Actually there is at least one special case: AIX. AIX does it its own way: uname -r returns the minor version of the OS, while uname -v returns the major version; this is the output on AIX 4.3:

bash$ uname -s AIX bash$ uname -r 3 bash$ uname -v 4

With your code the system will appear to have AIX 3 intead of 4...


The very nature of Perl to be like natural language--inconsistant and full of dwim and special cases--makes it impossible to know it all without simply memorizing the documentation (which is not complete or totally correct anyway).

    Whoa. I have never caught that before, never had to worry about versions on AIX. Thanks, I will change my code accordingly. You Rock!

    It has been suggested to rename Perl 6 in order to boost its marketing potential. Which name would you prefer?
