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.

Sorting by rows

Save the script as: sort_file

Usage: sort_file < sort_me.csv > out_file.csv

This script was originally posted by Admiral Beotch in LinuxQuestions.org on the Linux-Software forum.

I modified this script to make it more portable.

Puts every word from a file into a new line

Simply translates whitespace to newlines. Could be enhanced to compress out extra newlines, but that might be better handled in the next tool down the pipe, with eg uniq(1).

Sort a list of numbers on on line, separated by spaces.

You can replace "sort -nu" with "sort -u" for a word list sorted or "sort -R" for a random-sorted line

(edit: corrected)

List commands with a short summary

Obviously, you can replace 'man' command with any command in this command line to do useful things. I just want to mention that there is a way to list all the commands which you can execute directly without giving fullpath.

Normally all important commands will be placed in your PATH directories. This commandline uses that variable to get commands. Works in Ubuntu, will work in all 'manpage' configured *nix systems.

Duplicating service runlevel configurations from one server to another.

And then to complete the task:

Go to target host;

ssh host

Turn everything off:

for i in `chkconfig --list | fgrep :on | awk '{print $1}'` ; do chkconfig --level 12345 $i off; done

Create duplicate config:

while read line; do chkconfig --level $line on; done < foo

Find and delete oldest file of specific types in directory tree

This works on my ubuntu/debian machines.

I suspect other distros need some tweaking of sort and cut.

I am sure someone could provide a shorter/faster version.
