Individual thread priority checking using command line in linux

Question

I can see number of threads used in application by going to /proc/$(pidof task)/ and giving

cat status.

Is there any way to check individual thread priority in linux using commands?

Answer 1

Run ps with-m -l. It will list all the thread and priority with respect to particular PID

ps -m -l [PID]

Example:

PC@PCuser:~$ ps -m -l 10070

F S   UID   PID  PPID  C PRI  NI ADDR SZ WCHAN  TTY        TIME CMD
0 -  1000 10070     1  0   -   - - 31325 -      ?          0:42 gedit
0 S  1000     -     -  0  80   0 -     - poll_s -          0:41 -
1 S  1000     -     -  0  80   0 -     - poll_s -          0:00 -
1 S  1000     -     -  0  80   0 -     - poll_s -          0:00 -

EDIT:

PC@PCuser:~$ ps -T -l [PID]

F S   UID   PID  SPID  PPID  C PRI  NI ADDR SZ WCHAN  TTY        TIME CMD
0 S  1000 10070 10070     1  0  80   0 - 31325 poll_s ?          0:42 gedit
1 S  1000 10070 10073     1  0  80   0 - 31325 poll_s ?          0:00 gedit
1 S  1000 10070 10074     1  0  80   0 - 31325 poll_s ?          0:00 gedit

I prefer ps -T -l [PID] – Vocation

Yes you are correct. It will give some more information. I will update my answer – Theophany

What is the priority range? Higher number means higher priority? – Vulgarism

Answer 2

$ ps -T -l [PID] can give me more information, but it can't provide the thread name on my system. I combine this result and (gdb) info thread to get more details.

Answer 3

ps -T -l -p [PID] This command gives me the thread priority info with the thread names
