The number of processes a user is running using bash

Question

Hi, I would like to know how I could get the number of processes for each user that is currently logged in. Thank you.

Answer 1

You could try some variation of this:

ps haux Ou | cut '-d ' -f1 | uniq -c

It gives you the number of processes for each users (being logged in or not). Now you could filter those results using the output of the w command or another way of determining who is logged in.

Answer 2

"ps -u aboelnour | awk 'END {print NR}'"
will show number of process which user aboelnour running it

Answer 3

Following links contain useful ps commands options including your requirements:

• Displaying all processes owned by a specific user
• Show All Running Processes in Linux

Answer 4

userlist=$(w|awk 'BEGIN{ORS=","}NR>2{print $1}'|sed 's/,$//' )
ps -u "$userlist"

Answer 5

Give this a try:

ps -u "$(echo $(w -h | cut -d ' ' -f1 | sort -u))" o user= | sort | uniq -c | sort -rn
