このコマンドが出力に使用されるのをどのように防ぐことができますかservice <name> status？less
一部のシステム管理タスクを自動化するスクリプトがあり、サーバーをUbuntu 16.04にアップグレードした後にlessshow出力、特にsupervisorサービスなどを使用したため、サービスの状態を確認する操作がブロックされて問題が発生しました。
実行する複数のデーモンを構成し、実行すると次のような結果がsudo service supervisor status得られます。

手動で下にスクロールするか、Q終了を押すまで返されません。この機能を無効にする方法は？
ベストアンサー1
service statusUbuntuはコマンドが実際に呼び出されるシステムシステムでsystemctl statusあり、必要な操作を正確に実行するオプションがsystemctlあります。したがって、スクリプトで直接コマンドを使用することをお勧め--no-pagerします。systemctl
sudo systemctl --no-pager status supervisor
環境変数SYSTEMD_PAGER
@jwodderが指摘したように、別の方法はSYSTEMD_PAGER環境変数を設定することです。これsystemctlのもう一つの利点はservice。
export SYSTEMD_PAGER=
sudo service supervisor status
同じ結果が得られます。
