assigning SED output to a variable = trouble!
i'm on a Mac running BSD unix.

i have a script in which i ask the user to input the name of a mounted volume. i then call SED to substitute backslashes and spaces in place of the spaces. that looks like this:

echo "Enter the name of the volume"
read Volume
echo "You've chosen \"$Volume\""
# remove spaces from name of Volume
echo $Volume | sed 's/ /\\ /g'

if i enter "old mac hd" for the volume name when prompted, it returns with:
"old/ mac/ hd" which is perfect!

but... if i then want to assign this output to a variable for later use, it doesn't work:

uVolume=`echo "$Volume" | sed 's/ /\\ /g'`
echo $uVolume

this returns:
"old mac hd" and NOT "old/ mac/ hd" as i'd like. and, as i'll be using the full directory path in a later portion of the script, i kinda need those backslashes!

i'm assuming that i'm missing simple syntax here. thoughts/comments/questions?
