What exactly is this "WielsOnLine.txt" file.. is it an executable or just a plain text file? Do you do realize if its a plain text file that isn't executable as in a script of some kind, cron won't do anything with this file!

what it needs to do is the following

it has to write the resalt of "who" in that txt file

greetings linda

Whoops, didn't even notice..
Have you tried placing the full path of who in there? Is crond even running?

solution!

knoppix 3.7 does not activate (start) cron when computers boots it needs to be added in the start up list i am gooing to try find-out how to do this because i myself have never done this before.

i am still learning , i'll be dooing my test in a week

greetings

I think you may be missing a step here, but my examples
are from Redhat, so your mileage may vary:

crontab -l # lists what is actually installed as user's
# crontab to stdoutput
crontab -e # modifies the user's cron tab file and
# automatically replaces it when you exit
crontab -r # removes the current crontab

Other items to check:
* is the cron daemon enabled, as stated earlier by
another poster
* contents of /etc/cron.deny or /etc/cron.allow
policy config files (you only get to use ONE)

And, for jobs to be run by root, Red Hat has a
set of directories and a crontab under /etc so
jobs are run hourly, daily, weekly and monthly.
You DON'T need to edit the /etc/crontab.
As root, you just move the needed script into
one of the directories, for example /etc/cron.daily
for the daily jobs.

If you want to manager their logs in /var/log,
or wherever, you edit the configuration file
/etc/logrotate.conf and ALSO make sure that
the logrotate script appears in the same set
of directories to run at appropriate intervals.
