chkdiskspace - データ領域のディスク使用量と制限を表示する
[書式]
chkdiskspace [オプション]
[説明]
chkdiskspaceコマンドは、グループで使用する各VOLUMEのディスク使用量と制限を表示できる。
各ボリュームのディスク容量とディスク使用量を確認できるため、データを格納するVOLUMEを判断する為に使用できる。
課題責任者とシステム管理者がこのコマンドを利用できる。それ以外の利用者は利用できない。
[オプション]
-c
検索結果をCSV形式で標準出力する。リダイレクション機能を使用することでファイルに保存することもできる。
-g GROUP_NAME
グループ名を指定する。スペースに続けての複数指定、アスタリスクを使用した前方／中間／後方一致指定はできない。
単一、完全一致指定のみ可能である。
--help
コマンドのヘルプ内容を表示する。
