available network utility to retrieve files from
the World Wide Web, using HTTP (Hyper Text Transfer Protocol) and FTP
(File Transfer Protocol), the two most widely used Internet protocols.
It has many useful features to make downloading easier, some of them
being:
· Wget is non-interactive, meaning that it can work in the
background, while the user is not logged on. This allows you to
start a retrieval and disconnect from the system, letting Wget
finish the work. By contrast, most of the Web browsers require
constant user's presence, which can be a great hindrance when
transferring a lot of data.
· Wget is capable of descending recursively through the structure of
HTML documents and FTP directory trees, making a local copy of the
directory hierarchy similar to the one on the remote server. This
feature can be used to mirror archives and home pages, or traverse
the web in search of data, like a WWW robot. In that spirit, Wget
understands the norobots convention.
· File name wildcard matching and recursive mirroring of directories
are available when retrieving via FTP. Wget can read the time-
stamp information given by both HTTP and FTP servers, and store it
locally. Thus Wget can see if the remote file has changed since
last retrieval, and automatically retrieve the new version if it
has. This makes Wget suitable for mirroring of FTP sites, as well
as home pages.
· Wget works exceedingly well on slow or unstable connections,
retrying the document until it is fully retrieved, or until a user-
specified retry count is surpassed. It will try to resume the
download from the point of interruption, using REST with FTP and
Range with HTTP servers that support them.
· By default, Wget supports proxy servers, which can lighten the
network load, speed up retrieval and provide access behind
firewalls. However, if you are behind a firewall that requires
that you use a socks style gateway, you can get the socks library
and build Wget with support for socks. Wget also supports the
passive FTP downloading as an option.
· Builtin features offer mechanisms to tune which links you wish to
follow.
· The retrieval is conveniently traced with printing dots, each dot
representing a fixed amount of data received (1KB by default).
These representations can be customized to your preferences.
· Most of the features are fully configurable, either through command
line options, or via the initialization file .wgetrc. Wget allows
you to define global startup files (/usr/local/etc/wgetrc by
default) for site settings.
· Finally, GNU Wget is free software. This means that everyone may
use it, redistribute it and/or modify it under the terms of the GNU
General Public License, as published by the Free Software
Foundation.
OPTIONS
Basic Startup Options
-V
--version
Display the version of Wget.
-h
--help
Print a help message describing all of Wget's command-line options.
-b
--background
Go to background immediately after startup. If no output file is
specified via the -o, output is redirected to wget-log.
-e command
--execute command
Execute command as if it were a part of .wgetrc. A command thus
invoked will be executed after the commands in .wgetrc, thus taking
precedence over them.
Logging and Input File Options
-o logfile
--output-file=logfile
Log all messages to logfile. The messages are normally reported to
standard error.
-a logfile
--append-output=logfile
Append to logfile. This is the same as -o, only it appends to
logfile instead of overwriting the old log file. If logfile does
not exist, a new file is created.
-d
--debug
Turn on debug output, meaning various information important to the
developers of Wget if it does not work properly. Your system
administrator may have chosen to compile Wget without debug
support, in which case -d will not work. Please note that
compiling with debug support is always safe---Wget compiled with
the debug support will not print any debug info unless requested
with -d.
-q
--quiet
Turn off Wget's output.
-v
--verbose
Turn on verbose output, with all the available data. The default
output is verbose.
-nv
--non-verbose
Non-verbose output---turn off verbose without being completely
quiet (use -q for that), which means that error messages and basic
information still get printed.
-i file
--input-file=file
Read URLs from file, in which case no URLs need to be on the
command line. If there are URLs both on the command line and in an
input file, those on the command lines will be the first ones to be
retrieved. The file need not be an HTML document (but no harm if
it is)---it is enough if the URLs are just listed sequentially.
However, if you specify --force-html, the document will be regarded
as html. In that case you may have problems with relative links,
which you can solve either by adding <base href="url"> to the
documents or by specifying --base=url on the command line.
-F
--force-html
When input is read from a file, force it to be treated as an HTML
file. This enables you to retrieve relative links from existing
HTML files on your local disk, by adding <base href="url"> to HTML,
or using the --base command-line option.
