NAME
       prsync -- parallel process kill program

SYNOPSIS
       prsync  [-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

DESCRIPTION
       prsync 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).
