UNIX System Information - SGI IRIX

OS Version

On SGI IRIX systems uname supports an extra option to give a more readable form of the operating system revision:

% uname -R
6.5 6.5.11m
% uname -aR
IRIX alnus 6.5 6.5.11m 01101246 IP32

Note that for some SGI systems the IRIX reported 'IP' number does not directly correspond to the hardware 'IP' number (see sgistuff.net : Hardware : Tables. In particular the SGI Indy reports as an 'IP22' (which corresponds to the R4x00 based SGI Indigo 2 hardware), but the hardware is an 'IP24'.
