Point taken, but it was meant to illustrative of basic shell issues on a
system controlled by the user rather than a robust, catch anything
thrown at us, backup strategy. Filenames with spaces break most simple
/bin/sh scripting techniques anyway...
x=
for f; do
test -x $f && x="$x $f"
done
You have to muck around with later shells things like bash's arrays
instead.
Cheers,
Ralph.
