Wget Command Syntax
The fundamental syntax of Wget is:
$ wget [option] [URL]
First, verify whether or not the wget utility is already put in or not in your Linux field, utilizing the next command.
$ rpm -q wget [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux] $ dpkg -l | grep wget [On Debian, Ubuntu and Mint]
Set up Wget on Linux
If Wget isn’t put in, you may set up it utilizing your Linux system’s default package deal supervisor as proven.
$ sudo apt set up wget -y [On Debian, Ubuntu and Mint] $ sudo yum set up wget -y [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux] $ sudo emerge -a net-misc/wget [On Gentoo Linux] $ sudo pacman -Sy wget [On Arch Linux] $ sudo zypper set up wget [On OpenSUSE]
The -y possibility used right here is to forestall affirmation prompts earlier than putting in any package deal. For extra YUM and APT command examples and choices learn our articles on:
1. Obtain a File with Wget
The command will obtain a single file and retailer it in a present listing. It additionally exhibits obtain progress, dimension, date, and time whereas downloading.
