httrack allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site’s relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads.

The system wide configuration file.



Is being used if you defined in /etc/httrack.conf the line path ~/websites/#


Errors/Warnings are reported to hts−log.txt by default, or to stderr if the -v option was specified.


These are the principals limits of HTTrack for that moment. Note that we did not heard about any other utility that would have solved them.

- Several scripts generating complex filenames may not find them (ex: img.src=’image’+a+Mobj.dst+’.gif’)

- Some java classes may not find some files on them (class included)

- Cgi-bin links may not work properly in some cases (parameters needed). To avoid them: use filters like -*cgi-bin*
