While it’s one of the best tools for examining performance on Linux, htop still requires some explanation before you’ll be ready to take advantage of all the data it displays. It’s an excellent tool, but you need to understand the coloring scheme, how to scroll up and down through the processes displayed, and how to change… Continue reading Using Htop To Check Performance On Linux | Network World

Removing Duplicate Characters From A String On Linux With Awk | Network World
The awk command can make it easy to remove duplicate characters from a string even when those characters aren’t sequential, especially when the process is turned into a script. First, the awk command that we’ll be using starts by running through each letter in the string. In a more common command, you might see awk… Continue reading Removing Duplicate Characters From A String On Linux With Awk | Network World
Using Clamav To Detect Viruses On Linux | Network World
One popular and easy-to-use tool for detecting virus infections on Linux systems is ClamAV. It’s open source and free, and runs on many Linux systems, Ubuntu and Fedora included. In this post, we’ll take a look at how to install and use the tool on Ubuntu, Linux Mint, and related systems. Installing ClamAV on Linux… Continue reading Using Clamav To Detect Viruses On Linux | Network World
Using Strace And Ltrace To Help With Troubleshooting On Linux | Network World
Both strace and ltrace are powerful command-line tools for debugging and troubleshooting programs on Linux: Strace captures and records all system calls made by a process as well as the signals received, while ltrace does the same for library calls. If a program acts differently than you expect, you can use these tools to see… Continue reading Using Strace And Ltrace To Help With Troubleshooting On Linux | Network World

Linux Foundation Works Toward Improved Data-Center Efficiency | Network World
Organizations exploring the use of data-processing units (DPU) and infrastructure processing units (IPU) got a boost this week as the Linux Foundation announced a project to make them integral to future data-center and cloud-based infrastructures. DPUs, IPUs, and smartNICs are programmable networking devices designed to free-up CPUs for better performance in software-defined cloud, compute, networking,… Continue reading Linux Foundation Works Toward Improved Data-Center Efficiency | Network World
Open-Sourced Tool Speeds Up Linux Scripts Via Parallelization | Network World
Researchers have open-sourced pa.sh (also called pash), a tool that can dramatically speed up Linux scripts by using parallelization, saving time and without risk of introducing errors. The process of parallelization first examines a script for code that can be run separately and independently, so not all scripts can benefit from the tool. But when… Continue reading Open-Sourced Tool Speeds Up Linux Scripts Via Parallelization | Network World
The Linux Fold Command Breaks Up Text, Drives Loops | Network World
The Linux fold command enables you to break a string of characters into same-size chunks, but it can also be used to provide a series of characters or strings to drive a loop. This post reviews the basic command and then demonstrates how you can use it to loop through the characters or strings that… Continue reading The Linux Fold Command Breaks Up Text, Drives Loops | Network World
