commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):
Subscribe to the feed for:
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 4 alternatives - vote for the best!

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 | headps is capable of sorting its output, but I can't get a working example.
Updated according to flatcap's comments.
Thanks very much :-)
