前段时间我设置了一个 cronjob,运行良好。它每天 20:00 执行一次 mysqldump。这是 syslog 输出:
Nov 03 20:00:01 server CRON[124238]: (user) CMD (mysqldump --defaults-extra-file="/home/user/.my.cnf" --all-databases -u user > /home/user/Dropbox/mysql-backup.sql
问题是,如果我这样做,crontab -l
我会得到no crontab for user
- sudo crontab -l
>no crontab for root
我查看了:
/etc/crontab
/etc/cron.hourly/
/etc/cron.d/
/etc/cron.daily/
/etc/cron.hourly/
/etc/cron.monthly/
/etc/cron.weekly/
我找不到这个任务。
这/etc/crontab/
是默认的:
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# 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

52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

有什么方法可以找到我设置 cronjob 的地方吗?
