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