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
