It would be good to point out that extensions are actually kind of arbitrary. There are so many esoteric extensions out there; no program, including the. Introduction. If you do not have much experience working with Linux systems, you may be overwhelmed by the prospect of controlling an operating system from the command line. In this guide, we will attempt to get you up to speed with the basics. This guide will not cover everything you need to know to. For short files: cat . directly shows a text file in the terminal. For longer files: less . lets you scroll and search ( / text to search Enter ) in the file; press q to exit. e.g. cat /home/john/RESULTS.txt less /home/john/RESULTS.txt.
