That's cool. I think you can still reduce the bracketed part to
[0-9\.]. However, the way it works now is that it prints your kernel
version and the associated gcc version. So, it needs a bit more work.
Oh, and distros often tend to add extra version fields to their
packages with - and _.
This is what I came up with, which unfortunately is getting long
again. Alexander might be right that `cat /proc/version' is the way to
$ sed -r 's/.*(Linux version [^ ]+).*(gcc version [^ ()]+).*/\1 \2/'
Linux version 188.8.131.52-7 gcc version 4.0.3
And what it does for the Debian system.
$ sed -r 's/.*(Linux version [^ ]+).*(gcc version [^ ()]+).*/\1 \2/' foo
Linux version 2.6.18-3-686 gcc version 4.1.2
