Setting up and maintaining Git repository mirrors

mirrors.sh

#!/bin/bash

## This shell script will read all names from repos.txt
## which are names of git repositories located at 
## git@main-reposerver:/path/to/repos
## if a mirror is not created, it will create
## 
## other wise it will try to update the mirror
## 
## Main purpose of having mirrors is backup so pushing 
## changes to main repo is disabled by default. To enable
## it, uncomment the two lines below

for repo in `cat repos.txt`
do
    rdir="/home/git/mirrors/$repo"
    if [ -d $rdir ]; then
        echo "Mirror for $repo found.."
	echo "Fetching updates from main repo.."
	`cd $repo && git remote update`
	# echo "Pushing updates to main repo"
	# `cd $repo && git push --mirror`
    else
        echo "Mirror for $repo not found.."
	echo "Creating a mirror.."
	`git clone --mirror git@main-reposerver:/path/to/repos/$repo`
    fi
