Formatting the Output of MySql Queries With \G

Running queries on wide tables using the MySQL command line can often result in unreadable output:

SELECT * FROM mysql.user;

You can format this output so that the columns are displayed as key: value pairs by using \G rather than ;, like so:

SELECT * FROM mysql.user \G
