sudo kill -9 $CURRENT_PID

sudo kill -9 $CURRENT_PID 명령어는 $CURRENT_PID 환경 변수에 저장된 프로세스 ID (PID)를 가진 프로세스를 강제로 종료하는 명령입니다.

명령어 구성 요소

  • sudo: 이 접두어는 'superuser do'의 약어로, 다른 사용자의 보안 권한(대개는 슈퍼유저, 즉 root)으로 명령을 실행합니다. 이를 통해 시스템에 대한 관리 명령을 실행할 수 있습니다.

  • kill: 이 명령어는 특정 프로세스에 시그널을 보내는 데 사용됩니다. 이 시그널은 프로세스에 종료하라는 명령, 상태를 변경하라는 명령 등을 전달할 수 있습니다.

  • 9 (or SIGKILL): **9**는 SIGKILL 시그널을 나타냅니다. **SIGKILL**은 프로세스를 즉시 종료시키는 강력한 시그널로, 프로세스가 이 시그널을 무시하거나 차단할 수 없습니다. 일반적으로 시스템이나 사용자가 어떤 프로세스를 강제로 종료시켜야 할 때 사용됩니다.

  • $CURRENT_PID: 이 부분은 환경 변수 **CURRENT_PID**의 값을 나타냅니다. 이 변수는 특정 프로세스의 PID를 저장해야 합니다.
