Wget with 304 check

curlwget

Is it possible to use wget to download a file, if only it's not modified?

I'm thinking about the HTTP status code 304, but I don't know how to instruct wget to add a If-Modified-Since header, or something similar.

Is it even possible? I can use other tools to do that as well

Basically, it's :

wget -N http://www.some-url.com/folder/

I think these switches will do what you want with wget:

   -A acclist --accept acclist
   -R rejlist --reject rejlist
       Specify comma-separated lists of file name suffixes or patterns to 
       accept or reject. Note that if any of the wildcard characters, *, ?,
       [ or ], appear in an element of acclist or rejlist, it will be 
       treated as a pattern, rather than a suffix.

   --accept-regex urlregex
   --reject-regex urlregex
       Specify a regular expression to accept or reject the complete URL.

Example

$ wget -r --no-parent -A 'bar.*.tar.gz' http://url/dir/
