`shuf(1)` on Solnix vs Linux and the BSDs

shuf is not in the Solnix base system. You add GNU coreutils shuf with pkgs.solnix.coreutils. Its page matches the Linux GNU shuf page: same synopsis, same options. The bundle has no BSD shuf page, so no BSD comparison can be made from it.

The manual pages

Solnix: shuf(1) from pkgs.solnix.coreutils
Linux: shuf(1) coreutils-full-9.11

What Solnix runs

Not installed by default: add pkgs.solnix.coreutils. The Solnix page is the GNU coreutils shuf page (footer: GNU coreutils 9.7, April 2025). No illumos variant of shuf is listed in the bundle.

Differences

Compared with	Topic	What differs
Linux	same program	Solnix and Linux both document GNU coreutils shuf. The SYNOPSIS and the option list (`-e`, `-i`, `-n`, `-o`, `-r`, `-z`, `--random-source`, `--help`, `--version`) are identical in the two pages. Source: Solnix shuf(1) SYNOPSIS and DESCRIPTION; Linux shuf(1) SYNOPSIS and DESCRIPTION
Linux	coreutils version	The Solnix page footer says GNU coreutils 9.7 (April 2025). The Linux counterpart in the bundle is labelled coreutils-full-9.11. The two option lists are identical. Run shuf `--version` to see which release you have. Source: Solnix shuf(1) footer line; bundle header 'COUNTERPART linux: shuf(1) [Linux (coreutils-full-9.11)]'
all four	availability on Solnix	A default Solnix system has no shuf on PATH. Install pkgs.solnix.coreutils to get it. A script that calls shuf will fail with command not found on a base install. Source: Bundle header 'On a default Solnix system the command on PATH is: none: install pkgs.solnix.coreutils'
FreeBSD, OpenBSD, NetBSD	BSD counterparts not in bundle	The bundle includes no FreeBSD, OpenBSD or NetBSD shuf page. The manual texts given here do not say whether those systems ship shuf or what options it has. Check each system's own manual before relying on it. Source: Bundle header lists only 'COUNTERPART linux'
all four	not a POSIX utility	shuf is not a POSIX.1-2024 utility, and the page gives no STANDARDS section. Its options are documented only as GNU coreutils behaviour. Source: Bundle header 'POSIX.1-2024 utility: no'; Solnix shuf(1) has no STANDARDS section

Standards

POSIX: shuf is not a POSIX.1-2024 utility.

Writing portable scripts

Test for shuf with command -v shuf before using it. It is not in the Solnix base system and is not POSIX, so provide a fallback or require pkgs.solnix.coreutils.
Stick to the options both pages document (-e, -i, -n, -o, -r, -z, --random-source) and do not assume anything else exists in other shuf implementations.

Every difference here is taken from the manual pages linked above: Solnix's published page, Linux (man-pages and the GNU and util-linux manuals), FreeBSD, OpenBSD and NetBSD. Each row names its source. Where a manual is silent, this page is too. Compiled 2026-10-26. Found a mistake? Mail hackers@lists.solnix.io.
