Erro Crontab “Sem crontab para root”

quando eu escrevo crontab -ecomando no terminal,

Recebo esta mensagem de erro:

no crontab for root - using an empty one 888

Não sei o que significa '888'?

Arquivo de configuração do 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

Por favor me ajude.

Obrigado.

Seu crontabeditor foi mudado para ed. Para sair ed, pressione Qe posteriormente Enter. Isso encerrará o ededitor.

Se você gostaria de mudar seu crontabeditor novamente para nanousar:

sudo select-editor

Isso também pode ser útil:

EDITOR=nano crontab -e

Esse é o número de caracteres no arquivo padrão. O Ubuntu cria um arquivo crontab 'vazio' com muitos comentários mostrando como usá-lo.

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
