run command in background

Jan 19, 2012 at 10:47 AM


I am trying to do the following. Run a shell script that set some variables, and after that runs another script (a service) in the background.

My code is:

=== ===
var1 = x
./ &

=== ===
while (true); do
    echo "service running"

The problem is that RunCommand() doesn't ends until i kill "". Why? I run "" with RunCommand(), and that scripts end normally. The "" is detachend from it and sent to background.

Please help!
Regards Peter.

Sorry that you nobody reply to this problem yet. I personally not a UNIX person so dont really know what might be a problem.

All RunCommand does is passing the command to the default shell for execution, waits for it to finish and then exits.


I guess what you can try to do is to execute command asynchronously and see if helps you.

Could it be that is still writing output to the shell, so RunCommand continues to listen until the shell is closed?

To test this theory, try something like this:



var1 = x
./ > /dev/null &

Thanks for the help guys!

The asynchronous execution solved the problem. I don't understand why, becouse if I do the same with a normal ssh client (eg. putty), then the script ends normally and I can close the shell too.

The redirect to /dev/null dosen't works. Even if the "" dosen't writes to the console output, the connection still hangs.

Thank again!
Regards Peter.
