# Ghost

*Your friendly helper with /etc/hosts, written in Go!*

## Features

- Extending existing lines
- Deduplication
- Format check
- `SUID` safe!

## Usage

To add two domain names, `domain1.foo` and `domain2.bar`, for the IP addres `10.0.0.1`:

`./ghost 10.0.0.1 domain1.foo domain2.bar`

The added line will look like this:

```
10.0.0.1        domain1.foo domain2.bar # Added by ghost on 26-10-2023
```

## Notes

The tool is safe to use with the [SUID bit](https://www.redhat.com/sysadmin/suid-sgid-sticky-bit), which is very handy for not entering your password when adding hostnames to your `/etc/hosts` file every time.

While this is very handy for CTFs or platforms like Hack The Box, this is also a big security issue, e.g. if you are on a multi-user machine. **Use with caution!**
