   The argument to "if" is interpreted as a command. In this case the
   argument, $0, is the name of the script, so the script calls
   itself, then calls itself, then calls itself, then calls itself,
   then calls itself, then calls itself, then calls itself.........
   ad infinitum, ad nauseam......

   What you probably want is:

if [ "$0" = "$1" ]
then
   echo "HELLO"
fi
