PARALLEL-NUKE(1)														  PARALLEL-NUKE(1)

NAME
       parallel-nuke - kill a bunch of processes on a set of machines

SYNOPSIS
       parallel-nuke [OPTIONS] -h hosts.txt pattern

DESCRIPTION
       pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
       homogenously-configured hosts.

       The parallel-nuke command is useful when you want to kill a bunch of processes on a set of machines.

OPTIONS
       -h --hosts
	   hosts file (each line "host[:port] [user]")

       -l --user
	   username (OPTIONAL)

       -p --par
	   max number of parallel threads (OPTIONAL)

       -o --outdir
	   output directory for stdout files (OPTIONAL)

       -e --errdir
	   output directory for stderr files (OPTIONAL)

       -t --timeout
	   timeout (secs) (-1 = no timeout) per host (OPTIONAL)

       -O --options
	   SSH options (OPTIONAL)

       -v --verbose
	   turn on warning and diagnostic messages (OPTIONAL)

EXAMPLE
       For example, suppose you've got a bunch of java processes running on three nodes that you'd like to nuke (let's use the three machines from
       the pssh example). Here you would do the following:

	   # parallel-nuke -h ips.txt -l irb2 java
	   Success on 128.112.152.122:22
	   Success on 18.31.0.190:22
	   Success on 128.232.103.201:22

ENVIRONMENT
       All four programs take similar sets of options. All of these options can be set using the following environment variables:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
       o   PSSH_OUTDIR
       o   PSSH_VERBOSE
       o   PSSH_OPTIONS
