Galat Crontab “Tidak ada crontab untuk root”

ketika saya menulis crontab -eperintah di terminal,

Saya mendapatkan pesan kesalahan ini:

no crontab for root - using an empty one 888

Saya tidak tahu apa arti '888'?

File konfigurasi crontab / etc / crontab:

# /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 )
9 5 28 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#

Tolong bantu aku.

Terima kasih.

crontabEditor Anda telah dialihkan ke ed. Untuk keluar ed, tekanQ dan selanjutnya Enter. Ini akan keluar dari ededitor.

Jika Anda ingin mengubah crontabkembali editor Anda untuk nanodigunakan:

sudo select-editor

Ini juga mungkin membantu:

EDITOR=nano crontab -e

Itu jumlah karakter dalam file default. Ubuntu membuat file crontab 'kosong' dengan banyak komentar yang menunjukkan cara menggunakannya.

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
