Wget Commands Cheatsheet

Wget Command Examples

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

GNU 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
  • 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 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.

The source code for GNU Wget can be found on http://ftp.gnu.org/gnu/wget/ [via http] and ftp://ftp.gnu.org/gnu/wget/ [via FTP]. It can also be found on one of FTP mirrors.

You can store number of URL’s in text file and download them with -i switch.

Resume download

In some cases ( when you download huge files ) your download can be interrupted for some reason. You can resume your download with -c switch. If you start your download without specifying -c switch wget will add .1 extension at the end of file and start a new download. It’s a good practice to add -c switch when you download big files.

# wget -c http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

 .1 in file name

When you start a download without -c switch wget adds .1 at the end of file and start with fresh download. If .1 already exist .2 append at the end of file.

# wget  http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

Download files in background

With -b switch you can send download in background immediately after download start and logs are written in /wget/log.txt file.

# wget -b /wget/log.txt http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

Continuing in background, pid 3550.

Limit download speed

With Option –limit-rate=100k, the download speed limit is restricted to 100k and the logs will be created under /wget/log.txt as shown below.

# wget -c --limit-rate=100k  /wget/log.txt http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

Restricted FTP and HTTP downloads

With Options –http-user=username–http-password=password & –ftp-user=username–ftp-password=password, you can download password restricted HTTP or FTP sites as shown below.

# wget --http-user=username --http-password=password http://some-network.net/some-file.txt
# wget --ftp-user=username --ftp-password=password ftp://some-network.net/some-file.txt

Increase Retry Attempts.

You can increase the number of retry attempts using ‘–tries‘ switch. By default wget command retries 20 times to make the download successful.

This switch becomes very useful when you have internet connection problem and you are downloading a large file

# wget --tries=75 http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

Redirect wget logs

We can redirect the wget command logs to a log file using ‘-o‘ switch.

#wget -o download.log http://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz

Download.log file will be created in the user’s current directory.

Setting Download Quota

We can force wget command to quit downloading when download size exceeds certain size using ‘-Q’ switch

# wget -Q10m -i download-list.txt

Note: quota will never affect downloading a single file.

Download Entire Website

If you ever need to download an entire Web site, ( for off-line viewing, analysis, inspection or vulnerability assessment)  wget can do that for you

$ wget --recursive --no-clobber --page-requisites --html-extension --convert-links --restrict-file-names=windows --domains some-site.com --no-parent www.some-site.com

This command downloads the site www.some-site.com.

The options are:

  • –recursive: download the entire Web site.
  • –domains some-site.com: don’t follow links outside some-site.com.
  • –no-parent: don’t follow links outside the directory /.
  • –page-requisites: get all the elements that compose the page (images, CSS and so on).
  • –html-extension: save files with the .html extension.
  • –convert-links: convert links so that they work locally, off-line.
  • –restrict-file-names=windows: modify filenames so that they will work in Windows as well.
  • –no-clobber: don’t overwrite any existing files (used in case the download is interrupted and
    resumed).

Reject file types while downloading.

When you are planning to download full website , then we can force wget command not to download images using ‘–reject’ switch .

# wget --reject=png www.some-site.com

Download Only Certain File Types

You can use this under following situations:

  • Download all images from a website
  • Download all videos from a website
  • Download all PDF files from a website
$ wget -r -A .pdf http://some-site.com/
