Git remote/shared pre-commit hook

Question

With a one official repository as the remote, and multiple local repositories cloned from it, can a pre-commit hook be scripted on that main repository and be enforced on al

Answer 1

You can not have the pre-commit hook forced on peoples local repositories, but in your central repo you can still run a pre-receive hook.

F. ex I needed to be sure the commit messages obeyed certain rules (for trac integration etc) so I used following pre-receive hook, which checks every commit messages being pushed to the central repository, and will deny the push if it is not welformed.

#!/bin/sh
while read rev_old rev_new ref
do
    MALFORMED="$(git rev-list --oneline $rev_old..$rev_new | egrep -v '#[0-9]+' |  awk '{print $1}' )"
    if [ x"$MALFORMED" != x ]
    then
        echo Invallid commit message on $MALFORMED
        exit 1
    fi
done
