My practice is to start with '#!/bin/sh' and migrate to '#!/usr/bin/env 
perl' as complexity increases.

We need to see the full range of file names the OP is trying to deal with.

Thank you for helping me realize that my solution fails to print the 
resolved absolute file name.  Here is the updated solution:

2024-05-02 21:57:56 dpchrist@laalaa ~
$ touch 'name with spaces'

2024-05-02 22:23:01 dpchrist@laalaa ~
$ touch 'name with
 > newline'

2024-05-02 22:28:36 dpchrist@laalaa ~
$ perl -MString::ShellQuote '-MFile::Spec::Functions qw(rel2abs)' -e 
'print shell_quote(map { rel2abs $_ } @ARGV), "\n"' name*
'/home/dpchrist/name with
newline' '/home/dpchrist/name with spaces'
