HP-UX Support?

[blentzgh]

elif [ "${OS}" = "HP-UX" ] ; then
  set -- `swlist -l bundle "HPUX*OE"`
  until [ $# -eq 0 ]; do
    case "$1" in (*HPUX*OE*)
      REV="$2"
      break;;
    esac
    shift
  done
  ARCH=`uname -m`
  OSSTR="${OS} ${REV}(${ARCH})"

Tested on a handful of my systems gives output like:

• HP-UX B.11.31.1403(ia64)
• HP-UX B.11.31.1209(ia64)
• HP-UX B.11.11.0406(9000/785)

Also, FWIW:

• the thing seems to be portable, you might swap bash for sh.
• All supported (e.g. current) versions of AIX support 'oslevel -s' which will return the major/minor level (AIX 7.2), the technology / maintenance level (TL or ML for oldies) and the Service Pack and BUILDDATE (in YYWW double-digit year, double-digit week of year, format) AIX 7200-03-01-1920. I think anything since AIX 5.2 or 5.3 supports oslevel -s. Some people still have AIX 4.3.3 or older, but hell, those boxes are way out of support from IBM.
