Question
When using the ps -x command to check the status of a process in Linux, how would you know if a process is suspended (stopped)?
Solution
When you run the ps -x command in Linux, it will display the status of the current processes. The status of each process is shown in the "STAT" column.
If a process is suspended or stopped, it will be indicated by a "T" in the STAT column.
Here are the possible states:
- D: Uninterruptible sleep (usually IO)
- R: Running or runnable (on run queue)
- S: Interruptible sleep (waiting for an event to complete)
- T: Stopped, either by a job control signal or because it is being traced.
- W: Paging (not valid since the 2.6.xx kernel)
- X: Dead (should never be seen)
- Z: Defunct ("zombie") process, terminated but not reaped by its parent.
So, to check if a process is suspended, you would look for a "T" in the STAT column of the output from the ps -x command.
