@shitpisscum Case insensitivity is brain damage as computers are not case insensitive and will you face issues when faced with two folders called "Documents" and "documents" on windows.

You can easily get GNU bash to tab complete to capitals if someone was braindead and decided to start a folder or a filename with a capital letter, it's as simple as adding;
bind "set completion-ignore-case on"
to .bashrc
or
set completion-ignore-case on
to /etc/inputrc to set it for all users.
