The operating system release

What’s the ruby way to find out “the operating system release”? Thanks.

IMO there is no simple way to find it out.
I would first test the PLATFORM constant.
If it is some kind of UNIX you can use
uname
or the uname module from
http://www.ruby-lang.org/raa/list.rhtml?name=sys-uname

For Windows I don’t know.

You can use the PLATFORM constant to get the OS:

irb(main):001:0> PLATFORM
"i586-mswin32"

If you want to get the version of the OS, under linux (and perhaps other
unix) you can call the command “uname”.

os_version = uname -a

Yes. I knew this. But my goal is to implement a Unix uname clone. So I
can’t use uname itself to do that.

Well, there is /etc/redhat-release on Redhat and Mandrake systems. Maybe you could check for this file, and maybe there are like files on other distributions like Suse and Debian?
