NAME
       pslurp -- parallel process kill program

SYNOPSIS
       pslurp  [-vAr]  [-h  hosts_file]	 [-H [user@]host[:port]] [-l user] [-p
       par] [-o	outdir]	[-e errdir] [-t	timeout] [-O options]  [-x  args]  [-X
       arg] [-L	localdir] remote local

DESCRIPTION
       pslurp  is  a  program  for  copying files in parallel from a number of
       hosts.  It provides features such as passing a password to scp,	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  pslurp  be-
	      haves  as	 though	 these files were concatenated together.  If a
	      host is specified	multiple times,	then pslurp 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, pslurp	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 SSH command-line arguments (see the ssh(1) man page
	      for more information about SSH arguments).  This option  may  be
	      specified	 multiple times.  The arguments	are processed to split
	      on whitespace, protect text within quotes, and escape with back-
	      slashes.	 To pass arguments without such	processing, use	the -X
	      option instead.

       -X arg
       --extra-arg arg
	      Passes a single SSH command-line argument	(see  the  ssh(1)  man
	      page  for	 more information about	SSH 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.

       -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 op-
	      tion 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 ssh with the -i and \	options.

       -r
       --recursive
	      Recursively copy directories.

       -L localdir
       --localdir localdir
	      Copy files from the remote host to the given local directory.

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 pslurp 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 scp process reported
	      an error (exit status other than 0).
