in reply to Problems with special characters in Linux file names

You use shell_quote where you shouldn't. (And, arguably, you don't use it where you should.)

-e needs a path, not a piece of shell code. 

my $src_qfn = 'BulletinV3, 1 Montana 20xx-xx-xx (print).pdf_FN_TEMPLAT
+E';

if (-e $src_qfn) {
   ...
} else {
   ...
}

Or with error checking: 

my $src_qfn = 'BulletinV3, 1 Montana 20xx-xx-xx (print).pdf_FN_TEMPLAT
+E';

if ( stat( $src_qfn ) ) {
   ...
} else {
   die( "Can't stat `$src_qfn`: $!\n" ) if !$!{ ENOENT };
   ...
}

As for that message of command at the bottom, 

system( "zenity",
   "--title" => "Rename problem",
   "--width" => 400,
   "--error",
   "--text"  => "Can't rename `$src_qfn` to `$dst_qfn`: $!",
)

    I put the code snippet, which came directly from my program, into a file and, it works! There is so little code, I don't know how it works in one place and NOT the other.

    I'll post another comment as soon as I find what I did wrong.

    Sorry

      Sorry, sorry, sorry! Operator error! It wasn't the filename, the problem was I didn't include the path. I added the path and all is well.

      I'm so embarrassed. Please ignore this post!

        Don’t be embarrassed. Almost every monk has a slew of ridiculous mistakes in their back catalog. Learning and building are more important than the bumps along the way.
