定时执行操作命令,每一个用户拥有自己的crontab,那么大家知道怎么看crontab定时任务是否执行呢?接下来大家跟着学习啦小编一起来了解一下的看crontab定时任务是否执行解决方法吧。
看crontab定时任务是否执行方法
1、针对Linux系统的查询方法(含Redhat、SUSE)
看 /var/log/cron这个文件就可以,可以用tail -f /var/log/cron观察
配图为系统aix root用户默认的crontab
2、针对UINX系统查询方法(AIX、HP-UX)
在 /var/spool/cron/tmp文件中,有croutXXX00999的tmp文件,tail 这些文件就可以看到正在执行的任务了。
33. mail任务(Linux UNIX)在 /var/spool/mail/root 文件中,有crontab执行日志的记录,用tail -f
/var/spool/mail/root 即可查看最近的crontab执行情况。
其实最简单的方法还有将crontab的任务执行采用累加的方式输出到一个日志中
注意crontab里定时执行的脚本有足够的权限,如未正常执行,需要常看其日志
