If you are like me, you use the Terminal a lot. By default the terminal has case-sensitive tab completion, meaning that if you type ‘s’ and press tab it would not suggest a file/folder called ‘S’.
Luckily, this is quite an easy fix.
Create, or if you already have it; edit, a file called .inputrc in your ‘Home’ folder.
In it write:
set completion-ignore-case On
Restart Terminal and you are done!
