exiting shell script with background processes


From memory a login shell will be kept around even when it finishes if any of its still running children have standard (terminal) file handles open. Normal (sub process) shells do not seem to suffer from this. So see if changing your nohup line to the following makes any difference.

nohup myInScript.sh >some.log 2>&1 </dev/null &

On Centos5 I do not get the problem if I run parent.sh. But I do if I run ssh localhost parent.sh. In this case the I/O redirection I showed above solves the problem.


The solution above works most of the time:

nohup myInScript.sh >some.log 2>&1 </dev/null &

But I've had a case where it didn't, not sure why. Anyway the at command did the trick and even looks more classy:

at now -f my_script.sh
