I usually check if the standard input file descriptor is attached to a
tty device or not.
#!/bin/sh
if [ -t 0 ]; then
echo has a tty
else
echo does not have a tty
fi
exit 0
Or something like:
$ test -t 0 && echo yes tty || echo no tty
Note: This discussion thread is much better suited for help-bash since
it isn't talking about a bug in bash. In the future if you are just
asking questions that would be the better list to send them to.
