pslurp: parallel process kill program
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 behaves 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 connections.
- -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 backslashes.
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 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 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).
