Question

I have a script, that I need to run after committing to a project under git revision control. Therefore I created a post-commit hook in my projects .git directory in the subdirectory /hooks, named it ‘post-commit’ and gave it the following contents:

#!/bin/sh
# I am a post-commit hook
/usr/local/bin/my_script &

my_script is executable and runs fine in /bin/sh. In fact it has a runtime of several seconds, so I want it to be backgrounded and detached from the current shell. That’s why I put the trailing ‘&’ to my hook.

The problem now is, that the ‘&’ seems to be ignored. When I commit using gitx 0.7.1 under OSX Lion, gitx hangs for exactly the period that my_script needs to run.

I tried a lot, but do not get the process itself into the background.

What is wrong here?

Here’s how it works for me:

#!/bin/sh
# I am a post-commit hook
nohup /usr/local/bin/my_script &>/dev/null &