-B URL
--base=URL
When used in conjunction with -F, prepends URL to relative links in
the file specified by -i.
Download Options
--bind-address=ADDRESS
When making client TCP/IP connections, bind() to ADDRESS on the
local machine. ADDRESS may be specified as a hostname or IP
address. This option can be useful if your machine is bound to
multiple IPs.
-t number
--tries=number
Set number of retries to number. Specify 0 or inf for infinite
retrying.
-O file
--output-document=file
The documents will not be written to the appropriate files, but all
will be concatenated together and written to file. If file already
exists, it will be overwritten. If the file is -, the documents
will be written to standard output. Including this option
automatically sets the number of tries to 1.
-nc
--no-clobber
If a file is downloaded more than once in the same directory,
Wget's behavior depends on a few options, including -nc. In
certain cases, the local file will be clobbered, or overwritten,
upon repeated download. In other cases it will be preserved.
When running Wget without -N, -nc, or -r, downloading the same file
in the same directory will result in the original copy of file
being preserved and the second copy being named file.1. If that
file is downloaded yet again, the third copy will be named file.2,
and so on. When -nc is specified, this behavior is suppressed, and
Wget will refuse to download newer copies of file. Therefore,
``no-clobber'' is actually a misnomer in this mode---it's not
clobbering that's prevented (as the numeric suffixes were already
preventing clobbering), but rather the multiple version saving
that's prevented.
When running Wget with -r, but without -N or -nc, re-downloading a
file will result in the new copy simply overwriting the old.
Adding -nc will prevent this behavior, instead causing the original
version to be preserved and any newer copies on the server to be
ignored.
When running Wget with -N, with or without -r, the decision as to
whether or not to download a newer copy of a file depends on the
local and remote timestamp and size of the file. -nc may not be
specified at the same time as -N.
Note that when -nc is specified, files with the suffixes .html or
(yuck) .htm will be loaded from the local disk and parsed as if
they had been retrieved from the Web.
-c
--continue
Continue getting a partially-downloaded file. This is useful when
you want to finish up a download started by a previous instance of
Wget, or by another program. For instance:
wget-c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z
If there is a file named ls-lR.Z in the current directory, Wget
will assume that it is the first portion of the remote file, and
will ask the server to continue the retrieval from an offset equal
to the length of the local file.
Note that you don't need to specify this option if you just want
the current invocation of Wget to retry downloading a file should
the connection be lost midway through. This is the default
behavior. -c only affects resumption of downloads started prior to
this invocation of Wget, and whose local files are still sitting
around.
Without -c, the previous example would just download the remote
file to ls-lR.Z.1, leaving the truncated ls-lR.Z file alone.
Beginning with Wget 1.7, if you use -c on a non-empty file, and it
turns out that the server does not support continued downloading,
Wget will refuse to start the download from scratch, which would
effectively ruin existing contents. If you really want the
download to start from scratch, remove the file.
Also beginning with Wget 1.7, if you use -c on a file which is of
equal size as the one on the server, Wget will refuse to download
the file and print an explanatory message. The same happens when
the file is smaller on the server than locally (presumably because
it was changed on the server since your last download
attempt)---because ``continuing'' is not meaningful, no download
occurs.
On the other side of the coin, while using -c, any file that's
bigger on the server than locally will be considered an incomplete
download and only (length(remote) - length(local)) bytes will be
downloaded and tacked onto the end of the local file. This
behavior can be desirable in certain cases---for instance, you can
use wget-c to download just the new portion that's been appended
to a data collection or log file.
However, if the file is bigger on the server because it's been
changed, as opposed to just appended to, you'll end up with a
garbled file. Wget has no way of verifying that the local file is
really a valid prefix of the remote file. You need to be
especially careful of this when using -c in conjunction with -r,
since every file will be considered as an "incomplete download"
candidate.
Another instance where you'll get a garbled file if you try to use
-c is if you have a lame HTTP proxy that inserts a ``transfer
interrupted'' string into the local file. In the future a
``rollback'' option may be added to deal with this case.
