pre-commit-db-export

#!/bin/sh
#
# A hook script to export your database on every commit.
#
# The export is saved to a temp file. If the export
# fails, the file is trashed. Otherwise it overwrites the tracked file.
#
# Called by "git commit" with no arguments.  The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
#
# To enable this hook:
# $ cd /path/to/repo
# git clone https://gist.github.com/rpowis/5198224.git .git/hooks/pre-commit
# chmod +x .git/hooks/pre-commit

# Create directory if it doesn't exist

    mkdir -p ${DB_DIR}
