Script to clone a repository

#!/usr/bin/env bash

REPONAME=${TARGET##*/}
echo "`date +"%d.%m.%Y %H:%M:%S"` --- Start processing repository $REPONAME"

git clone --bare ${SOURCE}
pushd ./${REPONAME}
git remote add myclone ${TARGET}

git fetch --tags
git push --all myclone
git push --tags myclone

Allow to clone an existing repository

# If you need to use http
# git config --global credential.helper cache

# Ensure to use already cached credential helper
git config credential.helper store

# Well a git clone is better !
git fetch --verbose --prune ; git pull --rebase

git remote add d4k https://<HOST_NAME>/<GROUP_NAME>/<REPOSITORY_NAME>.git
git push d4k --all ; git push d4k --tags

Using option --mirror

To push all your branches, use either (replace REMOTE with the name of the remote, for example "origin"):

git push REMOTE '*:*'
git push REMOTE --all

To push all your tags:

git push REMOTE --tags

Finally, I think you can do this all in one command with:

git push REMOTE --mirror

However, in addition --mirror, will also push your remotes, so this might not be exactly what you want.
