Git export from BitBucket

One of the consequences of moving to git is that I needed to get our deployment scripts working with it. The first requirement was an equivalent to svn export. This is simple enough, but, as usual, I wanted to save myself some effort and created a script that wrapped it up for me.

git-export.sh:

#!/bin/sh

#
# USAGE: export.sh REPO_NAME BRANCH_NAME [DIRECTORY_NAME] [BITBUCKET_ACCOUNT_NAME]
#
#

BITBUCKET_ACCOUNT_NAME=akrabat
GITROOT=git@bitbucket.org:${BITBUCKET_ACCOUNT_NAME}

if [ -z "$1" ]; then
    echo "Usage is git-export.sh {repo_name} [{branch_name = master}] [{dir_name = repo_name}]"
    exit 1
fi


REPO_NAME=$1
BRANCH_NAME=$2
THIS_DIR=$3

if [ -z "$BRANCH_NAME" ]; then
    BRANCH_NAME=master
fi
if [ -z "$THIS_DIR" ]; then
    THIS_DIR=$REPO_NAME
fi

if [ -d "$THIS_DIR" ]; then
    echo "Error: directory '$THIS_DIR' already exists."
    exit 1
fi

echo "Exporting $BRANCH_NAME branch of $REPO_NAME into ./$THIS_DIR..."
mkdir $THIS_DIR
git archive --format=tar --remote=$GITROOT/$REPO_NAME $BRANCH_NAME | tar -xf - -C $THIS_DIR

echo "Done"
echo ""

Not the most complicated script in the world, but I never need to think about it again and it's easy to call from Phing and other deployment scripts and doesn't require a local clone to exist.
