Suspending a process

Evelyn Daroga — Wed, 12 Dec 2001 15:23:22 GMT

Is there any way to suspend an actively executing process? It is a user process; we do not want to kill it, just put it on "hold" until we can determine what it has done.

z will stop a process, not kill it. Then you can run fg and it will start the processes again

something else, if its not run from your terminal, you can run kill -24 PID to pasue,
then kill -26 PID to continue

Yep, you can send it a SIGSTOP:

$ kill -STOP

And to get it running again, SIGCONT:

$ kill -CONT

hey,

Use 'kill -24 pid' to pause a process.

then 'kill -26 pid' to continue.

see man kill for more information

Do a kill -24 pid on the process to stop. kill -26 pid will resume it.

HI
You can use the kill command to stop the process.
Here are details on signames

24 SIGSTOP Stop Pause the process; cannot be trapped.
25 SIGTSTP Terminal stop Pause the process; can be trapped
26 SIGCONT Continue Run a stopped process

Thanks.
Prashant.

If you are at the command line and have run your process in your current shell Jeffs method will work great. However, if the process is running outside of your shell then use the kill -24 command on the PID to pause the process. Then use the kill -26 command on the PID to resume a paused process. Check out the man page on kill. It also has some good examples at the end.
