WHAT IS IT

This is a simple set of scripts that allow for the creation of temporary email addresses that will expire after a certain amount of time. These addresses can be used for things like signing up to website one isn't sure about or to test certain products using an email address that will go away (forcing rejects back to the sender).

Initially, this will simply generate email addresses in the following format.

<word>.<random hex string>@<domain>

For example.

chard.6d06@3cx.org

These email addresses will be added as aliases to the system's /etc/aliases file. Each transient address and its expiration date will be tracked via a mechanism outside of the /etc/aliases file.

Installation instructions and the scripts can be found after the break.

ss3b is a simple backup system I put together to make incemental backups sane for me. You can read more about it on github, but effectively it makes use of incremental features of tar, some encrpytion, the AWS CLI tool, and some bash. You feed it a config and a list of directories to routinely back up, drop it in a crontab, and forget about it.

There are quite a few systems out there, but my goal was to use as many "default" system tools as possible. It does use a bit of bash specific code, but hey... it's bash.
