Prompt Engineer

The terminal literacy an AI engineer actually needs.

For prompt & AI engineers. Move around a shell, read & write files, set permissions, and pipe commands — enough to live inside a sandbox or container prompt.

Lessons in this path

• The Round Trip — Watch one command travel and return.
• The Filesystem Tree — Everything is a file. Walk the tree.
• Reading & Writing — See where text goes when you read and write.
• Permissions — the gate — Watch the kernel check if you're allowed.
• Names vs Things — inodes & links — A filename is a label, not the file.
