If loop question

Hi I have script

Code:
if [ `echo $HOSTNAME | grep 'hd' ` ]; then
  echo "Found Node"
 
else
  echo "Sorry this is not a node"

I need to add conditions "nn" ,"rm", and "hh" in the same line along with "hd" .Can this be done or do I need to use elif

You could do that with grep -E:grep -E 'hd|nm|rn|hh' , however this is cumbersome and unnecessary, since the shell has builtin pattern matching:
Code:
case $HOSTNAME in
  (*hd*|*nn*|*rm*|*hh*)
    echo "Found Node"
  ;;
  (*)
    echo "Sorry this is not a node"
  ;;
esac
