Actually An interviewer has asked this question.

My other question:

What do you mean by "particular terminal"?

This is the question - can you answer it???

The interviewer hasn't really provided you with enough information to answer this question properly. The literal answer would have to be "no" - at least I'm unaware of any method to associate a process started by cron with a terminal. However, that does not mean that the process (script/program/whatever) cannot figure out some way to tie itself to some particular device.

Hi:

'cron' tasks are not associated with terminals! This applies to 'at' jobs too.

Hi (again):

Pete's comments got me thinking creatively. You could (at least) send a message from a 'cron'task to a particular user and/or a particular user at a particular terminal.

# cat ./cronme
#!/usr/bin/sh
write senthil pts/0 < /tmp/cronme.msg
exit

# cat ./cronme.msg
Time to wake-up...
Please call me. - Thanks!

You can see how this might work by using the 'at' or 'cron' facilities to schedule the './cronme' task.

Regards!

If you own a terminal (from another window), you can read/write to that device from a cronjob.
