Post Commit Hook Not Running

Question

My post commit hook is not running after git. I have verified that the hook does work if I just run it from the terminal. The code in the hook is:

#!/bin/sh
#.git/hooks/post-commit
# An example hook script that is called after a successful
# commit is made.
#
# To enable this hook, rename this file to "post-commit".

perl -pi -e 's/([a-f0-9]+)$/'$( git rev-parse HEAD )/ ../../config/commit.git

I did rename the file to post-commit in ./.git/hooks/ and the permissions are -rwxr-x-r-x so I am not sure why it doesn't work.

I'll leave this here as an answer because I stumbled upon my own answer for when my post-commit hook wasn't running:

chmod +x .git/hooks/post-commit

Probably applies to any kind of hook. In fact, probably applies to any kind of script.

This is exactly the issue I was having. Thanks for including it as an answer. – jbranchaud Mar 06 '13 at 05:35
Oh those pesky permissions. Exact problem I was having too. Thx. :) – arxpoetica May 23 '13 at 17:14
Missed that too. Thanks! – andershqst May 27 '14 at 19:56

what if you have permissions 777 and hook still not running? post-checkout runs , but post-receive not, when it is exactly same commands. It should run on git pull. – Dariux Jan 06 '15 at 07:16
@Darius.V maybe it needs to actually receive something rather than "Already up-to-date."? Just a thought. – Steven Lu Feb 01 '17 at 21:55

Try putting some echo lines before and after the perl line like this:

echo "post-commit started"
perl ...........
echo "post-commit finished"

This way you can confirm if the script is actually running, because when you run

git commit

you should see

post-commit started
post-commit finished

Towards the end of your output.

thanks. The post-commit was running, but it did have an error. The path should have been ./ rather than ../../. – Dave Long Feb 22 '11 at 21:45
Steven Lu's permissions answer bit should be added to this accepted answer. – mlg Nov 03 '19 at 22:54

My post-commit script wasn't being called because:

I had named the script post-commit.sh, rather than just post-commit.

To enable a hook script, put a file in the hooks subdirectory of your .git directory that is named appropriately (without any extension) and is executable. From that point forward, it should be called. We’ll cover most of the major hook filenames here. See git-scm

Not sure why I had in my head that hooks needed the bash file extension.

I also didn't realize hook scripts cannot have file extensions. For example,

If you want to use the bundled hook scripts, you’ll have to rename them; their file names all end with .sample

Hope this helps someone.

I also missed that part of the instructions; I just saw `but any properly named executable scripts will work fine` and dropped in pre-commit.sh. Ended up on this question, saw the most popular answer, and thought "yeah, I already did that". Then I noticed your answer. Thanks! – Ickster Feb 19 '17 at 15:42

This is a good answer! As far as I can tell in UNIX-land, file extensions aren't much of a thing. It's simply a convention that Windows has embraced. Much of the confusion related to this could be traced to Windows' default behavior of hiding those extensions, which, even on Windows, are very much a crucial portion of the file's name and path. – Steven Lu Mar 29 '18 at 21:42

In addition to the answers noted here, note that if you are expecting user input in your hook, you need to redirect standard input to the keyboard like so (at least for a bash script);

exec < /dev/tty
