I would replace your script with this one:

#!/bin/sh
W=3D"\/Users\/edgarm\/tmp\/$1\/."
echo $W
sed -n -e '/^File/H' -e '${x; s:\n: :g; s:File ::g; s:\(.*\):\1=20=20
"'$W'":; p; }' < $2 | xargs cp

What does it do?

- -e '/^File/H'	When pattern buffer starts with 'File', append it to=20=20
hold buffer
- -e '${		When at the last line, start a function
  x;		Exchange hold and pattern buffer
  s:\n: :g;	Replace newline with a space
  s:File ::g;	Delete 'File '
  s:\(.*\):\1 "'$W'":;
		Append $W to pattern buffer
  p; }'		Print pattern buffer and close function

Note: The pattern buffer is also the input buffer.

Thanks for a nice sed training or exercise...

Kind regards, Edgar.
