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

ps -eo pmem,pid,comm --no-headers | sort -k1 -rn | head -10
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.

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.
