How to Start a Session

Tell Claude: "Let's play Bash Quest" or "Continue SLM-bash" Claude will read the game files and pick up where you left off!

Session 1 - 2026-01-08 (with Claude Opus 4.5)

Session Summary

Started as a bash learning session, evolved into building a full game project. Lukas suggested the Socratic method, then expanded scope to include:

  • Spaced repetition & active recall
  • A leveling system
  • Building a deployable web app
  • Eventually giving this to his son

Concepts Covered

  1. The Prompt (username@hostname:~$)

    • ~ = home directory
    • $ = regular user (vs # for root)
    • Visual indicator of privilege level

  2. ls - list directory contents

    • ls -l = long format (detailed info)
    • ls -a = all files (including hidden)
    • ls -la and ls -l -a are equivalent (flags can be combined)

  3. cd - change directory

    • Relative path: cd projects (from current location)
    • Absolute path: cd /home/lukas/work/projects (full path from root)

  4. man - manual pages

    • Already knew this! Use man <command> to learn about any command

  5. mkdir - make directory

    • mkdir -p for nested/parent directories

  6. touch - create empty file / update timestamp

    • Originally for updating timestamps, creating files is a side effect

  7. File viewing

    • cat = concatenate, dumps whole file
    • less = pager, scroll up/down, search with /, quit with q
    • more = older pager, forward-only ("less is more" joke)
    • head -n 20 = first 20 lines
    • tail -n 20 = last 20 lines
    • tail -f = follow file in real-time (for logs)

  8. Redirection

    • > = overwrite file
    • >> = append to file
    • echo "text" > file.txt example

Key Insight

User instinctively reaches for man to learn - this is the right approach. Asks good "why" questions (why is it -n? does more still exist?)

Next Topics to Cover

  • Moving/copying/removing (mv, cp, rm)
  • Pipes (|) - chaining commands
  • grep and finding things
  • Permissions basics
  • Environment variables

Notes

  • Learning style: practical, asks good clarifying questions
  • Prefers understanding why commands are named what they are
