How to get a fancier bash prompt PS1 inside a docker container

Today I wanted to make a recording of me running some commands inside a docker-container.

❯ docker-compose run app bash
root@e9bb2af4dc11:/usr/local/go/src/example.com/dev/project#

Needless to say it looked a bit bland with no colors and a long prompt that prevents me from recording a small terminal and show the full commands I'm

Story: Writing Scripts with Go

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
