Creating and executing a .jar file in Linux is a simple process that combines the compilation of Java source code and the packaging of class files and resources into a single file. With the terminal, you can easily compile your code, create a .jar file, make it executable, and run your Java application with ease. The JAR format, also known as the Java ARchive, offers a flexible and efficient way to package Java class files, resources, and metadata into a single, platform-agnostic file. The purpose of this format is to simplify the distribution and deployment process for Java runtimes, while ... Read More
To create a bootable USB drive from an ISO file in Linux, we find it useful when installing a new operating system or running a live environment without affecting my existing system. It's also an excellent option when my computer lacks a CD/DVD drive, as USB drives are more common and easier to use. To start the process, we use the "lsblk" command to find the device name of the USB drive and then download the ISO file. we then mount the ISO file and use the mount and dd commands to copy its contents to the USB drive. When ... Read More
Many times while taking back up of data from one location to another or configuring software, we need to maintain the same level of ownership and permission of the files. Creating those permissions and granting ownership to individual files can be error prone of done by typing commands for each of the files. So we use some arguments with the chown and chmod commands.OwnershipWe use the –-reference swiych in the chown function to specify the ownership cloning from the source file to the target file.Syntaxchown --reference=source_reference_file target_fileIn the below example we have a source file whose ownership gets cloned to ...

As Linux users and administrators, we are responsible for managing services on remote Linux servers, which could include web servers like Apache or Nginx, or database servers like MySQL or PostgreSQL. To effectively manage these services, we need to have a strong understanding of the underlying system and service manager for Linux - systemd. Systemd is a robust and feature-rich system and service manager designed for Linux-based operating systems. It takes care of managing the initialization and termination of services, tracks system processes, and oversees system resources. It is widely acquired as the default system and service manager in many ... Read More
Introduction Knowing the efficiency of algorithms is crucial in the domain of computer science and programming as it aids in creating software that is both optimized and fast−performing. Time complexity is an important notion in this context since it measures how the runtime of an algorithm changes as the input size grows. The commonly used time complexity class O(n) signifies an association of linearity between the input size and execution time. Definition Algorithmic complexity within computer science is the assessment of the resources, such as time and space utilization, required to operate an algorithm depending on its input size. ...
