parallel-rsync is a program for copying files in parallel to a number of hosts using  the  popular  rsync
       program.  It provides features such as passing a password to ssh, saving output to files, and timing out.

       The exit status codes from parallel-rsync 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).

-hhost_file--hostshost_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 parallel-rsync behaves as though these files
              were concatenated together.  If a host is  specified  multiple  times,  then  parallel-rsync  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.

       -luser--useruser
              Use the given username as the default for any host entries that don't specifically specify a user.

       -pparallelism--parparallelism
              Use the given number as the maximum number of concurrent connections.

       -ttimeout--timeouttimeout
              Make  connections  time  out after the given number of seconds.  With a value of 0, parallel-rsync
              will not timeout any connections.

       -ooutdir--outdiroutdir
              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.

       -eerrdir--errdirerrdir
              Save  standard  error to files in the given directory.  Filenames are of the same form as with the
              -o option.

       -xargs--extra-argsargs
              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.

       -Xarg--extra-argarg
              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 arguments, use the option once for each argument.

       -Ooptions--optionsoptions
              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 password.

       -v--verbose
              Include error messages from rsync with the -i and -e options.

       -r--recursive
              Recursively copy directories.

       -a--archive
              Use rsync archive mode (rsync's -a option).

       -z--compress
              Use rsync compression.

       -Sargs--ssh-argsargs
              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
              processing.

       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 parallel-ssh host files,  provides  a
       tremendous amount of flexibility.
