I need to add the current date to file names within a document, replacing the old date. (Goal: a cron job of scripts to create fresh files for download, then update the links.) 
#!/usr/bin/perl -w
use Date::Format;
$date=(time2str("%Y-%m-%d", time));
print "\n\n$date\n\n";
## works

's!(\d\d\d\d-\d\d-\d\d)(-[a-z_]{5,30}\.zip)!\$date$2!g' filename.html;
## doesn't work

[download]

I have the pieces working, but not the whole. I have tried everything that I can think of (limited severely by having no noticeable programming experience and Perl experience limited to installing others' scripts).

If I need to explicitely Open the file, make the changes then Close/save it, I didn't get that far in reading (books and forums (forae?) or I've skipped it).

I know that this has been answered generally several times here and in other venues, but I haven't found a "solution" which I can understand enough to apply successfully.

Thanks,
Craig
