Differences between yum and rpm!

A Detailed thread 👇

1/ A major difference between #yum and #rpm is that yum is a package manager, while rpm is a package format. Yum uses rpm as its underlying packaging format, but adds additional functionality to manage package dependencies.

2/ Another key difference between #yum and #rpm is that yum is capable of automatically resolving dependencies between packages. For example, if you install a package with yum that requires another package, yum will automatically install that package for you.

3/ #yum also provides additional functionality like package groups, which allow you to install multiple packages at once. You can specify a group of packages to install, and yum will automatically install all of the packages in the group.

4/ In contrast, #rpm only manages individual packages. If you want to install multiple packages at once with rpm, you need to specify each package individually.

5/ Additionally, #yum can download and install packages from remote repositories, making it easy to manage software on multiple systems. Rpm does not have this functionality built-in, and requires you to manually download and install packages.

6/ However, #rpm can be useful for installing packages in situations where you don't have access to a remote repository, or if you want to install a package from a local file. Rpm can be used to install packages directly from a .rpm file on your system.

7/ Finally, #yum is often used on Red Hat-based Linux distributions like Fedora and CentOS, while #rpm is used on a variety of Linux distributions. However, many Linux distributions have now adopted yum as their default package manager.

While #yum & #rpm share some similarities, dey also hv imp diff's. Yum is a pkg mgr dat uses rpm as underlying format & provides add'l functionality like automatic dependency resolution & remote pkg mgmt. Rpm is a standalone pkg format dat canbe useful wen yum isn't available

Here are some practical examples of the differences between rpm and yum: 👇

[1] Package Installation:

Package Installation: When using rpm, you need to manually download the package file, navigate to the directory where the package file is located, and then use the rpm command to install it.
For example:
sudo rpm -ivh package-name.rpm

[1.1] With yum, you can simply use the command:

sudo yum install package-name

Yum will automatically download and install the package, as well as any dependencies that the package needs.

[2] Group Installations: Yum provides the ability to install groups of pkgs.

For example, u can use yum to install the "Development Tools" group, which includes a set of commonly used development tools & libraries:

sudo yum groupinstall "Development Tools"

[2.1] With rpm, you would need to manually download and install each package in the group individually.

[3] Package Removal:

Wen using rpm to remove a pkg, u need to manually specify the pkg name & version.

For eg:
sudo rpm -e pkg-name-version

With yum, u can simply use the cmd:
sudo yum remove pkg-name

Yum will automatically remove d pkg & dependencies dat r no longer needed

[4] Package Verification:

Yum provides the ability to verify d integrity of installed pkgs. Dis can be useful for ensuring dat pkgs hvn't been modified/corrupted.

You can use yum to verify d installed pkgs:

sudo yum verify

Wid rpm, each pkg needs to be verified individually.

Overall, yum provides a more comprehensive package management experience than rpm, with additional features and functionality that can save time and simplify the management of packages and dependencies.
