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.

The best solution, to me anyway, is buried in the comments of @ephemient's answer. I am just pulling it up here so that it doesn't go unnoticed. The credit for this should go to @FRoZeN (and @ephemient).

git diff --shortstat `git hash-object -t tree /dev/null`

returns the total of files and lines in the working directory of a repo, without any additional noise. As a bonus, only the source code is counted - binary files are excluded from the tally.

The command above works on Linux and OS X. The cross-platform version of it is

git diff --shortstat 4b825dc642cb6eb9a060e54bf8d69288fbee4904

That works on Windows, too.

For the record, the options for excluding blank lines,

• -w/--ignore-all-space,
• -b/--ignore-space-change,
• --ignore-blank-lines,
• --ignore-space-at-eol

don't have any effect when used with --shortstat. Blank lines are counted.
