C# 스크립트는 터미널에서 대기하지만 데몬 프로세스로 직접 종료됩니다.

C# 스크립트는 터미널에서 대기하지만 데몬 프로세스로 직접 종료됩니다.
  • 나는 완전한 C# 초보입니다(비록 Java를 알고 있지만).
  • C# 스크립트를 수정했습니다. 시작 시 데몬과 systemctl을 사용하여 실행하고 싶었습니다(원래는NZXT 자동 팬 컨트롤러 스크립트)
  • 이 코드는 4초마다 코드 조각을 실행하고 다음을 사용하여 종료 스크립트를 차단하는 반복 타이머를 생성합니다.Console.ReadLine();
  • msc와 mono를 사용하여 스크립트를 컴파일하고 테스트했습니다. 터미널에서 예상대로 작동합니다(직접 종료되지 않음).
  • 데몬으로 실행하면 Console.ReadLine();대기 시간이 없으며 스크립트가 기본 메소드를 직접 완료하고 종료됩니다.
  • 노트:

    • 저도 Linux moob이므로 데몬에서 뭔가 잘못하고 있는 경우 지적해 주시기 바랍니다. 내 목표는 부팅 시 시스템을 시작하고 중지할 수 있는 백그라운드 스크립트를 만드는 것입니다.

답변1

은 모르겠지만 c#문제는 systemd 서비스로 시작할 때 프로그램의 STDIN이 에 연결되어 있기 때문에 읽기를 시도 /dev/null하면 Console.ReadLine();즉시 결과(0바이트 읽기)를 얻고 반환하기 때문이라고 생각됩니다.

다음과 같은 방법으로 동일한 것을 수동으로 재현할 수 있습니다.

myprog < /dev/null

프로그램이 종료되지 않도록 하려면 이를 수행하는 다른 메커니즘이 필요합니다.
