Executing two commands in parallel
Hi,
I am stuck into a situation where i want to execute a command in my shell script well along with a previous command in order to achieve something but i am not figuring out a way.
here is a snippet:

Code:
service management restart
rm -rf lock.file

in the above, if you see, i am trying to restart a service first.
What happens is that as soon as that command of restart starts running, there is a temporary lock file created.
However, that lock file is causing some performance issues (the restart takes a long time because of the lock file).
Now, i want to override this event by deleting the lock file as soon as the restart command runs.

so, i am looking for way where i can delete the file as soon as the restart command starts running, which i am sure will solve my problem

Is there any way where i can run both commands in parallel (executing both commands together)
Please can any one guide me on this ?
