[BlueOnyx:24203] help with crontab

[Meaulnes Legler @ MailList]

hello

I want to install a shell script that runs every day with crontab.

Now I know there is some catch on BlueOnyx for doing that but I didn't jot it down.

[root at vs ~] # crontab -l
returns nothing

[root at vs ~] # crontab -u admin -l
no crontab for admin

[root at vs ~] # crontab -e
edits an empty file

[root at vs ~] # ls -l /etc/crontab
-rw-r--r-- 1 root root 620 2017.03.28-02:57 /etc/crontab


[root at vs ~] # less /etc/crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

04,34 * * * * root run-parts /etc/cron.half-hourly
03,18,33,48 * * * * root run-parts /etc/cron.quarter-hourly
46 0,6,12,18 * * * root run-parts /etc/cron.quarter-daily
/etc/crontab lines 1-18/18 (END)


So there *is* a crontab file but I can't edit it the normal way... can I just edit /etc/crontab and add my line like
5 4 * * * root /root/myScript.sh	# run myScript.sh every day at 04:05
without breaking anything?
Do I have to restart some service?

Thank you and best regards
