all you have to do is set up your crontab, if you want it to run as root, load up a terminal session as root and type in "crontab -e"

all information on setting it up can be found in "man crontab"

if i were you, i'd set up the entry as:

*/2 * * * * /your/command/you/are/trying/to/run/bin/command > /dev/pts/#

replace the /your/command/you/are/trying/to/run/bin/command as the command you're trying to run

then set the /dev/pts/# to the terminal you're trying to send it to, or /dev/tty# if you want it in a Virtual Terminal

crontab is actually just a program to edit your cron settings. The real power is in crond, most distros have this running in the beginning, but you should double check with your settings to make sure it's running at start up.

What crond will do is read your crontab settings and runs the program according to how the crontab was setted up.

So once you've configured it, as root, you should reset your crond with "killall crond" then run "crond", it'll automatically load itself into the background and that should do it.

Thanks tsphan!!!

finally its working buddy!!! But sir, it's displaying the ls -l for /root not for /bin...

i put the script:-

*/2 * * * * /bin/ls -l > /dev/tty2

Waiting for your next respond!!! Thanks.

hurray, it works!
to make it list the bin directory, simply change the command to:

Code:

/bin/ls -l /bin > /dev/tty2

I had made one change, it started working perfectly.

changes were:-

Code:

ls -l /bin > /dev/tty2

I remove the /bin from the starting and putted in the end and it's started working...
