Building notes, projects, and occasional rants

Tip: show process sorted by RSS

Several times I needed a way to quickly see which process are using the most memory on a Linux system. After reading a bit of the man page and with a tip from the Apache performance article I was reading, I settled for this:

ps ax -yl --sort:rss  (BSD syntax)
ps -eyl --sort:rss     (standard syntax)

There you go.

Update: corrected the command, thanks to Daniel Fonseca. I messed up BSD syntax (which I prefer) with standard syntax. I included both versions.

Thanks Daniel.

Update: To clarify, this is in a Linux system. On my Mac, the better I was able to do with standard ps command was:

ps alwxm

Not as good, specially because the results are sorted in descending order.
