In Linux, command substitution allows a user to use the output of a command as an argument for other commands. Here you can substitute all commands that can write standard output. Moreover, you can use the command substitution to create a shell script and save the command's output as a variable. Some of the output consists of multiple lines, so the output may not appear in the same pattern when you perform command substitution. When you don't use the proper shell variable, the output shows in a single line, i.e., without preserving the linebreaks. In this tutorial, we will look ... Read More

The dutree is an open-source and free command line tool in Linux that lets you analyze disk usage and display the output in a colored format. This command combines two well-known Linux commands, the durep (generates disk usage report) and the tree (lists the contents of a directory in tree format) commands, and their attributes, written in the Rust language. Whenever you use this command to determine disk usage, it displays the result in a tree-like format. The dutree command is mainly used to see which directories and files take up the most space on the hard disk and lists ... Read More

There are several benefits to using operating system-based virtualization. You can run multiple operating systems on the same physical hardware. This can be useful for testing different operating systems, running legacy applications, or saving space on your computer. Another advantage is that it can improve performance. By isolating each operating system from others, virtualization software can prevent conflicts and improve overall system performance. It creates a layer of abstraction between the hardware and the operating systems. The virtualization software is installed on the host operating system. It manages this layer of abstraction and allows guest operating systems to access ... Read More

Introduction Integrity of files and directories is an essential aspect of system security and data protection. File integrity refers to the accuracy and completeness of the information stored in a file, while directory integrity concerns the structure, permissions, ownership, and attributes of directories. When files or directories are tampered with or corrupted, they can cause critical errors, data loss, or even compromise system stability. Therefore, checking file and directory integrity is crucial for ensuring system reliability and preventing security breaches. Installing AIDE on Linux Requirements for Installing AIDE Before installing AIDE, it is important to ensure that the system meets ... Read More

Introduction Monitoring the performance of a Linux system is essential to ensuring that it is operating optimally. One of the key factors in determining the performance of a system is CPU utilization. CPU utilization refers to the percentage of time that the processor spends executing instructions from various processes and applications on the system. In Linux, there are numerous tools available for monitoring CPU utilization, but using command line tools provides a quick and efficient way to check this metric. Basic Command Line Tools for Checking CPU Utilization When it comes to monitoring CPU utilization with the command line in ... Read More

Introduction Monitoring CPU temperature on a Linux system is essential for maintaining optimal performance and preventing hardware damage. The CPU (central processing unit) is the brain of your computer, and it generates heat as it processes data. Over time, this heat can cause your CPU to slow down or even fail altogether. By monitoring your CPU temperature, you can identify potential issues before they cause permanent damage to your system. Understanding CPU Temperature on Linux CPU temperature is a measure of how hot the processor is running and is an important metric for computer performance. The faster a processor works, ... Read More
