Hello NetPeople:-)

	I have a sh program that wants input at the command line.
However, I need an error out if the unser does not input at the command line.
ie:


if [ ${1} = "" ]
then
	echo "Please enter your option now."
	read $1
else
	echo "${1} was inputed at the command line"
fi

However, this file will get the following error message.

jim: test: argument expected

How can I do this?

Thank you,
James D. Corder
