Stay in the loop…

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.

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.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives

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.
