Linux command line / Terminal offers a quick and simple way to do most things. Let’s say that if we want to view contents of a directory and all the sub directories within it quickly all in one go, here is how to do it :
1. Open Terminal and type the path of the directory whose contents (along with the contents of subdirectories and their subdirectories and so on ) after ls command and the R switch so that it looks like this :
In the example shown below, there is a directory named colors in the home folder (/home/avp/colors). Within this directory are sub directories named blue, green and red. Within each of these sub directories are files named bluecolor.txt, greencolor.txt and redcolor.txt
All of this is simply found out by typing :
This will quickly list everything within that directory and the directories within it and so on. Commonly it is known as recursive listing and is pretty handy when trying to search for a specific file or a directory.
