`tmux` is a  *terminal multiplexer*, meaning that it allows multiple terminals (sessions) to run in the same window.

This is especially useful on a server, where you can use it to persist the state of your work enviornment.

- https://github.com/BurntSushi/ripgrep#quick-examples-comparing-tools

- our bet is on `ripgrep` -- it currently seems to be the best thing out there

# Closing Thoughts

Unix seems like a good investment

We hope so was this class

If you would like to learn more, there are followups at Matfyz:
- Unix Administration
- Linux "principles and means"
- Advanced Unix Administration
- (Embedded) Linux Programming

If you liked the experience and would like to share it with the next year's
batch, please do **talk to us**.

_That is how we became TAs, too._
