I'm a very frequent user of wget, but must admit I haven't dived too deep into various options - but as far as I can tell, what I'm about to suggest is not a current feature. If it is, can somebody tell me how to access it? 0:-)
What I'm suggesting is something similar to -N (check timestamp and download newer) and may perhaps be used more as a modifier to -N than a seperate option. I occationally make a mirror of certain site with wget, and then throw it into an archive. Unfortuanately, a few months (year) later when I want to catch-up with any updates, I either have to mirror the whole thing again or locate the old archive and unpack it (and I haven't necesserely preserved the whole directory structure). What I would love was the ability to specify (through an option) an arbitrary timestamp (a date... and perhaps time), and for only files created/modified after this time to be downloaded (e.g. the approximate time for the creation of my latest archive). I am envision it as based on the -N option; except that rather than looking on the time-stamp - or the size or even the existance - of a local file, it would only compare the remote file's timestamp to the supplied timestamp - and download if the remote file was newer. Of course, it would probably be h*** of a lot worse to program than just rewriting the -N option. :-) It would have to parse links in HTML-files (HTML) or traverse directories (FTP). Usually it would be used when no local mirror existed, and then creating a mirror of just files made after a certain time (it would of course have to create a dir-structure containing directories also older than the specified time, but no older files). However being able to use it (a specified time) together with the -N or --mirror option, may also be useful when updating a local mirror (though I can't actually see when); so perhaps it should be an option to be used in *companion* with -N (rather than instead of -N)... or at least let it be *possible* to use it together with -N and --mirror as well as by itself. -Koppe
