Separate the switches into --outdir and --suffix. There really
is no way to perform this kind of "substitution" since the shell
will be expanding the '*' into whatever happens to be there --
or the original string if no files match when the command is run.

It sounds as though they want something that will append a suffix
to the input files to show that they have been processed. In that
case:

    my $base = basename $path;
    my $path = $outdir . '/' . $base . '.' . $suffix;

    open my $outfh, '>', $path or die "trying...";

This will turn /foo/bar/input.file into /out/dir/input.file.suffix
after processing.
