Linux Tutorials
As you start spending more and more time working on the Linux command line, you tend to learn utilities that aren’t very frequently used. Once such tool is sum, which only offers two features: display checksum and block count for input files. In this short tutorial, we will quickly discuss the basics of sum using some easy to understand examples.
Sometimes, you come across a command line tool that offers limited functionality on its own, but when used with other tools, you realize its actual potential. Once such tool is seq, which prints a sequence of numbers.
Most of the Linux commands you encounter do not depend on other operations for users to unlock their full potential, but there exists a small subset of command line tool which you can say are useless when used independently, but become a must-have or must-know when used with other command line operations. One such tool is yes, and in this tutorial, we will discuss this command with some easy to understand examples.
This guide shows how you can install and use incron on a Debian 9 (Stretch) system. Incron is similar to cron, but instead of running commands based on time, it can trigger commands when file or directory events occur (e.g. a file modification, changes of permissions, etc.).
As some of you might already know, an object or executable file in Linux consists of several sections (like txt and data). In case you want to know the size of each section, there exists a command line utility – dubbed size – that provides you this information.
