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

A simple but effective replacement for ps aux. I used to waste my time running ps over and over; top is the way to go. It also allows complex sorting options. Press q to exit "nicely" (Ctrl + C is always an option, of course). Note that the list updates each second, resorting in the process; if you're trying to grab a specific PID, you might be better off with ps.


Alternatively, htop is available, though it may not come pre-installed. htop is slightly more interactive than top and includes color coding, visuals, and a nice interface for selecting and then killing processes. (Thanks to bwoodacre for this great tool.)

What others think

top is good. These days (under linux) I like htop more.

Top has a nifty bunch of commands.

Type "?" to see the list.

"c" toggles command / command line (fu++ :-)

I love that alternative, bwoodacre; I just yum'd it. I'm going to edit it into the description. I doubt I'll ever type "top" again. ;)

Comment by Zenexer 423 weeks and 4 days ago

Try htop also.

Comment by waltharius 423 weeks and 4 days ago

waltharius: Yes, that's listed as an alternative. Many Linux systems do not have htop/vtop installed by default, however.

Comment by Zenexer 423 weeks and 4 days ago

Top doesn't always cut it for me. I find myself using 'ps' and 'pstree' a lot (with various options that depend on what I'm looking for. If I'm in Slackware, I sometimes use 'socklist'...a similar command in the BSD world is 'sockstat'.
