Question

I am trying to see if a new line has been matched. The reason is that my script asks for the user’s name. If they press enter, then a default name is used.

The problem is I cannot seem to check whether they have pressed enter, or used a name of their own. I have searched a lot on the net, and can’t find a working answer. Here is what I have tried to implement:

if [ `expr match "$temp1" "\n"` != 0 ]

Very new to this. Thanks!

Try something like this:

#!/bin/sh
/bin/echo -n "Who? "
read name
if [ "x$name" != "x" ]
then
    echo "Hi $name"
else
    echo "Hi no-name"
fi
