Use tokei
tokei is a blazing fast source code line counter. It supports a lot of different languages.
If I did a count in my TIL repository it would output the following:
$ tokei

Supported Languages
The help message (--help) indicates that you can get a list of supported languages and their extensions using: --languages.
-l, --languages Prints out supported languages and their extensions.
