git-status - Show working tree status
git-status <options>...
DESCRIPTION
Examines paths in the working tree that has changes unrecorded to the index file, and changes between the index
file and the current HEAD commit. The former paths are what you could commit by running git-update-index before
running git commit, and the latter paths are what you would commit by running git commit.
If there is no path that is different between the index file and the current HEAD commit, the command exits with
non-zero status.
The command takes the same set of options as git-commit; it shows what would be committed if the same options are
given to git-commit.
OUTPUT
The output from this command is designed to be used as a commit template comments, and all the output lines are
prefixed with #.
