I would use $() instead of `` because the quoting is a lot easier to deal
with; in particular, the inner \` ... \` doesn't need the backwhacks if you
use $() instead.
Other observations: Paul Graydon suggested find, but you probably want to
use -maxdepth (warning, not in POSIX).
Untested but should be close:
eval "$(echo -n "< $input "
find . -maxdepth 1 -name '*.meta' -print0 |
xargs -0 awk '/Filter:/ {gsub(".", "\\&", $2);
f = $2;
sub("\\.\\m\\e\\t\\a$", "", f);
print "./" $2, "-r", f, "|";
nextfile }' |
sed '$s/|$/>output/')"
