Simple shell script to update all git repositories in a directory. Requires the `lockfile` utility from Procmail.

gitpull

#!/bin/sh

# Updates git repositories

LOCKFILE=/tmp/git.lock

lockfile -r 0 $LOCKFILE || exit 1

GIT=`which git`

for i in `ls`; do
    echo $i
    cd $i
    if [[ -e .git ]]; then
        git fetch --all --prune
        git pull
    fi
    cd -
done

rm -f $LOCKFILE
