I believe you are referring to the SHA1 value.

Why check for it first, why not just do a 'git pull origin' and be done with it.

But, if you really want to inspect the HEAD revision's SHA1 value of a
remote repository, you can use the following command:

  $ git ls-remote origin HEAD

If you wanted to know every HEAD of every branch/tag on the remote
repository, then just do:

  $ git ls-remote origin


For more information see the following help for the 'git ls-remote' command:
