Release 0.11.0 · uutils/coreutils

Rust Coreutils 0.11.0 Release:

We are happy to announce the release of Rust Coreutils 0.11.0 - a release focused on error messages, performance and GNU compatibility.
The big change is a new diagnostic engine built on ariadne. When a chmod mode, a cut list, a sort key or a tr set fails to parse, we now echo the arguments back with a caret under the character at fault, like a compiler does. See our blog post for more information: https://uutils.org/blog/2026-08-error-diagnostics/

Example with cut:

or test:

PGO release builds are enabled for Linux, macOS and Windows (up to 31% faster), and a lot of per-utility optimization work landed on top of that. We also now treat a utility being significantly slower than GNU as a bug.

We continued to improve the GNU compatibility and we are now at 653 passing, 22 failing, 0 errors.

GNU Test Suite Compatibility:

Result	0.10.0	0.11.0	Change 0.10.0 to 0.11.0	% Total 0.10.0	% Total 0.11.0	% Change 0.10.0 to 0.11.0
Pass	645	653	+8	94.44%	95.33%	+0.89%
Skip	9	10	+1	1.32%	1.46%	+0.14%
Fail	28	22	-6	4.10%	3.21%	-0.89%
Error	1	0	-1	0.15%	0%	-0.15%
Total	683	685	+2 (new tests)

Note: 653 passing and 23 failing are both records for us, and this is the first release with no erroring test. Note that the suite grew by 2 tests this cycle (local backport). We also list the tests excluded from the pass/fail percentages now.

Highlights:

Modern Error Diagnostics (new)
- A new diagnostic engine based on ariadne. When stderr is a terminal, a parse error is printed as a report: the arguments are echoed back as a source line, a caret marks the culprit and a help line explains the syntax. See the blog post for before/after examples
- Carets landed in chmod, mkdir, mkfifo, mknod, install, tr, expr, sort, numfmt, cut, env, head, tail, truncate, split, shred, stdbuf, od, seq, dd, stat, join, csplit, ls, df and du
- A caret can point inside a quoted argument and at a single character. The reports are localized (format, checksum and advice strings) and still print the usual Try '... --help' hint. A label is only added when it says something useful
- UUTILS_DIAG controls the behavior, and the caret rendering can be compiled out for size-constrained builds
- Diagnostics are written in a single stderr call, so concurrent writers cannot interleave them
Performance
- PGO (profile-guided optimization) release builds: up to 31% faster - now enabled for the published Linux, macOS and Windows artifacts too.
- cp: opens the file only once (+32.93%) and reuses the already-open destination fd when a reflink clone falls back
- join: 1.37x faster on paired input, 2.5x faster than GNU, by skipping the locale comparison when it cannot change the result
- od --skip-bytes uses splice(2) on non-seekable input; tac uses fast_copy; dd no longer faults in the whole copy buffer before reading and page-aligns its read buffer
- Fewer allocations and syscalls in ptx (+4% via fxhash, plus fewer per-word allocations), nl (hoisted per-line prefix), tail (no double allocation per reverse chunk, no stat), expand/unexpand (no stat/is_dir), numfmt and sort
- New benchmarks for ptx, basenc and the numfmt stdin path
- A utility being significantly slower than GNU is now considered a bug - please report it as one
GNU Compatibility
- 653 passing GNU tests (+8), 23 failures (-6) and no erroring test
- New GNU-matching options: uname -A/--all-labeled, cut -F and --whitespace-delimited, pr --columns/--join-lines/-f alias and an optional argument for -n
- Behavior fixes in pr (page length of exactly 10, columns that do not divide evenly, -e at the end of a cluster), numfmt (leading +, scientific notation), uniq/truncate/paste (a repeated option overrides the earlier one), join -o accumulating fields, id group ordering, unexpand/expand tab-list separators, mkdir EEXIST, more -f/-l, fold widths, sort -t=, stat nanosecond timestamps and Block size, od 16 significant digits, date trailing timezones
- A new gnu/usage_vs_refs.sh check verifies that every option we document also appears in GNU's texi docs
- More error messages carry the real OS text instead of a stripped or made up one (rm, env, od, chroot, stdbuf, tee, cut, date, tsort, pathchk, sort)
Security Hardening
- mv/cp: xattr TOCTOU fixed by moving to file-descriptor-based operations
- rm: no longer follows a symlink swapped in at the -r operand
- chmod: uses fchmodat for recursive mode changes and no longer follows in-tree symlinks with -R --reference
- cp: does not chmod through the destination symlink; mv does not put a symlink in its target's hardlink group
- stdbuf: fixed a temporary-directory leak
Robustness: Anti-Panic & Anti-Hang
- Hangs fixed: split endless loop, yes deadlock, sort Lines fuse when a chunk boundary lands exactly at EOF
- Panics and aborts fixed in stat and csplit on /dev/full, ls with an invalid QUOTING_STYLE on unwritable stderr, od on large ASCII dump widths, printf on large numeric and %s/%c field widths, nl with -w i32::MAX (rejection plus a 32-bit OOM fix), pr and csplit integer overflow, dd u64 wraparound, touch leap-second year overflow, tail -c +N past the seek limit, tac SIGBUS on a truncated mmap, who -q stdout write errors
- uucore::parse_size no longer overflows on a large % size
Cross-platform Reach
- Windows: kill and uptime implementations, and test -ef, -t, -h/-L, -r, -w, -x
- WASI: touch timestamps, cp symlinks, expr, cleaned-up core platform abstractions and cat integration coverage
- df got a fallback statfs path using the mount table; uptime dropped its /proc dependency on more targets; stty and chgrp are now gated by target support; better iOS and Fuchsia handling
Dependency Diet
- Dropped byteorder, same-file, filetime, winapi-util, file_diff, mockstream, binary-heap-plus, compare, arrayref, exacl and dns-lookup in favor of std, rustix and windows-sys
Internationalization
- Symbolic mode parsing errors, the chmod --verbose messages and the new diagnostic strings are now translatable
- ls sorts names using locale-aware collation, comm compares lines with the locale collation, nl supports multibyte one-character section delimiters and cut handles multibyte fields, bytes and delimiters correctly
- uucore rebuilds its embedded locales when the consumer's dependencies change
