Sort all processes by the amount of virtual memory they are using

ps -e -o pid,vsz,comm= | sort -n -k 2
left-most column is PID, middle is virtual memory being consumed, right-most is actual process.

  • This is a alternate command I like to use instead of TOP or HTOP to see what are the processes which are taking up the most memory on a system. It shows the username, process ID, CPU usage, Memory usage, thread ID, Number of threads associated with parent process, Resident Set Size, Virtual Memory Size, start time of the process, and command arguments. Then it's sorted by memory and showing the top 10 with head. This of course can be changed to suit you needs. I have a small system which is why Firefox is taking so much resources.

  • you can also pipe it to "tail" command to show 10 most memory using processes. Show Sample Output

    ps aux --sort=%mem,%cpu

  • This command will show the 20 processes using the most CPU time (hungriest at the bottom). You can see the 20 most memory intensive processes (hungriest at the bottom) by running: ps aux | sort +3n | tail -20 Or, run both: echo "CPU:" && ps aux | sort +2n | tail -20 && echo "Memory:" && ps aux | sort +3n | tail -20

    ps aux | sort +2n | tail -20
