SYNOPSISprsync [-vAraz] [-h hosts_file] [-H [user@]host[:port]] [-l user] [-p
par] [-o outdir] [-e errdir] [-t timeout] [-O options] [-x args] [-X
arg] [-S args] local remote
DESCRIPTIONprsync is a program for copying files in parallel to a number of hosts.
It provides features such as passing a password to ssh, saving output
to files, and timing out.
OPTIONS-h host_file
--hosts host_file
Read hosts from the given host_file. Lines in the host file are
of the form [user@]host[:port] and can include blank lines and
comments (lines beginning with "#"). If multiple host files are
given (the -h option is used more than once), then prsync
behaves as though these files were concatenated together. If a
host is specified multiple times, then prsync will connect the
given number of times.
-H [user@]host[:port]
--host [user@]host[:port]
-H "[user@]host[:port] [ [user@]host[:port ] ... ]"
--host "[user@]host[:port] [ [user@]host[:port ] ... ]"
Add the given host strings to the list of hosts. This option
may be given multiple times, and may be used in conjunction with
the -h option.
-l user
--user user
Use the given username as the default for any host entries that
don't specifically specify a user.
-p parallelism
--par parallelism
Use the given number as the maximum number of concurrent connec‐
tions.
-t timeout
--timeout timeout
Make connections time out after the given number of seconds.
With a value of 0, prsync will not timeout any connections.
-o outdir
--outdir outdir
Save standard output to files in the given directory. Filenames
are of the form [user@]host[:port][.num] where the user and port
are only included for hosts that explicitly specify them. The
number is a counter that is incremented each time for hosts that
are specified more than once.
-e errdir
--errdir errdir
Save standard error to files in the given directory. Filenames
are of the same form as with the -o option.
-x args
--extra-args args
Passes extra rsync command-line arguments (see the rsync(1) man
page for more information about rsync arguments). This option
may be specified multiple times. The arguments are processed to
split on whitespace, protect text within quotes, and escape with
backslashes. To pass arguments without such processing, use the
-X option instead.
-X arg
--extra-arg arg
Passes a single rsync command-line argument (see the rsync(1)
man page for more information about rsync arguments). Unlike
the -x option, no processing is performed on the argument,
including word splitting. To pass multiple command-line argu‐
ments, use the option once for each argument.
-O options
--options options
SSH options in the format used in the SSH configuration file
(see the ssh_config(5) man page for more information). This
option may be specified multiple times.
-A
--askpass
Prompt for a password and pass it to ssh. The password may be
used for either to unlock a key or for password authentication.
The password is transferred in a fairly secure manner (e.g., it
will not show up in argument lists). However, be aware that a
root user on your system could potentially intercept the pass‐
word.
-v
--verbose
Include error messages from rsync with the -i and \ options.
-r
--recursive
Recursively copy directories.
-a
--archive
Use rsync archive mode (rsync's -a option).
-z
--compress
Use rsync compression.
-S args
--ssh-args args
Passes extra SSH command-line arguments (see the ssh(1) man page
for more information about SSH arguments). The given value is
appended to the ssh command (rsync's -e option) without any pro‐
cessing.
TIPS
The ssh_config file can include an arbitrary number of Host sections.
Each host entry specifies ssh options which apply only to the given
host. Host definitions can even behave like aliases if the HostName
option is included. This ssh feature, in combination with pssh host
files, provides a tremendous amount of flexibility.
EXIT STATUS
The exit status codes from prsync are as follows:
0 Success
1 Miscellaneous error
2 Syntax or usage error
3 At least one process was killed by a signal or timed out.
4 All processes completed, but at least one rsync process reported
an error (exit status other than 0).
