In Linux, there are hundreds of commands and they can become quite difficult to keep track of. So, sometimes you might not be able to remember one when you need it. The apropos command in Linux can be used for situations just like this.

dd command in Linux with examples
Linux considers anything stored on a file system as files, even block devices. This means commands such as the dd command in Linux can be very handy in many situations, as it can be used to convert and copy files in the terminal, backup disks, or wipe data. The dd command is just as fundamental as it is useful, as it’s ready to use even on the most basic installations of Linux distros.
du command in Linux with examples
On any operating system, the files on your hard disk take up a certain amount of space. In Linux specifically, you can view how much space that these files take up in the command line terminal by using the du command. The du command (the name is shortened from “disk usage”), as the name implies, will simply display, in its output, the amount of disk space being used by a specified file or directory.
csplit command in Linux with examples
In Linux, we can employ many different methods for making text file management more convenient and fluid. The csplit command in Linux is a perfect example of how we can make text files a lot easier to maintain.
Add character to the beginning of each line using sed
The sed command in Linux can be used to do many types of text manipulation. In this tutorial, you’ll learn how to add a character to the beginning of every line using sed. Check out the examples below to see how.
C++ code on how to read characters from a file
This tutorial will show you a small example of C++ code on how to read a characters from a file, as well as to count the number lines that any particular file consist of. We will be creating the script and compiling the C++ on a Linux system. All distros will work the same, provided you have the G++ compiler installed, which we will cover as well.
at command in Linux with examples
In Linux, you can automate many processes using various commands. You can even automate the process of running those commands. You can use the at command to run commands at a specified point in the future or it will only run these commands once. You can specify the time using key words like “tomorrow,” next week,” etc.
bc command in Linux with examples
Most users naturally think of a calculator on their computer as a GUI application, or something that is accessed directly from the desktop. But it’s also possible to use the bc command in Linux to run calculations through the command line terminal. bc is an acronym for “basic calculator.”
cal command in Linux with examples
Most users naturally think of the calendar on their computer as a GUI application, or something that is displayed directly from the desktop. But it’s also possible to use the cal command in Linux to view the calendar through the command line terminal.
cksum command in Linux with examples
Transferring files is a common activity you’ll frequently engage in, whether you are using Linux or any other operating system. Typically, this will go pretty smoothly, as this process is not very complex for computer systems. But file corruption can occur in some instances. The cksum command in Linux helps us verify file integrity and weed out corrupted downloads and file transfers.
