Git working directory exit code

In “Check if Git working tree is dirty”, git diff and git status were used to check if a working directory is dirty.

To get the exit status code, you can extract the value from the shell variable $?:

$ git diff --quiet
$ echo $?

Exit code of 0 means the working directory is clean. Exit code of 1 means the working directory is dirty.

Code Type
0 Clean
1 Dirty

For faster performance, you can use git diff-index since it’s a lower level operation:

$ git diff-index --quiet HEAD
$ echo $?
