Por que "crontab -l" não mostra todas as tarefas?

  • 772

Adicionei o seguinte ao /etc/crontabmeu sistema Linux:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed
0 0 */1 * * root chmod +x /root/source/auto-renew.sh && /root/source/auto-renew.sh >> /root/source/auto-renew-cron.log 2>&1

No entanto, quando executo agora crontab -l, ele não mostra esta tarefa do crontab:

[root@iZm5e2jhfbrshckqh6qdbuZ cron.d]# crontab -l
45 6 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null

Por que não está crontab -lmostrando a /etc/crontabtarefa?

Este é o registro:

[root@iZm5e2jhfbrshckqh6qdbuZ cron.d]# journalctl -u crond

    crontab -lmostra o arquivo crontab por usuário (em algum lugar como /var/spool/cronou algo assim). Ele pode ser usado por qualquer usuário, e root não é uma exceção aqui.

    Os arquivos /etcsão crontabs de todo o sistema, não vinculados a um usuário específico, e a crontabferramenta não os edita.

    Talvez você queira usar arquivos em /etc/cron.d, ou /etc/cron.dailyetc. para melhor compartimentação.

    Há mais discussão sobre isso em, por exemplo, System Crontab ou Root Crontab
