I am trying to find how crontab works.
As root
crontab -e
i insert this record
* * * * * ls -l

Where i must see ...the result..of the ls -l?
How often this is being extracted? Continuously?

Stderr, stdout, mail? :)

Usually you'll redirect the output of a command run by
cron to some logfile ...

Well normally you wouldn't, like Tink said, you'll need to direct it somewhere (or you should, by default, receive an email). To direct it:
* * * * * ls -l >/path/to/log/cronlog

Or wherever you'd like.

Then simply view the logfile to see what ls-l is outputing.

Cool

Lets take it from the beggining
i write
crontab -e
i insert this record:
1 * * * * ls -l > home/alaios/temp

quit the crontab

i wait about 10 min
less /home/alaios/temp and the file is null...why?

Because it's only going to run
in the first minute of every hour? :)
