git rev-parse: RefName ======> SHA1
git name-rev:  SHA1    <=====  RefName

# Convert the reference name HEAD to its corresponding SHA1
git rev-parse HEAD   # Assuming for the sake of example that it outputs 1234567

# Convert the SHA1 (1234567) into its reference name (should output HEAD in our example)
git name-rev 1234567
