Within a bash script, what would be the simplest way to verify that a git URL points to a valid git repo and that the script has access to read from it?

Protocols that should be supported are git@, https://, and git://. Curl fails on the git:// protocol.

git@github.com:UserName/Example.git
https://UserName@github.com/UserName/Example.git
git://github.com/UserName/Example.git

Note: I’m not asking to check to see if a URL is syntactically correct, I need to verify that a repo exists at the URL location entered from within a bash script.

    As seen in this issue, you can use git ls-remote to test your address.

    If you need to debug the git calls set GIT_TRACE=1. eg:

    env GIT_PROXY_COMMAND=myproxy.sh GIT_TRACE=1 git ls-remote https://...

    "git ls-remote" is the quickest way I know to test communications with a
    remote repository without actually cloning it. Hence its utility as a test for this
    issue.

    You can see it used for detecting an address issue in "git ls-remote returns 128 on any repo".
