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:

       •   PSSH_HOSTS
       •   PSSH_USER
       •   PSSH_PAR
       •   PSSH_OUTDIR
       •   PSSH_VERBOSE
       •   PSSH_OPTIONS
