macOSとCLI環境をアップデート：Rust製coreutils「uutils」を導入してみた

<!-- markdown-mode-on --> 最近､ `dotfiles` を0から作り直しをやってるんだけど､その中で､ CLI ツールを `brew` じゃなくて `mise` からインストールするように変更中に気づいたことをメモしておく｡ 使っているPCは､ macOS なんだけど､ コマンドがBSD系なので微妙にオプションが違ったりして使いにくいから brew を使って coreutils をインストールしてずっと使っていたので､同じように mise でも､ coreutils が使えるか調べたら､ coreutils をRustに置き換えを試みてる uutils の方になるらしい｡ ```bash $ mise search coreutils Tool Description coreutils Cross-platform Rust rewrite of the GNU coreutils. https://github.com/uutils/coreutils ``` <div class="blogcard"><a href="https://github.com/uutils/coreutils" target="_blank"><div class="blogcard-image"><img alt="" loading="lazy" src="https://opengraph.githubassets.com/fd73caf26b7df15ded93feaf12e5719d059048a2b1ae6df34cc8b8bcdc859b1e/uutils/coreutils"></div><div class="blogcard-text"><p class="blogcard-title">uutils/coreutils: Cross-platform Rust rewrite of the GNU coreutils</p><p class="blogcard-description">Cross-platform Rust rewrite of the GNU coreutils.

In this post, I’ll focus on “Modernisation”. There are many areas we could look to modernise in Ubuntu: we could focus on the graphical shell experience, the virtualisation stack, core system utilities, default shell utilities, etc. Over the years, projects like GNU Coreutils have been instrumental in shaping the Unix-like experience that Ubuntu ...</p></div><div class="blogcard-footer"><img alt="" loading="lazy" src="https://www.google.com/s2/favicons?domain=https://discourse.ubuntu.com/t/carefully-but-purposefully-oxidising-ubuntu/56995">discourse.ubuntu.com</div></a></div> 従来の`ls`やHomebrewで入れた`gls`とは異なり、`uutils`は`coreutils <コマンド名>`という形式で利用する。 例えば、`ls`コマンドを使いたい場合は`coreutils ls`と入力すれば使えるようになっている｡ ```bash $ coreutils coreutils 0.1.0 (multi-call binary) Usage: coreutils [function [arguments...]] coreutils --list Options: --list lists all defined functions, one per row Currently defined functions: [, arch, b2sum, b3sum, base32, base64, basename, basenc, cat, chgrp, chmod, chown, chroot, cksum, comm, cp, csplit, cut, date, dd, df, dir, dircolors, dirname, du, echo, env, expand, expr, factor, false, fmt, fold, groups, hashsum, head, hostid, hostname, id, install, join, kill, link, ln, logname, ls, md5sum, mkdir, mkfifo, mknod, mktemp, more, mv, nice, nl, nohup, nproc, numfmt, od, paste, pathchk, pinky, pr, printenv, printf, ptx, pwd, readlink, realpath, rm, rmdir, seq, sha1sum, sha224sum, sha256sum, sha3-224sum, sha3-256sum, sha3- 384sum, sha3-512sum, sha384sum, sha3sum, sha512sum, shake128sum, shake256sum, shred, shuf, sleep, sort, split, stat, stdbuf, stty, sum, sync, tac, tail, tee, test, timeout, touch, tr, true, truncate, tsort, tty, uname, unexpand, uniq, unlink, uptime, users, vdir, wc, who, ```