Note that -c only works with FTP servers and with HTTP servers that
support the Range header.
--dot-style=style
Set the retrieval style to style. Wget traces the retrieval of
each document by printing dots on the screen, each dot representing
a fixed amount of retrieved data. Any number of dots may be
separated in a cluster, to make counting easier. This option
allows you to choose one of the pre-defined styles, determining the
number of bytes represented by a dot, the number of dots in a
cluster, and the number of dots on the line.
With the default style each dot represents 1K, there are ten dots
in a cluster and 50 dots in a line. The binary style has a more
``computer''-like orientation---8K dots, 16-dots clusters and 48
dots per line (which makes for 384K lines). The mega style is
suitable for downloading very large files---each dot represents 64K
retrieved, there are eight dots in a cluster, and 48 dots on each
line (so each line contains 3M). The micro style is exactly the
reverse; it is suitable for downloading small files, with 128-byte
dots, 8 dots per cluster, and 48 dots (6K) per line.
-N
--timestamping
Turn on time-stamping.
-S
--server-response
Print the headers sent by HTTP servers and responses sent by FTP
servers.
--spider
When invoked with this option, Wget will behave as a Web spider,
which means that it will not download the pages, just check that
they are there. You can use it to check your bookmarks, e.g. with:
wget--spider --force-html -i bookmarks.html
This feature needs much more work for Wget to get close to the
functionality of real WWW spiders.
-T seconds
--timeout=seconds
Set the read timeout to seconds seconds. Whenever a network read
is issued, the file descriptor is checked for a timeout, which
could otherwise leave a pending connection (uninterrupted read).
The default timeout is 900 seconds (fifteen minutes). Setting
timeout to 0 will disable checking for timeouts.
Please do not lower the default timeout value with this option
unless you know what you are doing.
-w seconds
--wait=seconds
Wait the specified number of seconds between the retrievals. Use
of this option is recommended, as it lightens the server load by
making the requests less frequent. Instead of in seconds, the time
can be specified in minutes using the m suffix, in hours using h
suffix, or in days using d suffix.
Specifying a large value for this option is useful if the network
or the destination host is down, so that Wget can wait long enough
to reasonably expect the network error to be fixed before the
retry.
--waitretry=seconds
If you don't want Wget to wait between every retrieval, but only
between retries of failed downloads, you can use this option. Wget
will use linear backoff, waiting 1 second after the first failure
on a given file, then waiting 2 seconds after the second failure on
that file, up to the maximum number of seconds you specify.
Therefore, a value of 10 will actually make Wget wait up to (1 + 2
+ ... + 10) = 55 seconds per file.
Note that this option is turned on by default in the global wgetrc
file.
-Y on/off
--proxy=on/off
Turn proxy support on or off. The proxy is on by default if the
appropriate environmental variable is defined.
-Q quota
--quota=quota
Specify download quota for automatic retrievals. The value can be
specified in bytes (default), kilobytes (with k suffix), or
megabytes (with m suffix).
Note that quota will never affect downloading a single file. So if
you specify wget-Q10k ftp://wuarchive.wustl.edu/ls-lR.gz, all of
the ls-lR.gz will be downloaded. The same goes even when several
URLs are specified on the command-line. However, quota is
respected when retrieving either recursively, or from an input
file. Thus you may safely type wget-Q2m -i sites---download will
be aborted when the quota is exceeded.
Setting quota to 0 or to inf unlimits the download quota.
Directory Options
-nd
--no-directories
Do not create a hierarchy of directories when retrieving
recursively. With this option turned on, all files will get saved
to the current directory, without clobbering (if a name shows up
more than once, the filenames will get extensions .n).
-x
--force-directories
The opposite of -nd---create a hierarchy of directories, even if
one would not have been created otherwise. E.g. wget-x
http://fly.srk.fer.hr/robots.txt will save the downloaded file to
fly.srk.fer.hr/robots.txt.
-nH
--no-host-directories
Disable generation of host-prefixed directories. By default,
invoking Wget with -r http://fly.srk.fer.hr/ will create a
structure of directories beginning with fly.srk.fer.hr/. This
option disables such behavior.
