As a web developer, you often get asked to update and upgrade existing websites, and to fix issue with existing websites.
More often than not, its easier to do this on a local copy of the website than on a live remote server.
There are various ways to copy an entire website, but sometimes when a site isn’t very well designed (eg with absolute rather than relative links) this can take quite a bit of sorting out.
This is where a tool called Httrack comes in every handy. It’ll download the website for you over http (so you don’t even need ftp login details) and convert all links to relative links.
Its available for both Windows and Linux, and is in the repositories for Ubuntu.
