bash - How to check the validity of a remote git repository URL? -

-

within bash script, simplest way verify git url points valid git repo , script has access read it?

protocols should supported git@, https://, , git://. curl fails on 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 check see if url syntactically correct, need verify repo exists @ url location entered within bash script.

as seen in this issue, can use git ls-remote test address.

if need debug git calls set git_trace=1. eg:

env git_proxy_commadn=myproxy.sh git_trace=1 git ls-remote https://...

"git ls-remote" quickest way know test communications remote repository without cloning it. hence utility test issue.

you can see used detecting address issue in "git ls-remote returns 128 on repo".
