What others think

Perhaps a use of killall instead?

or pkill?

Comment by sander85 313 weeks and 4 days ago

and please don't use kill -9, this is very bad behaviour. Please try it with kill -15 and if it doesn't end the process kill -2. Then you can still use kill -9.

Wow. grep piped to grep piped to awk. Never thought I'd see that.

Comment by atoponce 313 weeks and 3 days ago

Apart from the fact that there's pkill and killall (depending on the OS), there are quite a lot of things that can be improved in this command line.

First, this is a nice trick to avoid the ugly "grep -v grep" part:

ps ax | grep '[p]rocessname'

Note that the first letter is enclosed in square brackets. This regular expression will match 'processname', but it will not match the grep command itself.

Second, it doesn't make sense to pipe from grep to awk because awk has a "built-in grep":

ps ax | awk '/[p]rocessname/{print $1}'
