Stop bash script without command line

Question

I've got a problem, which I cannot solve on my own.

I want to start a bash script on bamboo, so I cannot stop it with ^C. This bash script starts a server, which should run after stopping the script.

If I start the script with the command line, it works as it should, but in order to stop the script I either have to enter Enter or ^C to exit the script. But I cannot do this in Bamboo!

This is a short version of my script:

#!/bin/bash
./Server &

I start it with: /bin/bash ./executeServer.sh &

At the end of the script I tried to write:

exit 0 -> no consequence

kill %1 -> the script stops before starting the server

^C -> unknown command

Thank you!!

I think it is a little bit overcomplicated. Actually you do not need to start bash as it is started when You start ./executeServer.sh. Add executable rights to ./executeServer.sh and start it as it is. And do not need to start it in the background, as it already starts Server in the background in the script.

Thanks for this hint! This works fine, but doesn't solve my problem. – tralala Jun 06 '13 at 08:25
@IsaMunich: Sorry, which script you are talking about? I assume it is the `./executeServer.sh`. It stops automatically, after starting `./Server`. You do not need to stop! So if it is not stopping, then the problem is not in this snipplet. – TrueY Jun 06 '13 at 08:35
But why doesn't Bamboo stop? I have to quit this task on my own and then there is "Build was not successfull" but it executes my script as it should... If I start it via the command line, I also have to enter `Enter` to be able to enter a new command. – tralala Jun 06 '13 at 08:39
@IsaMunich: Ok. What happen if You just start an empty `bash` script (only having the `#!/bin/bash` line from your script)? Is it stopping properly? – TrueY Jun 06 '13 at 08:44
No, unfortunately not. But now I got a hint from a friend of mine: If I enter `nohup ./executeServer.sh` it works! Thank you!!! (Also see: http://stackoverflow.com/questions/8122780/exiting-shell-script-with-background-processes) – tralala Jun 06 '13 at 08:58
@IsaMunich: `nohup` just redirects `stdin` to `/dev/null`, `stdout` to `nohup.out` and `stderr` to `stdin` (so to the `nohup.out` file). Maybe the `stdin` caused the problem in your case. – TrueY Jun 06 '13 at 09:33

If I enter nohup ./executeServer.sh it works!
