The Rift gate requires all four fragments

You stand at the edge of the Rift — a swirling chasm where data streams collide. The rules here are different: commands don't just run, they flow into each other. Master the pipe and you master the dungeon.

🎯 Quest Objectives

  • Pipe command output to another command using |
  • Chain commands with && (run next only if previous succeeds) and || (run next only if previous fails)
  • Redirect stdout to a file with > and >>
  • Redirect stderr with 2> and combined with 2>&1
  • Use tee to split output to file and terminal
  • Navigate arena → pit → spire → mezzanine → .elevator → .satellite
  • Defeat the pit boss and the satellite boss
  • Complete the Bashcrawl dungeon

🗺️ Quest Prerequisites

All of these should be in your inventory before entering the Rift:

  • Stone key fragment (from Chamber)
  • Ancient tome (from Chapel)
  • Vault key fragment (from Vault)
  • Portal crystal (from Scrap)

⚡ Command Cheatsheet

Syntax What It Does
cmd1 \| cmd2 Pipe stdout of cmd1 to stdin of cmd2
cmd1 && cmd2 Run cmd2 only if cmd1 succeeds (exit 0)
cmd1 \|\| cmd2 Run cmd2 only if cmd1 fails (non-zero exit)
cmd1 ; cmd2 Run cmd2 always, regardless of cmd1 exit
cmd > file Redirect stdout to file (overwrite)
cmd >> file Redirect stdout to file (append)
cmd 2> err.log Redirect stderr to file
cmd 2>&1 Redirect stderr to same destination as stdout
cmd > out.log 2>&1 Redirect both stdout and stderr to file
cmd \| tee file Print to terminal AND write to file

🗺️ Walkthrough

Step 1 — Assemble the Rift Key

# The Rift gate requires all four fragments
ls -F
# arena/  rift_gate  key_assembler*

inventory
# stone key fragment, tome fragment, vault key fragment, portal crystal ✓
# (inventory is a Bashcrawl game command, not a standard shell command — it lists what you carry)

./key_assembler
# All fragments combined → Rift Key obtained.

Step 2 — Arena — Master the pipe

cd arena
ls -F
# combatants  scoreboard  arena_boss*

cat combatants | sort | uniq
# Unique combatant list, sorted alphabetically

cat combatants | grep "elite" | wc -l
# Count of elite combatants

# Engage the arena boss
./arena_boss

The arena boss asks pipe-based puzzles. Answer by constructing the right pipeline.

Step 3 — Pit — Command chaining

cd ../pit
cat instructions
# "Raise the drawbridge ONLY if the watchtower lights up. Fail gracefully."

./watchtower && ./raise_drawbridge
# If watchtower succeeds: drawbridge raised.
# If watchtower fails: drawbridge untouched.

./watchtower || echo "Watchtower failed — lighting torches instead."

./pit_boss

Step 4 — Spire — Redirection

cd ../spire
cat spire_challenge
# "Capture all output from the oracle — both wisdom and errors — into oracle.log"

./oracle > oracle.log 2>&1
cat oracle.log

# Run again and APPEND to the same log instead of overwriting:
echo '--- additional run ---' >> oracle.log
./oracle >> oracle.log 2>&1

# Capture ONLY the errors (stderr) and leave wisdom on screen:
./oracle 2> errors_only.log

# Also capture everything with tee so you still see it:
./oracle 2>&1 | tee oracle.log

Step 5 — Mezzanine — Advanced chaining

cd ../mezzanine     # mezzanine is a sibling of spire under the Rift root (like arena → pit → spire)
# Combine all techniques:
ls -la | sort -k5 -rn | head -10 > biggest_files.txt
# -k5 sorts by column 5 (file size); -rn is reverse numeric (largest first)
cat biggest_files.txt

Step 6 — Hidden areas: .elevator and .satellite

ls -a
# .  ..  .elevator/  .satellite/

cd .elevator
ls -F
# control_panel  floor_select*

./floor_select
cd ../.satellite
ls -F
# transmitter*  signal_logs  satellite_boss*

cat signal_logs | grep "ERROR" | tee error_report.txt
cat error_report.txt

./satellite_boss

# Confirm the dungeon registers as finished:
map
# All chambers should now read as complete.

The satellite boss is the final encounter. It uses all skills: pipe a command through grep, redirect errors, chain with &&. Complete it to finish the dungeon.

💡 Common Pitfalls

Problem Cause Fix
| not working Confused table escaping with shell syntax In Markdown tables you write \\| to display a literal \|, but in the shell you always type a plain \| — never type \\| as a pipeline
2>&1 must come AFTER > Order matters Always: > file 2>&1 not 2>&1 > file
&& chain stops early A command failed Add \|\| fallback or check exit codes
Hidden dirs not found Forgot ls -a Always use ls -a in unfamiliar directories

✅ Validation

  • You can build a 3-command pipeline from memory
  • You know the difference between > and >>
  • You understand why 2>&1 must follow >
  • Both pit boss and satellite boss are defeated
  • map shows all chambers as complete

➡️ Next Steps

  • The dungeon is complete! Celebrate your mastery.
  • Capstone → Agent Mode for advanced automation
  • Extend the dungeon → Bash Run
  • Back to hub → Bashcrawl Hub
