If we change the default behavior, we need an option in wgetrc to turn back on the old one. 8-(
wget doesn't overwrite existing files by default anyways. Instead it appends a suffix .1, .2 etc to the newly downloaded file. wget also prints the file name it used. So IMO it's perfectly fine and useful for wget to take the server provided file name by default. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg)
