I'm writing "The Impostor's Guide To The Shell". My theory is that reading popular open-source codebases, and Googling stuff you don't understand until you grok it, is a great way to overcome impostor's syndrome. The goal is to take a reader from thinking "Maybe a 10x engineer could understand that library, but I never could..." to "Oh, that's all it does?".

The guide covers things like:

- shebangs

- exit codes

- parameter expansion

- file permissions

- how to look up docs via "man" and "help"

- And a lot more.

The codebase I'm starting with is a Ruby version manager (written in bash) called RBENV. I've published it onto a platform called HelpThisBook.com, a platform to help authors get feedback from early readers (co-created by Rob Fitzpatrick, author of "The Mom Test", "Write Useful Books", etc.). Instructions on how to leave feedback should be given when you open the link below.
