Start using CLI more and more with mycli

July 18, 2018 Written By Marco Monteiro

Ever since I moved into Linux I started using the CLI even more. Don’t get me wrong, I used it quite a lot on Mac. However if there was one thing that I normally didn’t use it for was for mySQL. However a few days ago I discovered mycli. Since then I gotta say. Love it!

Here’s a bit more about the tool.

Install the thing first:

$ sudo apt-get install mycli

Usage:

$ mycli --help

	- mycli my_database
	- mycli -u my_user -h my_host.com my_database
	- mycli mysql://my_user@my_host.com:3306/my_database
