Hi Victor,

An expanded version of the above. It takes multiple arguments and cuts
out the repetition in the output.
$ cat lup

set -eEu -o pipefail
shopt -s failglob
trap 'echo ${0##*/}: line $LINENO: unexpected exit: $? >&2' ERR
for f; do
readlink -e "$f"

sed '

xargs ls -Uld |
awk '!a[$0] {print; a[$0] = 1}'
