crontab -e터미널에 명령을 쓸 때

이 오류 메시지가 나타납니다.

no crontab for root - using an empty one 888

'888'이 무엇을 의미하는지 모르겠습니다.

crontab / etc / crontab의 구성 파일 :

# /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

# m h 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 )

기본 파일의 문자 수입니다. 우분투는 '빈'crontab 파일을 만들어 사용 방법을 보여주는 많은 주석을 만듭니다.

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 a.m 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)
#
# m h  dom mon dow   command
