LS(1)LS(1)NAMEls - list contents of directory
SYNOPSISls [ -acdfgilqrstu1ACLFR ] name ...
DESCRIPTION
For each directory argument, ls lists the contents of the directory;
for each file argument, ls repeats its name and any other information
requested. By default, the output is sorted alphabetically. When no
argument is given, the current directory is listed. When several
arguments are given, the arguments are first sorted appropriately, but
file arguments are processed before directories and their contents.
There are a large number of options:
-l List in long format, giving mode, number of links, owner, size
in bytes, and time of last modification for each file. If the
file is a special file the size field will instead contain the
major and minor device numbers. If the file is a symbolic link
the pathname of the linked-to file is printed preceded by
``->''.
-g Include the group ownership of the file in a long output.
-t Sort by time modified (latest first) instead of by name.
-a List all entries; in the absence of this option, entries whose
names begin with a period (.) are not listed.
-A List all entries except for the current directory (.) and the
parent directory (..).
-s Give size in kilobytes of each file.
-d If argument is a directory, list only its name; often used with
-l to get the status of a directory.
-L If argument is a symbolic link, list the file or directory the
link references rather than the link itself. Note that if the
link references a directory the link is always followed, unless
the -l option is used.
-r Reverse the order of sort to get reverse alphabetic or oldest
first as appropriate.
-u Use time of last access instead of last modification for sorting
(with the -t option) and/or printing (with the -l option).
-c Use time of last inode-change for sorting (with the -t option)
and/or printing (with the -l option).
-i For each file, print the i-number in the first column of the
report.
-f Force each argument to be interpreted as a directory and list
the name found in each slot. This option turns off -l, -t, -s,
and -r, and turns on -a; the order is the order in which entries
appear in the directory.
-F Cause directories to be marked with a trailing `/', sockets with
a trailing `=', executable files with a trailing `*', and
symbolic links to files with a trailing `@'. Symbolic links to
directories are marked with a trailing `/', unless the -l option
is also used.
-R recursively list subdirectories encountered.
-1 force one entry per line output format; this is the default when
output is not to a terminal.
-C force multi-column output; this is the default when output is to
a terminal.
-q force printing of non-graphic characters in file names as the
character `?'; this is the default when output is to a terminal.
The mode printed under the -l option contains 11 characters which are
interpreted as follows: the first character is
d if the entry is a directory;
b if the entry is a block-type special file;
c if the entry is a character-type special file;
l if the entry is a symbolic link;
s if the entry is a socket, or
- if the entry is a plain file.
The next 9 characters are interpreted as three sets of three bits each.
The first set refers to owner permissions; the next refers to
permissions to others in the same user-group; and the last to all
others. Within each set the three characters indicate permission
respectively to read, to write, or to execute the file as a program.
For a directory, `execute' permission is interpreted to mean permission
to search the directory. The permissions are indicated as follows:
r if the file is readable;
w if the file is writable;
x if the file is executable;
- if the indicated permission is not granted.
The group-execute permission character is given as s if the file has
the set-group-id bit set; likewise the user-execute permission
character is given as s if the file has the set-user-id bit set.
The last character of the mode (normally `x' or `-') is t if the 1000
bit of the mode is on. See chmod(1) for the meaning of this mode.
When the sizes of the files in a directory are listed, a total count of
blocks, including indirect blocks is printed.
FILES
/etc/passwd to get user id's for `ls -l' if NetInfo is not running.
/etc/group to get group id's for `ls -g' if NetInfo is not running.
SEE ALSOnetinfo(5)BUGS
Newline and tab are considered printing characters in file names.
The output device is assumed to be 80 columns wide.
The option setting based on whether the output is a teletype is
undesirable as ``ls -s'' is much different than ``ls -s | lpr''. On
the other hand, not doing this setting would make old shell scripts
which used ls almost certain losers.
