How can I display the threads per process using ps command?
- To add to the above comment. You can use this command to find the number of threads: find /proc//task -maxdepth 1 -type d -print | wc -l . Just replace the with your process ID that you can get from top or using ps.
- @Navigatron: A simple ls /proc//task | wc will do nicely. – EvertW. Nov 17 ’20 at 9:08.
What is LWP ps?
LWP gives the thread id of each thread. NLWP is the number of threads in the system for the underlying process. In the ps output above, rsyslogd (pid 852) has 4 threads, NetworkManager (pid 874) has three threads and polkitd (pid 893) has two threads.
How do you view threads?
To view the threads in a process with Process Explorer, select a process and open the process properties (double-click on the process or click on the Process, Properties menu item). Then click on the Threads tab. This tab shows a list of the threads in the process and three columns of information.
What is process thread count?

What is process and threads?
A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread.
Can a LWP show the thread level of a process?
They share their address space and system resources with other LWPs within the same process. Command-line tools such as ps or top, display only process level information by default, but they can be instructed to display thread-level information.
How can I see the thread level of a process?
Command-line tools such as ps or top, display only process level information by default, but they can be instructed to display thread-level information. Use either the “-T” or “-L” option of ps to display the threads of a process.
What does the LWP stand for in Linux?
Linux has these nice little processes called LWP (Light Weight Process) or otherwise known as threads. Generally these are spawned by 1 master process that will show up in your normal ps output.
Why are there so many threads in PS?
If you run ps with a -T you will see all of the threads as well. As you can see the process count jumped significantly due to threads. Normally this is never any type of problem, However sometimes a process (usually java based) will have a thread leak.
