tty problem with Cron Job

[Seah Hee Chuan]

Hi, is it true that when I run a shell script command with cron job, cron job will not know what terminal it is on?
Can I set the terminal for my application, to a specific terminal eg /dev/pts/2 in a cron job.
Or should I do that in my shell script.But how?
Thank You

Yes, this is true.

You can set the variable TERM in the script.

You can even if you wish pull your stty statements from /etc/profile or .profile and put them in the script.

Usually if the job needs a TERM variable set, thats enough.

Another thing to check in cron jobs: PATH

cron provides its jobs no environment whatsoever, they need to do that for themselves.

I have just tried writing small script to detect what tty crontab used.

#!/usr/sbin/sh
tty>/tmp/ttyid.log
and setting crontab.
and check
#cat /tmp/ttyid.log
not a tty.

It mean crontab does not use shell as tty.
