Stay in the loop…

Follow the Tweets.

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.

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 -eo rss,vsz,pid,cputime,cmd --width 100 --sort rss,vsz | tail --lines 10
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

watch --differences -n 2 'ps aux | sort -r -nk +4 | head'

Comment by unixmonkey611 297 weeks and 2 days ago

whats wrong with

ps -auxw --sort rss

Comment by eneville 296 weeks and 3 days ago

ps aux | sort -nrk 4 | head

displays the same but in reverse order.

Comment by Roman 296 weeks and 1 day ago

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

Comment by felix001 274 weeks and 1 day ago

@felix001:

ps aux | sort -nrk 3 | head
Comment by pstadler 262 weeks and 1 day ago

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

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