How can I monitor the thread count of a process on linux?

Question

I would like to monitor the number of threads used by a specific process on Linux. Is there an easy way to get this information without impacting the performance of the proc

Answer 1

If you want the number of threads per user in a linux system then you should use:

ps -eLf | grep  | awk '{ num += $6 } END { print num }'

where as use the desired user name.
