regularfile visibledir/

The wine cellar wall flickers. A hidden door appears — but only ls -a can see it. Beyond the false stone lies a chapel with five secret areas — the courtyard, the aviary nested within it, the hall, the library, and the graveyard — guarded by a monster who fears knowledge.

About Dotfiles and Hidden Directories

Any file or directory whose name begins with . is hidden from ls by default. Use ls -a to see them.

ls
# regular_file  visible_dir/

ls -a
# .  ..  .CHAPEL/  .hidden_scroll  regular_file  visible_dir/

. is the current directory. .. is the parent. Do not delete either.

🗺️ Walkthrough

Step 1 — Reveal the hidden chapel

From the cellar:

ls -a
# .  ..  armoury/  .CHAPEL/  emerald_amulet  dusty_scroll  recipe*  scrap/  vault/

.CHAPEL/ is invisible with plain ls — only ls -a shows it.

Step 2 — Enter and explore the courtyard

cd .CHAPEL
ls -F
# courtyard/  hall/  library/  graveyard/

cd courtyard
ls -F
# aviary/  birdbath  stone_bench
cat birdbath
# "Birds know the secret. Look to the aviary."

Step 3 — The aviary clue

cd aviary
ls -F
# eagle*  feather  perch/
cat feather
# "The monster fears: man grep"

This tells you to consult man grep — the solution to defeating the monster is hidden in the grep manual.

Step 4 — Study the man page

man grep
# Opens the pager. Search with /pattern
# Press / then type "line number" and press Enter
# Press q to quit

Tip: man grep | grep -- '-n' pipes the manual through grep to find the -n flag quickly. The -- tells grep to treat -n as a search pattern, not a flag.

The relevant knowledge: grep -n prints line numbers. The hall monster demands you specify which line contains the incantation.

Step 5 — Navigate to the hall and fight

cd ../../hall   # from .CHAPEL/courtyard/aviary back up to .CHAPEL, then into hall
ls -F
# inscription  monster*  locked_door

cat inscription
# "Invoke grep with the flag that shows line numbers."

./monster
# The monster demands: "Which grep flag shows line numbers?"
# Type your answer at the prompt and press Enter:
# -n
# The monster falls!

Step 6 — Collect the tome from the library

cd ../library
ls -F
# tome  reading_nook/

cat tome
# The Ancient Tome of Shell Knowledge — tome fragment obtained.
inventory

Note: inventory is a bashcrawl game command (it lists items you've collected), not a standard Unix command.

Step 7 (Optional) — Explore the graveyard

cd ../graveyard
ls -a
# columbarium/  .mausoleum/  royal_tombs/  epitaph

cat epitaph
# "Here lie commands executed without --help."

The mausoleum is another hidden directory. Explore it for bonus lore and a secret item.

💡 Common Pitfalls

Problem Cause Fix
No such directory: .CHAPEL Used ls instead of ls -a Always use ls -a when searching
man opens strange pager Default pager not less Press q to quit; or export PAGER=less
Monster won't accept answer Case sensitivity Try both n and -n
Tome not in inventory Used less instead of cat cat tome adds it to inventory

✅ Validation

  • You can explain why ls -a is needed to see .CHAPEL
  • You know how to search inside a man page
  • The monster is defeated
  • The ancient tome is in your inventory
  • You explored at least four of the five chapel sub-areas
