Truncate all Tables in a MySQL Database

Here is a handy script to truncate all the tables in a MySQL database. I use this sometimes to wipe out an entire database before loading in some production data to replicate a customer problem:



This script isn't perfect -- it should really prompt the user for his password so that these passwords don't get into bash history logs. In a later post I'm going to talk about using this command in conjunction with some command line MySQL command to load a remote database locally for testing.