--cut-dirs=number
Ignore number directory components. This is useful for getting a
fine-grained control over the directory where recursive retrieval
will be saved.
Take, for example, the directory at
ftp://ftp.xemacs.org/pub/xemacs/. If you retrieve it with -r, it
will be saved locally under ftp.xemacs.org/pub/xemacs/. While the
-nH option can remove the ftp.xemacs.org/ part, you are still stuck
with pub/xemacs. This is where --cut-dirs comes in handy; it makes
Wget not ``see'' number remote directory components. Here are
several examples of how --cut-dirs option works.
No options -> ftp.xemacs.org/pub/xemacs/
-nH -> pub/xemacs/
-nH --cut-dirs=1 -> xemacs/
-nH --cut-dirs=2 -> .
--cut-dirs=1 -> ftp.xemacs.org/xemacs/
...
If you just want to get rid of the directory structure, this option
is similar to a combination of -nd and -P. However, unlike -nd,
--cut-dirs does not lose with subdirectories---for instance, with
-nH --cut-dirs=1, a beta/ subdirectory will be placed to
xemacs/beta, as one would expect.
-P prefix
--directory-prefix=prefix
Set directory prefix to prefix. The directory prefix is the
directory where all other files and subdirectories will be saved
to, i.e. the top of the retrieval tree. The default is . (the
current directory).
HTTP Options
-E
--html-extension
If a file of type text/html is downloaded and the URL does not end
with the regexp \.[Hh][Tt][Mm][Ll]?, this option will cause the
suffix .html to be appended to the local filename. This is useful,
for instance, when you're mirroring a remote site that uses .asp
pages, but you want the mirrored pages to be viewable on your stock
Apache server. Another good use for this is when you're
downloading the output of CGIs. A URL like
http://site.com/article.cgi?25 will be saved as
article.cgi?25.html.
Note that filenames changed in this way will be re-downloaded every
time you re-mirror a site, because Wget can't tell that the local
X.html file corresponds to remote URL X (since it doesn't yet know
that the URL produces output of type text/html. To prevent this
re-downloading, you must use -k and -K so that the original version
of the file will be saved as X.orig.
--http-user=user
--http-passwd=password
Specify the username user and password password on an HTTP server.
According to the type of the challenge, Wget will encode them using
either the basic (insecure) or the digest authentication scheme.
Another way to specify username and password is in the URL itself.
For more information about security issues with Wget,
-C on/off
--cache=on/off
When set to off, disable server-side cache. In this case, Wget
will send the remote server an appropriate directive (Pragma: no-
cache) to get the file from the remote service, rather than
returning the cached version. This is especially useful for
retrieving and flushing out-of-date documents on proxy servers.
Caching is allowed by default.
--cookies=on/off
When set to off, disable the use of cookies. Cookies are a
mechanism for maintaining server-side state. The server sends the
client a cookie using the Set-Cookie header, and the client
responds with the same cookie upon further requests. Since cookies
allow the server owners to keep track of visitors and for sites to
exchange this information, some consider them a breach of privacy.
The default is to use cookies; however, storing cookies is not on
by default.
--load-cookies file
Load cookies from file before the first HTTP retrieval. The format
of file is one used by Netscape and Mozilla, at least their Unix
version.
--save-cookies file
Save cookies from file at the end of session. Cookies whose expiry
time is not specified, or those that have already expired, are not
saved.
--ignore-length
Unfortunately, some HTTP servers (CGI programs, to be more precise)
send out bogus Content-Length headers, which makes Wget go wild, as
it thinks not all the document was retrieved. You can spot this
syndrome if Wget retries getting the same document again and again,
each time claiming that the (otherwise normal) connection has
closed on the very same byte.
With this option, Wget will ignore the Content-Length header---as
if it never existed.
--header=additional-header
Define an additional-header to be passed to the HTTP servers.
Headers must contain a : preceded by one or more non-blank
characters, and must not contain newlines.
You may define more than one additional header by specifying
--header more than once.
wget --header='Accept-Charset: iso-8859-2' \
--header='Accept-Language: hr' \
http://fly.srk.fer.hr/
Specification of an empty string as the header value will clear all
previous user-defined headers.
