parallel-nuke
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
