return background process id

[rayshi2001]

How can I save the PID of a background process when it is started in shell script?

Note that redirect >err or >>err don't work.

you can get the PID of the background process using $! shell variable
e.g
lp Myfile &
Pid=$!
wait $Pid

will wait for the print job to finish, the pid will be in $Pid
