Crontab错误“没有用于root的crontab”
当我在终端写crontab -e命令时，
我收到此错误消息：
no crontab for root - using an empty one 888
我不知道’888’是什么意思？
crontab / etc / crontab的配置文件：
# /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 # mh dom mon dow user command 58 * * * * root cd / && run-parts --report /etc/cron.hourly 52 0 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 46 0 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 9 5 28 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) #
请帮我。
谢谢。
这是默认文件中的字符数。 Ubuntu创建了一个“空”的crontab文件，其中包含很多显示如何使用它的注释。
crontab -e # Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any').# # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 am every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # mh dom mon dow command "/tmp/crontab.vILdXR/crontab" 22L, 888C
您的crontab编辑器已切换为ed 。 要退出ed ，请按Q ，然后按Enter键 。 这将退出ed编辑器。
如果您想将crontab编辑器更改回nano使用：
sudo select-editor
这也可能有用：
EDITOR=nano crontab -e
