If you maintain a log of an interactive MySQL session, you can refer back to it later to see what you did and how. Under Unix, you can use the script program to save a log of a terminal session. This works for arbitrary commands, so it works for interactive mysql sessions, too. However, script also adds a carriage return to every line of the transcript, and it includes any backspacing and corrections you make as you’re typing. A method of logging an interactive mysql session that doesn’t add extra messy junk to the log file (and that works under both Unix and Windows) is to start mysql with a --tee option that specifies the name of the file in which to record the session:[11]

% mysql --tee=tmp.out cookbook

To control session logging from within mysql, use \T and \t to turn tee output on and off. This is useful if you want to record only parts of a session:

mysql> \T tmp.out
Logging to file 'tmp.out'
mysql> \t
Outfile disabled.

A tee file contains the queries you enter as well as the output from those queries, so it’s a convenient way to keep a complete record of them. It’s useful, for example, when you want to print or mail a session or parts of it, or for capturing query output to include as an example in a document.
