I want to see list of process created by specific user or group of user in Linux Can I do it using ps command or is there any other command to achieve this?

    ps -u username. Most commands have a manual page which you can read with man the-command. – Stéphane Chazelas Aug 4 '13 at 9:03

To view only the processes owned by a specific user, use the following command:

top -U [username]

Replace the [username] with the required username

If you want to use ps then

ps -u [username]


 ps -ef | grep <username>


ps -efl | grep <username>

for the extended listing

Check out the man ps page for options

Another alternative is to use pstree wchich prints the process tree of the user

pstree <username or pid>

    All ` ... | grep <username>` solutions don't work if you have two usernames which are longer than N chars. In my case N is 6. – guettli Jan 19 '18 at 10:44

    Note: I got an error for top -U [username], and top -u [username] worked for me instead. Debian 9. So if anybody else gets an error with the -U form, try the lowercase. – Gloweye Oct 29 '18 at 9:08

try this one

ps -fp $(pgrep -u <username>)

  • How is this better than ps -u <username>, as mentioned in the existing answer (or ps -fu <username> if you want process details)? – Stephen Kitt Jan 23 '18 at 8:27
  • ps -u doesn't provide full process details, but ps -fu <username> does. Agree ps -fu is a best solution – user939407 Jan 24 '18 at 10:03
