보시다시피출입 불가을 위한 ReconectadorVPN.sh. 다른 사용자에게는 crontab이 없거나 다음과 같습니다.
luis@Fostrot:~$ crontab -l
no crontab for luis

답변1
크론 매뉴얼 페이지에서:
Cron searches /var/spool/cron for crontab files which are named after accounts in crontabs found are loaded into memory. Cron also searches for /etc/crontab and the files in the directory, which are in a differ- ent format (see crontab(5) ).
사용자 crontab을 살펴보았지만 없는 것 같습니다 /etc/crontab. 일반적으로 여러 cron 디렉토리에서 항목을 실행하기 위한 항목이 포함되어 있습니다.
답변2
요즘 crontab을 찾아야 할 곳이 몇 군데 있습니다:
물론 개별 사용자 crontab은 일반적으로 사용자 루트 및 기타 사용자의 crontab을 포함하는 /var/spool/cron/에 있습니다.
/etc/crontab에 루트 전용 crontab이 있습니다. 내가 아는 한 여기에는 각 작업의 파일이 있는 실행 섹션 디렉터리에 대한 참조가 포함되어 있습니다. 일반적으로 /etc/cron.daily /etc/cron.hourly /etc/cron.monthly에 있습니다.
요즘 crontab을 찾을 수 있는 또 다른 영역은 /etc/cron.d/ 디렉토리 아래인데, 내가 알 수 있듯이 요즘 이 디렉토리가 더 인기를 얻고 있는 것 같습니다. 이러한 영역의 파일은 일반적으로 루트 수준 실행에 사용됩니다.
