Redirects

Summary

Redirection assists in redirecting input & output functionalities to the files or folders we want. There are 2 types of redirection:

1. Overwrite Redirection

The > command

This will store/save the output of a command to a file & overwrite existing content of that file.

2. Append Redirection

The >> command

This will redirect the standard output of a command on the left of >> & append it to the end of the file on the right of >>. This will not compromise the existing data of the file it is added to.

Basic command structure

For all descriptions below, the dollar sign indicates that BASH command prompt.

$ [command] > [file name]

$ [command] >> [file name]
