You can look at how git does it: http://git.kernel.org/?p=git/git.git;a=blob;f=GIT-VERSION-GEN;hb=HEAD > > What would be the best command to get a unique identifier? "git rev-parse HEAD" for a unique identifier, but "git describe" is more convenient/useful. > Do I need the 40 digit hash id? Normally 7 or 8 are sufficient. > How can I make sure that a shorter hash id will be unique? You can't. Even the 40 digit hash is "only" cryptographically unique. But within a project 7 or 8 digits are unique enough for practical use.
