Linux commands cheat sheet
The command line terminal in Linux is the operating system’s most powerful component. However, due to the sheer amount of commands available, it can be intimidating for newcomers. Even longtime users may forget a command every once in a while and that is why we have created this Linux cheat sheet commands guide.

VirtualBox increase disk size on Linux
In this tutorial you will learn how to increase disk size on VirtualBox. One of the great things about installing an operating system into a virtual machine is that we can easily change the machine’s CPU utilization limit, its memory usage, and the amount of hard drive space it has. With VirtualBox, all of these hardware specifications can even be changed long after the virtual machine is created.
Man command in Linux with Examples
The Linux operating system is absolutely brimming with different commands to use. Even with a fresh Linux installation, you can open a command line terminal and have instant access to hundreds of commands. This is why we have man command in Linux.
There’s only one problem, which is that you need a little background information about how to use each command.
NFS vs SAMBA vs CIFS
NFS, SAMBA, and CIFS are three different terms that get thrown around a lot whenever someone mentions file sharing between two or more systems. But, do you know what these three implementations do, and how they do it differently from one another? For some reason these technologies remain in a shroud of mystery to even some seasoned system administrators.
How to connect to Docker container via ssh
After installing Docker on Fedora, AlmaLinux, Manjaro, or some other distro, it’s time to install more containers. Once you have a Docker container up and running on a Linux system, one of the things you’ll likely need to do is run commands inside the container. This allows you to use the container similarly to how you would a physical machine, except that Docker has done most of the setup legwork for us already.
There are already two commands available that allow us to run commands on a Docker container. The first one is docker exec, and the second command, which allows us to attach to a running container, is docker attach. These commands usually suffice, but you may find yourself in a scenario where you’d prefer to use SSH to connect to the Docker container and manage it.
Not all Docker containers are provisioned to run SSH. Normally, Docker containers are very lightweight and only programmed to do one thing. However, some Docker containers will allow SSH, and this can make management of the container much easier. In this guide, we’ll see how to connect to a Docker container via SSH from the host system on Linux command line.
In this tutorial you will learn:
- How to connect to a running Docker container via SSH
Linux – Reset password expiration, age and history
User management is an important part of Linux administration, so it’s essential to know about all the user accounts on a Linux system. Some common user administration tasks are to list users, disable a user account, or create and modify user accounts.
In this guide, we will be focusing on managing user passwords. It’s good security practice to force users to change their password every once in a while by setting passwords to expire. In the examples below, you’ll see how to reset a user’s password, set their password to expire (either instantly or in the future), and see the age of a user’s password. We’ll also see how password changes can be seen in log files, giving us some insight into user’s password change history.
In this tutorial you will learn:
- How to set a user’s password to expire
- How to see the age of a user’s password
- How to see password changes in log files
Squid proxy configuration tutorial on Linux
Squid is a robust proxy server that supports caching for protocols like HTTP, HTTPS, and FTP. It has the ability to speed up web requests by caching frequently accessed websites, and serving that cache to requesting clients. This is a great way for networks to reduce bandwidth consumption and provide snappier response times for web browsing.
In this guide, we’ll go over the step by step instructions to download, install, and configure Squid proxy on a Linux system. Follow along with us to get it setup on your own system, which can either provide caching just for yourself or all the way up to an entire organization of computers.
In this tutorial you will learn:
- How to download and install Squid proxy on major Linux distros
- How to configure Squid proxy
- How to configure a browser to use Squid proxy
How to rename multiple files on Linux
Renaming files on Linux systems is usually handled by the mv (move) command. The syntax is just mv old.txt new.txt. Simple enough, but what if we have multiple files that need to be renamed at once, even hundreds of them? The default mv utility can’t handle renaming more than one file unless we do a bit of scripting. There are also other utilities we can install to solve the problem, like rename and mmv.
In this guide, we’ll show you how to use the mv command as well as the rename and mmv tools to rename multiple files on your Linux distro. We’ll go over several examples so you can understand the syntax and how to use each method.
In this tutorial you will learn:
- How to rename multiple files at once with mv command
- How to install rename on major Linux distros
- How to install mmv on major Linux distros
- How to use mmv, through command examples
- How to use rename, through command examples
