The following checks for the existince of one variable being passed on the command line, and exits if it isn't there:

if [[ -n $1 ]]; then
  print
else
  print
  print "   ** Enter Node Name (i.e. createServerGroup.sh SpherionServerGroup) **\n"
  exit 1
fi

How can I check for two variables being passed in the same if statment?

Thanks,

Lisa

Why not check for the number of arguments first and then handle the cases of one or two args? $# will contain the argument count, so:

if [ $# = 2 ]; then
  # two args
elif [ $# =1 ]; then
  # only one arg
else
  # something I'm not prepared to deal with
fi

should do the trick.
