We're back after a (planned) lengthy hiatus! In this instalment, Bart teaches us how to protect our secrets while working in the Terminal. Secrets can include passwords, API keys, and any other sensitive information you'd like to protect. Without the tools Bart teaches us, any secrets you type into the Terminal will be in your history file in plain text, and with AI, possibly hoovered up as training data.
You can download the free Taming the Terminal book at podfeet.com/tttbook. All of the versions are up to date with the new chapter, except Apple Books. As of 18 December 2025, the one in Apple Books is "in review" with the new chapter. Hopefully, by the time you look for it, they will have deemed that chapter worthy of inclusion. I just noticed that it's available in Apple Books in 51 countries! The book has 4.9 stars with 30 reviews!
