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

Use ps instead of top. But do not use BSD options at all, they are confusing.

Use "s=" or "state=" to show consice process statuses.

The other 2 commands that are listed will also kill the egrep process and any libexec processes because the .exe isn't escaped so it is really using . meaning anything containing exe. The command i posted escapes the (dot) in .exe and then filters the actual egrep process so that it doesn't get killed before the other processes being killed. Also added the -9 switch for kill to send sigterm to the processes, in case people are wondering why processes aren't getting killed after running just kill . This should work better for people :)

Use it as bash-script.

The first positional parameter specifies the fixed length of the numerical index.

Further params specify the files to manipulate.
