Safely Inspect Contents On A Specified Git Branch.sh

# Try to show the contents of docs/ from the master branch.
# - git show works for files, but may fail for directories.
# - Suppress errors and limit output to 20 lines.
# - If that fails, fall back to listing files under docs/ instead.
# - Always show only the first 20 results to keep output predictable.
git show master:docs/ 2>/dev/null | head -20 \
  || git ls-tree -r master --name-only | grep '^docs/' | head -20
