Re: Fully Qualified Hostname in ITM

And you can see from the ITMhostName script (UNIX/Linux) itself that it
gets 4 potentially distinct hostname values from uname and hostname
variants:

# The hostname command returns the local host name.
localName=`uname -n`
localSName=`print $localName | cut -d'.' -f1`
# hostname value
localHName=`hostname 2>/dev/null`
# short hostname value
localHSName=`print $localHName | cut -d'.' -f1`

networkIP=""
networkName=""
networkSName=""

# This will first find the localname - then append to the same
# line the local hostname if the flag is specified and it is different
# than the localname
if [ "$Option" = local ]; then
  [ "$Length" = long ] && localresult=$localName || localresult=$localSName
  if [ "$Mode" = "many" ]; then
    [ "$Length" = long ] && localhostname=$localHName ||
localhostname=$localHSName
    if [ "$localhostname" != "$localresult" ]; then
      localresult="$localresult $localhostname"
    fi
  fi
  print $localresult


So it tries to cover the bases....
