GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the two most widely-used Internet protocols. It is a non-interactive commandline tool, so it may easily be called from scripts, cron jobs, terminals without Xsupport, etc.

Wget has many features to make retrieving large files or mirroring entire web or FTP sites easy, including:

• Can resume aborted downloads, using REST and RANGE
• Can use filename wild cards and recursively mirror directories
• NLS-based message files for many different languages (note: I did not compile NLS support in this version)
• Optionally converts absolute links in downloaded documents to relative, so that downloaded documents may link to each other locally
• Runs on most UNIX-like operating systems as well as Microsoft Windows
• Supports HTTP and SOCKS proxies
• Supports HTTP cookies
• Supports persistent HTTP connections
• Unattended / background operation
• Uses local file timestamps to determine whether documents need to be re-downloaded when mirroring
• GNU wget is distributed under the GNU General Public License.
