親戚のマシンで bash シェル スクリプトを実行する cronjob をインストールしようとしています。彼らはインストールを実行しますが、私はまだリモートでアクセスできません (それが私のスクリプトの目的ですが、ここでは問題ではありません)。kdialog を使用して root パスワードを要求し、それを使用してさまざまなコマンドを sudo したいと考えています。以下の私のコードは、a) ターミナルのルート p/w を明らかにし、b) さまざまな sudo へのパイプに失敗しているため、失敗しています。ヘルプ?

if test -z "$BASH" ; then
printf "$SCRIPT:$LINENO: please run this script with the BASH shell\n">&2
exit 192
