About The Project

hed screencast

hed allows you to manipulate your hosts file from the command-line. By providing safe and easy commands you can add new hosts and aliases to your environment.

This tool was inspired by my students to whom I teach a Basic Cyber Security class. In this class we utilize Hack The Box as a learning platform and most students struggle with editing the hosts file when they get started. To make this easier for them I wrote a tool that gives them a safe means of adding and removing hosts in this file.

The tool is to be used as a regular user, it will elevate privileges when it requires it by calling sudo and respawning the process.

View the current hostsfile

hed show will color print the current hosts file.

hed show


#                    This is a comment	localhost	
::1	localhost	pop-os.localdomain	pop-os

Add a new entry

hed add example.com

Will add the following line to the hosts file.	example.com

Add a subdomain

hed add demo.example.com

Will update the hosts file to add the subdomain to the parent domain as an alias	example.com	demo.example.com

Remove a hostname

hed delete demo.example.com

If it is the primary name , the shortest alias will be chosen as new name for the host entry. If there are no aliases, the entire record is deleted.

hed delete

Will remove the entire record even if there are many aliases defined.


Use the --file parameter to test the features of hed on a file that is not your hosts file.

hed --file test.txt add example.com
