`bun <path>.lockb` listed the directory of the lockfile, loaded the default `.env` files and built `PackageManagerOptions` before it printed the yarn.lock. The yarn printer reads only the lockfile, so nothing used the result. `--no-env-file` and bunfig `env = false` had no effect, and a `.env` that could not be opened ended the command with `An internal error occurred (ELOOP)`. `printer::Yarn::print` now takes `&Lockfile`, so no caller can build options or load `.env` files for it. `Printer::print_with_lockfile` and `PrinterFormat` are removed. `bun <path>.lockb --hash` prints the hash that the lockfile stores. It no longer calls `PackageManager::init`, so it needs no package.json, reads no `.env` file and prints no loaded-files line to stderr. It no longer parses `bun pm` flags.
The lockfile printer was the only caller that passed no `CommandLineArguments`. `Options::load` now takes them by value, as both remaining callers pass them.
The command runs as "nobody" through runuser, because root can list any directory. The text lockfile fixture is shared with the `.env` test.

Make the .env fixture work without Windows symlink privileges.
writeUnopenableEnv awaits fs/promises.symlink(".env", join(dir, ".env")). On supported unprivileged Windows hosts without Developer Mode or symbolic-link privilege, fixture creation can fail before Bun runs and before either lockfile assertion executes. Use a Windows-compatible fixture, or skip these two tests when self-referential symlink creation is unavailable.

🟡 (optional) Users who run bun <path>.lockb --hash --silent (CI scripts, git textconv wrappers) now get error: failed to parse lockfile: ... on stderr for a corrupt or truncated lockfile; the base printed nothing. print_hash at src/runtime/cli/package_manager_command.rs:119 passes a hard-coded LogLevel::Default to handle_load_lockfile_errors_for, so the --silent, --verbose and --help flags that the base parsed via CommandLineArguments::parse(Subcommand::Pm) are silently ignored in every argument position. Fix: derive the log level for the --hash form from argv (at minimum honor --silent and --verbose), or reject unknown bun pm flags instead of accepting and ignoring them; test/cli/install/bun-lockb.test.ts:156 currently locks the regression in.
Why this was flagged
A user runs bun bun.lockb --hash --silent on a truncated or corrupt lockfile, reaching bun_lockb at src/runtime/cli/mod.rs:1930 and then print_hash. On the base, print_hash called CommandLineArguments::parse(Subcommand::Pm) and PackageManager::init, and passed pm.options.log_level (Silent) to handle_load_lockfile_errors_for, so not_silent at src/runtime/cli/package_manager_command.rs:80 was false and nothing was printed. The new code at src/runtime/cli/package_manager_command.rs:119 passes LogLevel::Default unconditionally, so Output::err_generic at :96 fires and stderr gains error: failed to parse lockfile: Lockfile is missing data. The same drop applies to --verbose (no Loaded N ... lines, Buffers.rs:409-413) and --help. The author lists this as an accepted downside and the new test at test/cli/install/bun-lockb.test.ts:156 asserts the noisy output, but no maintainer agreed to drop flag handling for this entry point; the fix should read --silent/--verbose from argv the same way the --hash scan at mod.rs:1930 already does.
Verification: Trigger: a user runs bun <path>.lockb --hash --silent on a corrupt/truncated lockfile. Head src/runtime/cli/package_manager_command.rs:117-119 passes hard-coded LogLevel::Default, so not_silent at line 80 is always true and line 96-99 prints failed to parse lockfile: .... On the base, print_hash passed pm.options.log_level, which --silent set to Silent. Exit code stays 1.

🟡 (optional) On a root Linux CI runner the new runuser test fails instead of skipping when nobody cannot traverse the temp directory, turning the install suite red. The runner sets TMPDIR to a mkdtempSync directory (scripts/runner.node.ts:1966-1972), which is created mode 0700; test/cli/install/bun-lockb.test.ts:199 chmods only the test's own tempDir to 0755, so cd '${project}' run as nobody at :204 fails with exit 1 or 126 and the expected printedTextBunLock object does not match. Fix: before spawning, probe that nobody can reach both the temp dir and bunExe() (or chmod the TMPDIR parent) and skip with a reason when it cannot, so the gate at :190-194 reflects the real precondition.
Why this was flagged
When CI runs the suite as root on Linux with runuser and a nobody user present, canRunAsNobody at test/cli/install/bun-lockb.test.ts:190-194 is true and the test runs. tempDir (test/harness.ts) creates the directory under os.tmpdir(), which the runner has pointed at a fresh mkdtempSync directory (scripts/runner.node.ts:1966, TMPDIR at :1972); mkdtempSync creates it 0700 owned by root. The chmod at :199 fixes only the leaf tempDir, not its 0700 parent, so /bin/sh -c cd ... as nobody fails before bun starts and the Promise.all at :209 yields a non-zero exitCode and empty stdout, failing the toEqual at :210. The dismissal relies on test/cli/run/env.test.ts:1306 using the same pattern, but that test may itself be skipped on non-root runners, so it does not prove the precondition holds; the gate should probe traversability rather than assume it.
Verification: Triggers only when scripts/runner.node.ts runs as root on Linux with runuser and nobody. TMPDIR is a 0700 mkdtempSync dir (runner.node.ts:1966, :1972); bun-lockb.test.ts:199-201 chmods only the leaf, so cd as nobody (:204) gets EACCES and :210 fails instead of skipping; the gate at :190-194 never checks traversal. env.test.ts:1306 already fails the same way on the base branch.

🟣 pre-existing, not blocking: Users who run bun <long path>.lockb --hash with an argv path longer than MAX_PATH_BYTES get a Rust panic (slice index out of range) instead of an error; the base has the same panic but this PR rewrote the surrounding block without fixing it. The --hash arm at src/runtime/cli/mod.rs:1933 copies entry into a pooled path buffer with path_buf[..entry.len()] and never truncates or checks the length, while Printer::print at src/install/lockfile.rs:1646 clamps the same input to MAX_PATH_BYTES. Fix: in the --hash arm, reject or clamp entry to MAX_PATH_BYTES-1 before the copy so both sibling arms of bun_lockb handle oversized argv the same way.
A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
A user passes a lockfile path of MAX_PATH_BYTES bytes or more on the command line, e.g. via a deep monorepo path or a shell glob, with --hash. Dispatch reaches bun_lockb at src/runtime/cli/mod.rs:1921 and the --hash arm; path_buf[..entry.len()].copy_from_slice(entry) at :1933 indexes past the pooled buffer and panics, and path_buf[entry.len()] = 0 at :1934 would do the same. The sibling non-hash arm goes to Printer::print, which truncates at src/install/lockfile.rs:1646, so only the --hash population panics. The base had the identical copy, so this is pre-existing, but the PR moved let entry into shared scope above both arms (:1928) and rewrote the function, and REVIEW.md treats a panic on CLI input as a bug reviewers block on. Remedy: bound-check entry.len() < MAX_PATH_BYTES and return an error naming the path.
Verification: pre-existing. Trigger: bun <path>.lockb --hash where the argv path is >= MAX_PATH_BYTES. entry is the raw positional from argv with no length check. Length > 4096 panics at src/runtime/cli/mod.rs:1933, length == 4096 panics at :1934. The non-hash sibling clamps at src/install/lockfile.rs:1646, so only the --hash arm panics. The base branch has the identical two lines, so merging makes nothing worse.

bun <path>.lockblists the directory of the lockfile, loads its.envfiles and buildsPackageManagerOptionsbefore it prints (Printer::print_with_lockfile,src/install/lockfile.rs:1770).
