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

xargs will do what you want:

git ls-files | xargs cat | wc -l

But with more information and probably better, you can do:

git ls-files | xargs wc -l

Answer 2

: | git mktree | git diff --shortstat --stdin

Or:

git ls-tree @ | sed '1i\\' | git mktree --batch | xargs | git diff-tree --shortstat --stdin

Answer 3

I was playing around with cmder (http://gooseberrycreative.com/cmder/) and I wanted to count the lines of html,css,java and javascript. While some of the answers above worked, or pattern in grep didn't - I found here (https://unix.stackexchange.com/questions/37313/how-do-i-grep-for-multiple-patterns) that I had to escape it

So this is what I use now:

git ls-files | grep "\(.html\|.css\|.js\|.java\)$" | xargs wc -l

Answer 4

Try:

find . -type f -name '*.*' -exec wc -l {} +