--proxy-user=user
--proxy-passwd=password
Specify the username user and password password for authentication
on a proxy server. Wget will encode them using the basic
authentication scheme.
--referer=url
Include `Referer: url' header in HTTP request. Useful for
retrieving documents with server-side processing that assume they
are always being retrieved by interactive web browsers and only
come out properly when Referer is set to one of the pages that
point to them.
-s
--save-headers
Save the headers sent by the HTTP server to the file, preceding the
actual contents, with an empty line as the separator.
-U agent-string
--user-agent=agent-string
Identify as agent-string to the HTTP server.
The HTTP protocol allows the clients to identify themselves using a
User-Agent header field. This enables distinguishing the WWW
software, usually for statistical purposes or for tracing of
protocol violations. Wget normally identifies as Wget/version,
version being the current version number of Wget.
However, some sites have been known to impose the policy of
tailoring the output according to the User-Agent-supplied
information. While conceptually this is not such a bad idea, it
has been abused by servers denying information to clients other
than Mozilla or Microsoft Internet Explorer. This option allows
you to change the User-Agent line issued by Wget. Use of this
option is discouraged, unless you really know what you are doing.
FTP Options
-nr
--dont-remove-listing
Don't remove the temporary .listing files generated by FTP
retrievals. Normally, these files contain the raw directory
listings received from FTP servers. Not removing them can be
useful for debugging purposes, or when you want to be able to
easily check on the contents of remote server directories (e.g. to
verify that a mirror you're running is complete).
Note that even though Wget writes to a known filename for this
file, this is not a security hole in the scenario of a user making
.listing a symbolic link to /etc/passwd or something and asking
root to run Wget in his or her directory. Depending on the options
used, either Wget will refuse to write to .listing, making the
globbing/recursion/time-stamping operation fail, or the symbolic
link will be deleted and replaced with the actual .listing file, or
the listing will be written to a .listing.number file.
Even though this situation isn't a problem, though, root should
never run Wget in a non-trusted user's directory. A user could do
something as simple as linking index.html to /etc/passwd and asking
root to run Wget with -N or -r so the file will be overwritten.
-g on/off
--glob=on/off
Turn FTP globbing on or off. Globbing means you may use the shell-
like special characters (wildcards), like *, ?, [ and ] to retrieve
more than one file from the same directory at once, like:
wget ftp://gnjilux.srk.fer.hr/*.msg
By default, globbing will be turned on if the URL contains a
globbing character. This option may be used to turn globbing on or
off permanently.
You may have to quote the URL to protect it from being expanded by
your shell. Globbing makes Wget look for a directory listing,
which is system-specific. This is why it currently works only with
Unix FTP servers (and the ones emulating Unix ls output).
--passive-ftp
Use the passive FTP retrieval scheme, in which the client initiates
the data connection. This is sometimes required for FTP to work
behind firewalls.
--retr-symlinks
Usually, when retrieving FTP directories recursively and a symbolic
link is encountered, the linked-to file is not downloaded.
Instead, a matching symbolic link is created on the local
filesystem. The pointed-to file will not be downloaded unless this
recursive retrieval would have encountered it separately and
downloaded it anyway.
When --retr-symlinks is specified, however, symbolic links are
traversed and the pointed-to files are retrieved. At this time,
this option does not cause Wget to traverse symlinks to directories
and recurse through them, but in the future it should be enhanced
to do this.
Note that when retrieving a file (not a directory) because it was
specified on the commandline, rather than because it was recursed
to, this option has no effect. Symbolic links are always traversed
in this case.
Recursive Retrieval Options
-r
--recursive
Turn on recursive retrieving.
-l depth
--level=depth
Specify recursion maximum depth level depth. The default maximum
depth is 5.
--delete-after
This option tells Wget to delete every single file it downloads,
after having done so. It is useful for pre-fetching popular pages
through a proxy, e.g.:
wget-r -nd --delete-after http://whatever.com/~popular/page/
The -r option is to retrieve recursively, and -nd to not create
directories.
