Command line tricks: Globbing basics
Sat Feb 24 2024When working with files in the command line, you don't always want to write full file names. Maybe you are working on a group of files that has file names with a given patterns, like log files (e.g, log011023.txt)? Or maybe you want to filter out files that don't fit a given pattern? Or maybe your use case is just picking out shell scripts that starts with the letter P?

Read more..The joy and wonders of browsing the web from the command line - A short introduction to Lynx

Sat Oct 02 2021In this article I will introduce you to the command line, or bash equivalent ones at least.
