![Cron은 내가 작성한 Cron 작업을 실행하지 않습니다. [중복]](https://linux55.com/image/219110/Cron%EC%9D%80%20%EB%82%B4%EA%B0%80%20%EC%9E%91%EC%84%B1%ED%95%9C%20Cron%20%EC%9E%91%EC%97%85%EC%9D%84%20%EC%8B%A4%ED%96%89%ED%95%98%EC%A7%80%20%EC%95%8A%EC%8A%B5%EB%8B%88%EB%8B%A4.%20%5B%EC%A4%91%EB%B3%B5%5D.png)
Cron Job을 작성했지만 실행되지 않았습니다. 왜 실행되지 않는지 아시나요?
내가 실행하고 싶은 Cron 작업은 다음과 같습니다.
#
#
# (day of month) (day of week)
# min hou dom (day of month) mon dow (day of week) command
* * * * * /usr/bin/touch /DATA/z_test_$(date '+%Y-%m-%d_T%H-%M').txt >/dev/null 2>&1
매분마다 실행되어야 합니다.
빈 파일을 만들어 /DATA/ 디렉터리에 저장하고 싶습니다.
이것은 내 파일 시스템의 루트입니다.

'srv_data'나는 /DATA/ 디렉터리에 파일을 생성하고 저장할 수 있는 권한이 있는 사용자로 이 Cron 작업을 실행하고 있습니다 .
나는 또한 이 명령을 사용하고 사용자로부터 실행해 보았고 'srv_data'효과가 있었습니다. 내가 예상하는 위치에 파일이 생성됩니다.

하지만 이 cron 파일 로그를 읽을 수 없습니다. 나는 그것을 전혀 이해하지 못합니다. 이 파일의 5열에 있는 및 는 무엇입니까 CMD?CMDOUT
무슨 /bin/sh: -c:뜻인가요? ?
