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.


There is 1 alternative - 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
