Generate CHECK TABLE statements for all MySQL database tables on a server

This command will generate "CHECK TABLE `db_name.table_name` ;" statements for all tables present in databases on a MySQL server, which can be piped into the mysql command. (Can also be altered to perform OPTIMIZE and REPAIR functions.)

Tested on MySQL 4.x and 5.x systems in a Linux environment under bash.

What others think

What the ... Please stop tormenting that poor animal (Yes, I mean the cat: http://sial.org/howto/shell/useless-cat/).

sed "s/#.*//g" /etc/my.cnf | ...

Does the job. Also why grep, awk can do that:

sed "s/#.*//g" /etc/my.cnf | gawk -F"=" '/datadir/{print $2}'

Btw., got rid of the tr, too..

Hell, lets do it all in sed:

sed -n "s/#.*//g;/datadir/s/datadir=//p" /etc/my.cnf

And find has regular expression support:

find . -mindepth 2 -name "*db.opt*"

And sort -u is the same as 'sort | uniq'

You really seem to like your semicolons. Awk and sed only need them to separate multiple statements.
