hmmmm, here's here.

yup=`scp foo captgoodnight@192.168.*.*:/home/captgoodnight`
echo "$yup"

yup=`scp food captgoodnight@192.168.*.*:/home/captgoodnight`
food: No such file or directory
echo "$yup"

or

yup=$(scp food captgoodnight@192.168.*.*:/home/captgoodnight)
food: No such file or directory
echo "$yup"

yup=$(scp foo captgoodnight@192.168.*.*:/home/captgoodnight)
echo "$yup"
