hey , i have to write a script to run a process through shell script and if the process runs successfully then return success.

i used nohup to start the process but nothing occured .

#!/bin/sh
nohup ./cvt -f MediationSources.xml &

can anyone pls help me

Thanks

You could try something like:

Code:

nohup ./cvt -f MediationSources.xml &
c_pid=$!
wait $c_pid
c_status=$?
echo "Exit status is: $c_status"

$! & $? are special shell variables:

Code:

$!            the process id of the last command run in the background.
$?            the exit status of the last command executed.

hey , i used the code but it is not working . is there any way without using nohup. because using nohup

nohup: appending output to `nohup.out' is coming on command line for a long time then i have to stop it using control z.

It may look like it's waiting when it actually isn't, because it's printed overtop your prompt... That can happen with nohup's warning message when you put it in the background, since nohup and shell don't wait for each other with &. Just hit enter and see if your prompt reappears. If it does, then it was in the background already and didn't need killing or stopping.
