git get-tar-commit-id

Read a tar archive created by git archive from the standard input and extract the commit ID stored in it​. It reads only the first 1024 bytes of input, thus its runtime is not influenced by the size of the tar archive very much​.

If no commit ID is found, git get-tar-commit-id quietly exits with a return code of 1​. This can happen if the archive had not been created using git archive or if the first parameter of git archive had been a tree ID instead of a commit ID or tag​.
