-N removes header

-s removes separator chars

-r raw output

After using these options, the MySQL ouptut can be used with pipes very easily

echo -e "[client]\nuser = YOURUSERNAME\npassword = YOURPASSWORD" > ~/.my.cnf

The file .my.cnf located at user's home directory is used for mysql login. If this file exists, then

mysql -uYOURUSERNAME -pYOURPASSWORD database -e 'SOME SQL COMMAND'

can be replaced with

mysql database -e 'SOME SQL COMMAND'

It saves you from typing!

This is valid for mysqladmin and mysqldump commands as well.

Be aware of using the --password argument as it will appear your password in plain text on the screen. You may use -p argument instead, it will prompt you to enter you password in hidden mode.

This loops through all tables and changes their collations to UTF8. You should backup beforehand though in case some data is lost in the process.

Useful for monitoring both MySQL and the server load at the same time.

I have this on a daily cronjob to backup the commandlinefu.com database from NearlyFreeSpeech.net (awesome hosts by the way) to my local drive. Note that (on my Ubuntu system at least) you need to escape the % signs on the crontab.

watch -n 1 mysqladmin --user=<user> --password=<password> processlist

Watch is a very useful command for periodically running another command - in this using mysqladmin to display the processlist. This is useful for monitoring which queries are causing your server to clog up.
