in reply to can create with File::Temp but not unlink

Good monk ChOas showed me that I needed to import "unlink0".   And I replaced $path in DUNWERK2 with $filehandle and renamed function to NOWITWERX.   Also fixed typo by replacing my$filename with my $filename in 2 places.  

That seems to fix everything, except DUNWERK still doesn't appear to create tempfile.   Since I can now create and unlink with NOWITWORKS syntax, this is good enough for now.   Thanks and ++ to ChOas.   8^)

Updated codelet below.

    I can't get File-Temp to install via PPM (its there but ...) but the readme cautions about permissions on the dir. However, DUNWERK uses:
    my $fh = tempfile($template, DIR => $dir);
    and the rest use:
    (my $fh, my $filename) = tempfile($template, DIR => $dir);
    so ... array returns in scalar context or something?

[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
[stevieb]: I do date and time transformations in both Perl and Python, but not frequently enough to not have to search for the format params etc ;)
