I thought that was a good idea!
bmike1@c521 ~ $ sudo crontab -u bmike1 -l
no crontab for bmike1
bmike1@c521 ~ $ sudo crontab -u root -l
no crontab for root
bmike1@c521 ~ $
But not in my case. Unless of course there is another user it is run under.
So the mouse wheel in my mind started to creak..... So I inspected the man
for crontab.... which inspired me to cat /etc/cron*....
which lead me down the path to ls /etc/cron.daily/
and in that directory is a file! /etc/cron.daily/apt/
So How to edit the file? Ask PLUG or ask the web? I opted to ask the web.
It told me: edit crontab with crontab -e
So I tried:
bmike1@c521 /etc/cron.daily $ crontab -e /etc/cron.daily/apt
bmike1@c521 /etc/cron.daily $ crontab /etc/cron.daily/apt -e
bmike1@c521 /etc/cron.daily $ sudo crontab /etc/cron.daily/apt -e
and
bmike1@c521 /etc/cron.daily $ sudo crontab -u bmike1 /etc/cron.daily/apt/ -e
all of which responded with:
crontab: usage error: no arguments permitted after this option
usage: crontab [-u user] file
crontab [ -u user ] [ -i ] { -e | -l | -r }
(default operation is replace, per 1003.2)
-e (edit user's crontab)
-l (list user's crontab)
-r (delete user's crontab)
-i (prompt before deleting user's crontab)
bmike1@c521 /etc/cron.daily $
so I looked a little more in the web and so tried:
sudo *crontab -e* bmike1
which gave the same error.
So now I need to ask what I'm doing wrong.
