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.
I'm looking for a command to cat all those files. Something like
git ls-files | [cat all these files] | wc -l
xargs will let you cat all the files together before passing them to wc, like you asked:
git ls-files | xargs cat | wc -l
But skipping the intermediate cat gives you more information and is probably better:
git ls-files | xargs wc -l
