This bash script creates a unique platform identifier string for linux (including cygwin) and solaris. It is useful for creating directory trees on network shared volumes that store data for different OS’s.

Your script doesn’t run on a Solaris system.
uname doesn’t have a -o option in Solaris (apparently), so your function is blowing up.
I am not surprised. It was never intended to work for a non-linux distribution. If you manage to get it working for solaris and want me to post it, I would be happy to.
Thank you for pointing this out.
I think that I fixed the problem. I needed a Solaris variant to test it and found OpenIndiana but it took awhile.