Note that --delete-after deletes files on the local machine. It
does not issue the DELE command to remote FTP sites, for instance.
Also note that when --delete-after is specified, --convert-links is
ignored, so .orig files are simply not created in the first place.
-k
--convert-links
After the download is complete, convert the links in the document
to make them suitable for local viewing. This affects not only the
visible hyperlinks, but any part of the document that links to
external content, such as embedded images, links to style sheets,
hyperlinks to non-HTML content, etc.
Each link will be changed in one of the two ways:
· The links to files that have been downloaded by Wget will be
changed to refer to the file they point to as a relative link.
Example: if the downloaded file /foo/doc.html links to
/bar/img.gif, also downloaded, then the link in doc.html will
be modified to point to ../bar/img.gif. This kind of
transformation works reliably for arbitrary combinations of
directories.
· The links to files that have not been downloaded by Wget will
be changed to include host name and absolute path of the
location they point to.
Example: if the downloaded file /foo/doc.html links to
/bar/img.gif (or to ../bar/img.gif), then the link in doc.html
will be modified to point to http://hostname/bar/img.gif.
Because of this, local browsing works reliably: if a linked
file was downloaded, the link will refer to its local name; if
it was not downloaded, the link will refer to its full Internet
address rather than presenting a broken link. The fact that
the former links are converted to relative links ensures that
you can move the downloaded hierarchy to another directory.
Note that only at the end of the download can Wget know which
links have been downloaded. Because of that, the work done by
-k will be performed at the end of all the downloads.
-K
--backup-converted
When converting a file, back up the original version with a .orig
suffix. Affects the behavior of -N.
-m
--mirror
Turn on options suitable for mirroring. This option turns on
recursion and time-stamping, sets infinite recursion depth and
keeps FTP directory listings. It is currently equivalent to -r -N
-l inf -nr.
-p
--page-requisites
This option causes Wget to download all the files that are
necessary to properly display a given HTML page. This includes
such things as inlined images, sounds, and referenced stylesheets.
Ordinarily, when downloading a single HTML page, any requisite
documents that may be needed to display it properly are not
downloaded. Using -r together with -l can help, but since Wget
does not ordinarily distinguish between external and inlined
documents, one is generally left with ``leaf documents'' that are
missing their requisites.
For instance, say document 1.html contains an <IMG> tag referencing
1.gif and an <A> tag pointing to external document 2.html. Say
that 2.html is similar but that its image is 2.gif and it links to
3.html. Say this continues up to some arbitrarily high number.
If one executes the command:
wget-r -l 2 http://I<site>/1.html
then 1.html, 1.gif, 2.html, 2.gif, and 3.html will be downloaded.
As you can see, 3.html is without its requisite 3.gif because Wget
is simply counting the number of hops (up to 2) away from 1.html in
order to determine where to stop the recursion. However, with this
command:
wget-r -l 2 -p http://I<site>/1.html
all the above files and 3.html's requisite 3.gif will be
downloaded. Similarly,
wget-r -l 1 -p http://I<site>/1.html
will cause 1.html, 1.gif, 2.html, and 2.gif to be downloaded. One
might think that:
wget-r -l 0 -p http://I<site>/1.html
would download just 1.html and 1.gif, but unfortunately this is not
the case, because -l 0 is equivalent to -l inf---that is, infinite
recursion. To download a single HTML page (or a handful of them,
all specified on the commandline or in a -i URL input file) and its
(or their) requisites, simply leave off -r and -l:
wget-p http://I<site>/1.html
Note that Wget will behave as if -r had been specified, but only
that single page and its requisites will be downloaded. Links from
that page to external documents will not be followed. Actually, to
download a single page and all its requisites (even if they exist
on separate websites), and make sure the lot displays properly
locally, this author likes to use a few options in addition to -p:
wget-E -H -k -K -nh -p http://I<site>/I<document>
In one case you'll need to add a couple more options. If document
is a <FRAMESET> page, the "one more hop" that -p gives you won't be
enough---you'll get the <FRAME> pages that are referenced, but you
won't get their requisites. Therefore, in this case you'll need to
add -r -l1 to the commandline. The -r -l1 will recurse from the
<FRAMESET> page to to the <FRAME> pages, and the -p will get their
requisites. If you're already using a recursion level of 1 or
more, you'll need to up it by one. In the future, -p may be made
smarter so that it'll do "two more hops" in the case of a
<FRAMESET> page.
