I have searched in google, they say "git ls-remote git-url" can say whether git repo exists or not.
But i have a problem when use this command to check github unexisting https git url.
for example, when I run below command, it will require input username and password.
$ git ls-remote https://github.com/grant/noexisted.git
I only want to check whether the repo exists or not, and I call "git ls-remote" command in ruby code, so how to skip this auto shell prompt?
