Cleanly run commands that require mysql running
View mysqldo.sh
#!/bin/bash
# Executes the provided arguments as a shell command with a twist: if mysql is
# not already running: starts mysql, runs the commands, and stops mysql.
# Example usage:
# - mysqldo mysql -u root -p # will open an interactive shell and will stop mysql
# # when you leave the shell
# - mysqldo 'echo "show databases;" | mysql -u root -p"my_password"'
# # note that if your commands involve pipes or anything that the shell
# # interpretter would not pass to mysqldo as arguments, you should wrap the
# # entire command in quotes.
