Use double quotes instead of single quotes.  variable substitutions occur
inside double quotes, but not inside single quotes.  Observe:

	% /bin/sh
	$ RHOST=apple-gunkies
	$ echo "here I am on $RHOST!"
	here I am on apple-gunkies!
	$ echo 'here I am on $RHOST'
	here I am on $RHOST

Quoting from our sh(1):

     A character may be quoted by preceding it with a \.  \new-
     line is ignored.  All characters enclosed between a pair of
     quote marks (''), except a single quote, are quoted.  Inside
     double quotes ("") parameter and command substitution occurs
     and \ quotes the characters \ ' " and $.
