Count number of lines in a git repository

Question

How would I count the total number of lines present in all the files in a git repository?

git ls-files gives me a list of files tracked by git.

Answer 1

If you want to find the total number of non-empty lines, you could use AWK:

git ls-files | xargs cat | awk '/\S/{x++} END{print "Total number of non-empty lines:", x}'

This uses regex to count the lines containing a non-whitespace character.
