Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

Perhaps a use of killall instead?

or pkill?

Comment by sander85 395 weeks and 6 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 395 weeks and 4 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}'
