Find the process you are looking for minus the grepped one

Terminal - Find the process you are looking for minus the grepped one
ps -C command

Find the process you are looking for minus the grepped one

preferred way to query ps for a specific process name (not supported with all flavors of ps, but will work on just about any linux afaik)


There are 4 alternatives - vote for the best!

Terminal - Alternatives
ps aux | grep [p]rocess-name
2009-08-13 05:44:45
User: olorin
Functions: grep ps

As an alternative to using an additional grep -v grep you can use a simple regular expression in the search pattern (first letter is something out of the single letter list ;-)) to drop the grep command itself.

ps axu | grep [a]pache2
2012-12-15 19:37:19
User: EBAH
Functions: grep ps

Trick to avoid the form:

grep process | grep - v grep

pgrep command_name
ps -ef | grep c\\ommand
2011-01-04 11:43:14
User: ioggstream
Functions: grep ps
Tags: grep ps

faster ;) but your idea is really cool

ps -ef | awk '/process-name/ && !/awk/ {print}'
2009-08-19 11:22:09
User: dopeman
Functions: awk ps

This does the same thing as many of the 'grep' based alternatives but allows a more finite control over the output. For example if you only wanted the process ID you could change the command:

ps -ef | awk '/mingetty/ && !/awk/ {print $2}'

If you wanted to kill the returned PID's:

ps -ef | awk '/mingetty/ && !/awk/ {print $2}' | xargs -i kill {}

Know a better way?

If you can do better, submit your command here.

What others think

Nice one, but only works on command names, not on parameters (which happens sometimes to be interesting ;-))
