# git-remote-entire: add --version and --help flags.

`7cfeb0d`→[main](/content/gh/entireio/cli/commits/main/index.html)·

toothbrush·1mo ago·2 files·+70 added/-0 removed

Only activate when passed as the sole argument; git always invokes the
helper as `git-remote-entire <remote> <url>`, so these never collide.
