How to find out the amount of lines of documents in a folder using shell scripts?

Question

I have a folder full of my code, what shell script can I use to find out the total amount of lines of code?

Answer 1

A very simple solution would be wc -l ./*, which counts the number of lines in all files, as well as each file individually.

If you want something more sophisticated, use sloccount. You can install it e.g. using Homebrew:

sudo brew install sloccount

Run it on the folder containing the code, like this:

sloccount .

It'll give you lines by programming language and directory.

Answer 2

If you just want to count the number of lines in text files, try wc -l *.