To finish off this topic, it's worth knowing that Wget's idea of an
external document link is any URL specified in an <A> tag, an
<AREA> tag, or a <LINK> tag other than <LINK REL="stylesheet">.
Recursive Accept/Reject Options
-A acclist --accept acclist
-R rejlist --reject rejlist
Specify comma-separated lists of file name suffixes or patterns to
accept or reject.
-D domain-list
--domains=domain-list
Set domains to be accepted and DNS looked-up, where domain-list is
a comma-separated list. Note that it does not turn on -H. This
option speeds things up, even if only one host is spanned.
--exclude-domains domain-list
Exclude the domains given in a comma-separated domain-list from
DNS-lookup.
--follow-ftp
Follow FTP links from HTML documents. Without this option, Wget
will ignore all the FTP links.
--follow-tags=list
Wget has an internal table of HTML tag / attribute pairs that it
considers when looking for linked documents during a recursive
retrieval. If a user wants only a subset of those tags to be
considered, however, he or she should be specify such tags in a
comma-separated list with this option.
-G list
--ignore-tags=list
This is the opposite of the --follow-tags option. To skip certain
HTML tags when recursively looking for documents to download,
specify them in a comma-separated list.
In the past, the -G option was the best bet for downloading a
single page and its requisites, using a commandline like:
wget-Ga,area -H -k -K -nh -r http://I<site>/I<document>
However, the author of this option came across a page with tags
like <LINK REL="home" HREF="/"> and came to the realization that -G
was not enough. One can't just tell Wget to ignore <LINK>, because
then stylesheets will not be downloaded. Now the best bet for
downloading a single page and its requisites is the dedicated
--page-requisites option.
-H
--span-hosts
Enable spanning across hosts when doing recursive retrieving.
-L
--relative
Follow relative links only. Useful for retrieving a specific home
page without any distractions, not even those from the same hosts.
-I list
--include-directories=list
Specify a comma-separated list of directories you wish to follow
when downloading Elements of list may contain wildcards.
-X list
--exclude-directories=list
Specify a comma-separated list of directories you wish to exclude
from download Elements of list may contain wildcards.
-nh
--no-host-lookup
Disable the time-consuming DNS lookup of almost all hosts.
-np
--no-parent
Do not ever ascend to the parent directory when retrieving
recursively. This is a useful option, since it guarantees that
only the files below a certain hierarchy will be downloaded.
FILES
/usr/local/etc/wgetrc
Default location of the global startup file.
.wgetrc
User startup file.
BUGS
You are welcome to send bug reports about GNU Wget to <bug-
wget@gnu.org>.
Before actually submitting a bug report, please try to follow a few
simple guidelines.
1. Please try to ascertain that the behaviour you see really is a bug.
If Wget crashes, it's a bug. If Wget does not behave as
documented, it's a bug. If things work strange, but you are not
sure about the way they are supposed to work, it might well be a
bug.
2. Try to repeat the bug in as simple circumstances as possible. E.g.
if Wget crashes on wget-rLl0 -t5 -Y0 http://yoyodyne.com -o
/tmp/log, you should try to see if it will crash with a simpler set
of options.
Also, while I will probably be interested to know the contents of
your .wgetrc file, just dumping it into the debug message is
probably a bad idea. Instead, you should first try to see if the
bug repeats with .wgetrc moved out of the way. Only if it turns
out that .wgetrc settings affect the bug, should you mail me the
relevant parts of the file.
3. Please start Wget with -d option and send the log (or the relevant
parts of it). If Wget was compiled without debug support,
recompile it. It is much easier to trace bugs with debug support
on.
4. If Wget has crashed, try to run it in a debugger, e.g. gdb `which
wget` core and type where to get the backtrace.
5. Find where the bug is, fix it and send me the patches. :-)
