yum update command in Linux
yum updateThe command (modified as yellow-dog updater) is an open source command used in Linux. Using yum update, we can easily install, update, and remove software packages on Linux systems.
Let us understand how to use yum command for different purposes in Linux. Before using yum update command, we need to install yum update package using following command.
Step 1:
$ sudo apt-get update -y
Step 2:
$ sudo apt -y install yum
After running the above command, the yum update package will be installed on your Linux system.
Install the package using the yum command
If we want to install a package called Firefox, we can do so using the yum command. The following yum command will automatically find and install the required Firefox package.
$ yum install Firefox
The above command will ask for confirmation from the user before installing the Firefox package on the system. If we want to avoid this and automatically install the package without asking for confirmation, we need to use the -y option as shown below.
$ yum -y install firefox
Remove packages using yum command
We can remove any package using yum command in Linux. If we want to remove Firefox package that we installed, we use the following command.
$ yum -y remove firefox
The above command will remove the Firefox package including all its dependencies. We have also used the -y option here.
Run this command without asking for confirmation before removing the package.
Update packages using yum command
We can also use yum command to update any package in Linux.
For example, we have a package called MySQL and we want to update it to the latest version. We can update it to the latest version using the following command. e We installed the Firefox package, we use the following command.
$ yum update mysql
Get information about any package using yum command
Using yum command, we can also get information about any package before installing it.
For example, if we want to install Firefox package on Linux, let’s first learn about the package. We can get information about Firefox package by running the following command.
$ yum info Firefox
The difference between yum update and yum upgrade
yum updateThe yum upgrade command updates all installed packages to the latest versions available in the repository. The yum upgrade command does the same.
The difference between these commands is that when we use yum upgradethe remove command, it removes all obsolete packages from the system after installing the packages whereas yum updateremove does not remove obsolete packages from the system after installing the packages.
