git status typo: what does the extra space do? -


i typed 

git status - uno

and got response

# on branch xyz_xyz nothing commit (working directory clean)

i knew had made changes, wasn't right. saw typo... meant type 

git status -uno

which gives correct response:

# on branch xyz_xyz # changes not staged commit: #   (use "git add <file>..." update committed) #   (use "git checkout -- <file>..." discard changes in working directory) # #       modified:   abcd/xyz.cpp #       ... #

(note: git status -uno typically slow on system, in typo case response instant.)

what status git checking when typed first command?

git status - uno alternative spelling of git status -- uno, can spelled git status uno. of these commands check status of uno path in repository. since 1 doesn't exist, git status quick in telling there nothing commit.

git commands accept optional pathspecs use -- separator disambiguate between pathspecs , arguments precede them, such options , branch/commit names. use of - , -- separator decades-old unix convention, invented enable specifying arguments start -.
