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

show top 10 most memory hungry process with a simple format of (%mem, pid, short command)

show top 10 most memory hungry process with a simple format of (%mem, pid, short command)

Pros: the format is very simple, there is no need to show every columns, and full command with args

the first column is memory consumption %

the second column is pid

the third is just the command (without full arguments, most application's arguments are too long)

You can decide which application to kill then.


There are 3 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

A couple of problems.

First, there's a typo. The command uses 'ppid' (parent process id), when you mean 'pid'.

Next, you have "head -11 | tail -10". This is ugly and wrong.

You've just sorted the list, so the header won't be at the top.

head and tail give you lines 2-11 which means I've lost the first entry: the most memory hungry.

If you're using the procps version of ps, you can turn off the headers:

ps -eo pmem,pid,comm --no-headers | sort -k 1 -r -n | head

ps is capable of sorting its output, but I can't get a working example.
