Making Tab Completion Case Insensitive in Bash

When using the bash command line, I prefer to be able to type "cd dow" and then hit Tab and have bash fill in Downloads. By default, in order to access Downloads, I would have to type an uppercase "D" ("cd Dow") and hit Tab. Luckily, this is very easy to change.

Simply type the following at the prompt:

set completion-ignore-case on

To make it permanent, add the line to either /etc/inputrc or $HOME/.inputrc. The next time you log in this will be set automatically.
