How to write comments in Bash Scripts
Well you have written an awesome Bash script. It works perfectly and perhaps there is no need to add new functionality. Well, maybe not for now, at least! At this stage you are happy with the script. However, after few months you reopen your bash script again to add new feature and you get a headache to figure out on how the script actually works. Hence, you need to spend additional energy and time before you can actually start editing the script in order to add new feature.

How to install deb file in RHEL 8 / CentOS 8 Linux
There may come a time when that package you want to install in RHEL 8 / CentOS 8 is simply not available as a RPM file. The alternative is to download the source and compile it yourself, or – alternatively – generate a RPM file from that source code later on.
But there is another way. Given the fact that Debian-based distributions have way more users than RPM-based ones, the number of available packages in their repositories is greater. Chances are you will be able to find a DEB file for that package you want. Here is how to install that DEB file in RedHat Linux with the help of a small utility called alien.

How to install packages on RHEL 8 / CentOS 8 Linux System
All modern linux distributions organize software in packages which contain applications binaries, files, metadata and information about the package dependencies, possible conflicts with other packages etc. The core Rhel package manager is called rpm itself, and it is the tool used also by dnf, the higher level package manager, which is capable to manage dependencies. A relatively recent technology , flatpak, let us install also sandboxed applications together with their runtimes.
In this tutorial you will learn:
- The three main ways to install a package using rpm

RHEL 8 / CentOS 8 change hostname
A hostname is the label or name linked to a device on a network. Its main purpose is to recognize a device on a specific network or over the internet. There are three different hostname types:
- Static – Most of the time you will be interested in this type of hostname which is defined by user and the
/etc/hostnameconfiguration file. - Transient – This type of hostname is defined within kernel space and by default it is set to be the same as the static hostname. Transient hostnames can be set/updated by DHCP or mDNS at runtime.
- Pretty – Pretty hostname allows for additional characters as per UTF8 character set hence serving rather only for presentation purposes. The pretty hostname also allows to include spaces.
This article will explain how to change or set hostname on RHEL 8 / CentOS 8 Linux server or workstation. To change hostname you will use the hostnamectl command.
In this tutorial you will learn:
- How to change the static hostname.
- How to change the transient hostname.

Easy way to create a Debian package and local package repository
This article describes a simple way to create a home made debian package and include it into a local package repository. Although we could use an existing Debian/Ubuntu package, we will start from scratch by creating and packaging our own trivial application. Once our package is ready, we will include it into our local package repository. This article illustrates a very simplistic approach, however it may serve as a template in many different scenarios.
In this tutorial you will learn:
- How to create a trivial debian package
- How to create a local debian repository
- How to add the repository to the list of software sources
