ERROR 详细

修改crontab出现如下错误：

crontab: installing new crontab
“/tmp/crontab.MswKCq”:0: bad minute
errors in crontab file, can’t install.
Do you want to retry the same edit? n
crontab: edits left in /tmp/crontab.MswKCq

根因定位

通过多种方法尝试发现是如下原因导致的；
Googled all round and found that this was the error due to the no space in log folder for cron i.e in /var. Make sure to run df -h /var/ and see if there is enough space there.

通过执行命令df -h /var

总空间为40G，可用空间为0
crontab的log日志高达近39G

删除crontab的log日志后，修改crontab就正常了。

结论

报错太误导人了
