はじめに
Dropboxが無料では3台のPCしか接続できなくなったので、オンラインストレージの活用方法を検討した結果、rcloneという筆者好みのコマンドラインインターフェース（CLI)のコマンドを見つけた。
ここでは、rcloneのインストール、GoogleDriveとDropboxへの接続設定、簡単な使い方について記述する。
インストール
インストールは、Debianのパッケージになっているので、以下のように簡単できる。
sudo apt install rclone
Google Driveの設定
Google Driveの設定ファイルを作成するが、以下のページを参考にした。多謝 m(__)m

少々長いが、以上でGoogle Driveの設定は終了。
Dropboxの設定
続いて、Dropboxの設定は、以下のサイトを参考に行った。多謝 m(__)m
$ rclone config 2020/07/25 17:27:55 NOTICE: Config file "xxxxxxx/.config/rclone/rclone.conf" not found - using defaults No remotes found - make a new one n) New remote s) Set configuration password q) Quit config n/s/q> n name> dropbox <== 名前は dropbox としました。 Type of storage to configure.

For more help and alternate methods see: https://rclone.org/remote_setup/ Execute the following on the machine with the web browser (same rclone version recommended): rclone authorize "dropbox" Then paste the result below: result> hoge@pad:~$ rclone authorize "dropbox" If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth Log in and authorize rclone for access Waiting for code... Got code Paste the following into your remote machine ---> {"access_token":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","token_type":"bearer","expiry":"0001-01-01T00:00:00Z"} <---End pastehoge
ちなみに、Dropboxの場合、アプリを介しての接続が3台までで、ブラウザ経由またはrcloneで『Dropbox』を開く場合は、３台までという制限はない。
簡単な使い方
ファイルの一覧の表示
$ rclone ls gdrive: $ rclone ls dropbox:
ファイルのコピー
$ rclone copy rclone.txt gdrive: $ rclone copy gdrive:text.txt .
ファイルの同期
rclone sync で同期できるが、リモート側のファイルをいきなり削除する可能性があるので、--dry-run オプションを付けてテスト実行した後、実行した方が良い。
$ rclone sync source:path dest:path --dry-run # テスト実行 $ rclone sync source:path dest:path
おわりに
rcloneは、ファイルの更新等に応じて自動的に同期やコピーを行ってくれない点は、い面倒であるが、rcloneひとつで複数のネットワークデータサービスを活用できる点は、とても便利だ。
特にDropboxは無料で最大3台までの制限があるため、3台より多いPC間のデータ共有には、かなり威力を発揮すると思われる。
また、何かわかったら追記する。
