I think it would be better for you to redefine your question & target, to make it clear. are you sure that the SVN revision of the system is what you are after? As for Linux, not "uname" nor "lsb_release" are any good to get details for the OS version, since the first will tell you mostly about the kernel and related info while the second simply wont even exist in non LSB compliant Linux distributions. About Haiku and lsb_release now ..well its only natural to be missing from haiku :P Haiku is an alternative BeOS like OS that shares a little if anything with Linux , and lsb_release is a command that shows Linux Standard Base (LSB) related info on lsb compliant systems , which of course HAIKU isn't since its not Linux or even Linux-based. -- Regards, Alex-P.
