The ls command in Linux is one of the most essential commands that every Linux user should know. If you’re a beginner to using the command line, ls is probably the first command you should try to learn. ls is short for list, and is used to list the files in your present working directory or some other directory if you specify one.
Commands
Encrypting and Decrypting Files and Directories on Linux Using mcrypt command
Encryption is a crucial aspect of securing sensitive information on your Linux system. One of the tools you can use for this purpose is mcrypt, which provides symmetric encryption and decryption capabilities. This guide will walk you through the process of using mcrypt to encrypt and decrypt files and directories on Linux, covering a range of options and examples.
mount command in Linux with examples
We can use the mount command in Linux to attach file systems and removable devices such as USB flash drives. The default file system for most Linux distributions is ext4. We can also dismount file systems with the unmount command.
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.

Locate vs find: What is the difference
If you need to search for one or more particular files, Linux systems have a few powerful methods for locating them, such as the find and locate commands. Both of these commands have the same purpose, but they use a different methodology to find files. Searching for a file with a specific name can be done, but you can also search for files that follow certain naming patterns.
How to use xclip on Linux
The xclip tool can be used to interact with the system clipboard from the command line. This can come in handy in instances where you want to send information directly to the user’s clipboard, without requiring that they highlight and copy the text themselves. It also works in the other direction, so the xclip command can check the contents of the clipboard.
How to export repositories with the git-daemon
Git is probably the most used version control software in the world. Free and open source, it was created by Linus Torvalds, and it is the base of services provided by web platforms like Github and Gitlab. In a previous article we discussed the git workflow basics,
Pax command examples on Linux
pax is an archive utility somewhere between cpio and tar. This is just because it is independent of the specific archive format, and supports a wide variety of different archive formats. It can perform simple tasks as creating a compressed archive of a selected directory or it can as much easily create a daily incremental backup.
How to list and manage files attributes on Linux
When using Linux we have many ways to manage access to resources: the most basic one is by setting the appropriate UGO/RWX permissions on files and directories. In some occasions we may also want to make use of the setuid, the setgid and the sticky bit. Furthermore, we can use ACLs (Access Control List) in order to achieve an higher level of granularity or implement Mandatory Access Control security such those based SELinux or AppArmor.
In addition to the strategies mentioned above, on most filesystems we can manipulate a set of “attributes” in order, for example, to make a file immutable.
Linux Cheat Sheet
In this tutorial, we will list various practical Linux commands to be used only as a reference guide and by experienced Linux users. Not all Linux commands will be available on your system by default so consider installing the relevant package before use.
Linux xxd command explained
Once a program has been compiled, it is not easy to get a peek at the source code or to manipulate its behavior. But there is one thing we can do, which is look at the hexadecimal values inside the binary files. We can also make changes to the data and compile it back to a binary file. This will sometimes reveal information about a file, or allow us to modify its behavior if we can manage to edit the right bit.
