1. The problem statement, all variables and given/known data:
Hi everyone, The script I did below works just fine. My problem is when the script is executed, I receive 2 emails. One is from the script and the other is from our Sun OS system named admiral. The Sun os is ver. 5.10. The mail message I receive is:
"Your "at" job on admiral
"/var/spool/cron/atjobs/1317352641.a"
produced the following output:
stty: : Inappropriate ioctl for device
stty: : Inappropriate ioctl for device
I cannot determine your terminal name. No reply possible.
Warning: You have your terminal set to "mesg -n". No reply possible."

I am trying to figure out what "stty: :In appropriate ioctl for device" means. Can anyone help? Thanks!
