PATH変数の正しい形式は何ですか

私はmacOSを持っており、これを行うときに得られる出力は次のとおりです。echo $PATH

PATHシェルが実行可能ファイルを検索するディレクトリのコロンで区切られたリスト。PATH操縦は難しいですが、ツールがあります。私は2000年にLinux Journalで説明されているStephen Collyerのbash_path_funcsを使います。

https://www.linuxjournal.com/article/3645 https://www.linuxjournal.com/article/376​​ 8 https://www.linuxjournal.com/article/3935

addpathこの関数は、最初にそのエントリがパスに存在しない場合にのみパスにエントリを追加します。delpath -nパスに存在しないディレクトリを削除します。uniqpath重複を削除します。

pathfunc.tgzからファイルを受け取ることができます。https://web.archive.org/web/20061210054813/http://www.netspinner.co.uk:80/Downloads/pathfunc.tgz
