Display the top ten running processes - sorted by memory usage

ps returns all running processes which are then sorted by the 4th field in numerical order and the top 10 are sent to STDOUT.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
ps aux --sort -rss | head
ps axo %mem,pid,euser,cmd | sort -nr | head -n 10

What others think

The +n option is considered deprecated - a more up-to-date version of this command would be:

ps aux | sort -b -k 4 | tail

Comment by unixmonkey611 341 weeks and 1 day ago

ps -auxw --sort rss

Comment by eneville 340 weeks and 2 days ago

ps aux | sort -nrk 4 | head

displays the same but in reverse order.

Whats the best way to output the highest usage by CPU ?

Comment by felix001 318 weeks ago

@felix001:

ps aux | sort -nrk 3 | head
Comment by pstadler 306 weeks ago

More useful output - I just want memory usage and full command line:

ps -e -orss=,args= | sort -b -k1,1n | pr -TW$COLUMNS
