Hi.

I usually use the very old command tty. This script creates a little shell script that demonstrates tty. It calls the created script directly, and then runs it as an "at" job. The results of at jobs are mailed to you.
Code:
#!/bin/sh

# @(#) s1       Demonstrate tty.

echo " sh version: $BASH_VERSION"

cat >test-tty.sh <<EOF
#!/bin/sh

if tty -s
then
        echo " STDIN is connected to a terminal."
else
        echo " STDIN is NOT connected to a terminal."
fi
EOF

echo
chmod +x test-tty.sh
./test-tty.sh

echo
at -f ./test-tty.sh now

exit 0

Which, when run, produces:
Code:
% ./s1
 sh version: 2.05b.0(1)-release

 STDIN is connected to a terminal.

warning: commands will be executed using /bin/sh
job 14 at 2007-05-14 06:52

and here is the email message:

See man tty for details ... cheers, drl
