NAME
parallel-nuke - kill a bunch of processes on a set of machinesSYNOPSIS
parallel-nuke [OPTIONS] -h hosts.txt patternDESCRIPTION
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
