What Are the Process States in Unix/Linux?
When the process is not waiting for any resource and ready to be executed by the CPU, it will be in the RUNNABLE state.
On the other hand, if the process is in the UNINTERRUPTABLE_SLEEP state, then the issuing a SIGKILL signal will not terminate it immediately.
In Linux, when you issue the ‘Ctrl + Z’ command it will issue a SIGSTOP signal to the process.
When a process is in the STOPPED state, it will only handle SIGKILL and SIGCONT signals.
