Exporting whole MySQL databse to CSV files

csv-export.sh

#!/bin/bash
# USAGE: Will create a .tar.gz with CSVs of all tables in schema.  
# Configure below and run as root (i.e. the user mysql runs as)
# 
# The script will (or should) SELECT * INTO OUTFILE your tables
# and save them into csv files under /tmp dir first, then name them 
# like the tables and move them thogether into a directory. Then 
# it will tar everything together and chown you the tarball. 

# Schema to export:
DB=schemaname

# Directory to export files into: (before tar-ing)
DIR=csvs-$DB-$(date +%Y-%m-%d-%H-%M-%S)/

# Final tarball's location:
TARBALL=csvs-$DB-$(date +%Y-%m-%d-%H-%M-%S).tar.gz

# Config file for mysql password: (you would have to enter it many times)
CONFIG=/home/burny/.my.cnf
# This file looks sth like this (my.cnf-style):
# > [mysql]
# > user = sampleuser
# > password = samplepasswd

# Set owner to this user: (lets you access the export)
OWNER=bxt:bxtsgroup

# Name of file to save tables names to
SCHEMAFILE=schema.txt

# ---------------------------------------------------------------------
# Now following: the script. You shuldn't have to change
# somthing after this line, but you might save you some 
# trouble if look at stuff before running it as root ;)
