Hi all,
I'm trying to write a simple script that if provided an argument, uses
that, or if nothing is provided, uses a predefined string.
if [ -n $# ]
then
WORDS=$1
else
WORDS="these are some words"
fi
echo $WORDS;
The second case is always comes back "".
But if I write
WORDS='these are some words'
echo $WORDS
I get the assigned string.
Why doesn't the assignment work when inside an if/then? How do I make
it work? What's the difference between the case where the assignment is
inside the if/then and outside the if/then?
TIA,
Mike Wright
