Introduction

Wget command stands for 'web get,' is a versatile and free command-line tool for downloading files from the internet. It operates seamlessly in the background, allowing users to disconnect from the system while it efficiently fetches files non-interactively.

Wget is a free utility for non-interactive downloading of files from the web. It supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.

This guide will dissect each command, providing a detailed understanding of Wget's capabilities.

Exploring Wget's Command-Line Options

Let’s dive deeper into the wget’s command line options. 

Option Description
-r, --recursive Enables recursive downloading of files and directories.
-np, --no-parent Restricts downloading to the current hierarchy.
-P, --directory-prefix=PREFIX Sets the directory where files are saved.
-A, --accept=LIST Downloads only files with extensions in the list.
-R, --reject=LIST Ignores files with extensions in the list.
-nc, --no-clobber Skips downloading if a file with the same name exists.
-N, --timestamping Downloads files only if newer than the local copy.
-q, --quiet Suppresses output, except for errors and download bar.
-O, --output-document=FILE Specifies the output file name.
-U, --user-agent=AGENT Sets the User-Agent header for the HTTP request.
-h, --help Displays help information about wget options.

-v / --version

Description: This option is used to display the version of Wget installed on your system, providing insight into the specific build and features available to you.

Syntax:

wget -v

-h / --help

Description: This option is used to display a help message, listing all the command-line options available with Wget. It serves as a quick reference guide for users.

Syntax:

wget -h

-o logfile

Description: This option is used to log all messages from Wget to a specified logfile. It is useful for saving a record of the download process, which can be reviewed later for information or troubleshooting.

Syntax:

wget -o logfile [URL]

-b / --background

Description: This option sends the download process to the background upon initiation. It allows the user to continue with other tasks without having to wait for the download to complete.

Syntax:

wget -b [URL]

-a logfile

Description: This option appends messages to a specified logfile without overwriting the existing content. It is useful for maintaining a continuous log over multiple Wget operations.

Syntax:

wget -a logfile [URL]

-i file

Description: This option reads URLs from a specified file, allowing for batch downloading. It is particularly useful when dealing with multiple downloads, keeping the command line uncluttered.

Syntax:

wget -i file

-t number / --tries=number

Description: This option sets the number of retries for a download to a specified number. If a download fails, Wget will retry the specified number of times before giving up.

Syntax:

wget -t number [URL]

-c

Description: This option is used to resume a partially downloaded file. If a download is interrupted, Wget can pick up where it left off, saving time and bandwidth.

Syntax:

wget -c [URL]

-w seconds

Description: This option sets the interval between retrievals to a specified number of seconds. It is recommended to use this option to reduce the load on the server and to adapt to network errors or downtimes.

Syntax:

wget -w seconds [URL]

-r / --recursive

Description: This option enables recursive retrieval of websites. Wget will follow links and download entire directory structures, mirroring the layout of the original site.

Syntax:

wget -r [URL]
