# #automysqlcheck.sh
#
# This is a small bash script that checks all mysql databases for errors
# and mails a log file to a specified email address. All variables are
# hardcoded for ease of use with cron. Any databases you wish not to check
# should be added to the DBEXCLUDE list, with a space in between each name.
#
# Note that DBEXCLUDE will only work with GNU sed, as BSD regular expressions
# on Darwin seem to have some trouble with word boundary anchors.

#=====================================================================
#
# VER 1.3 - (2006-12-02)
# Added --host=$DBHOST in mysql commands, so it's useful for non-localhost situations
# Jake Carr
# VER 1.2 - (2006-10-29)
# Added "\`" arround the tables in $DBTABLES, otherwise it'll create
# errors if tablenames containt characters like -.
# Modified by Mickael Sundberg
# VER 1.1 - (2005-02-22)
# Named script automysqlcheck.sh
# Added PATH variable to make this script more CRON friendly
# Removed the $DBTABLES loop and replaced it with single command
# that executes the CHECK TABLE command on all tables in a given DB
# Changed code to only check MyISAM and InnoDB tables
# Cleaned up output to make the email prettier
# Modified script to skip databases that have no tables
# Modified by eyechart
# VER 1 - (2004-09-24)
# Initial release by sbray@csc.uvic.ca
