How do you set the terminal output's width to 80 columns in MariaDB?

I am not referring to database columns, I am referring to Terminal Columns. How do you ask MariaDB to format its output for a standard 80 columns terminal ? Right now it outputs in however many columns fit the output so I basically have to fullscreen the terminal which is inconvenient.

Solution

I assume with "MariaDB" you mean the command line client.

The simple answer is: you can't.

If your results are hard to read, try vertical output, instead of ; as a delimiter of a SQL statement use \G or start command line client with option -E.

MariaDB [test]> select * from information_schema.columns limit 1\G
