Line numbers in `cat` command

TIL: With extra flag -n we can print the line numbers in cat command.
(No need to load file in vim for line numbers anymore :) )

Command

$ cat -n filename

Bonus

You can use bat (as they call it, cat with wings), if you want:

1. Syntax Highlighting
2. Line numbers
3. Paging
4. pipe like in cat.
5. etc
