Hi. I'm trying to figure out the best way to detect when my program is being piped data.
So far I've used in linux often "[[ -p /dev/stdin ]]". During an interactive session, /dev/stdin will be a character device, not a pipe, and if stdin is closed ( command 0<&- ) then it's nothing. But in cygwin, /dev/stdin is ALWAYS a pipe. So, I could use "[[ -t 0 ]]" to check if stdin is a tty, but that would not cover when running my script in a background job or service with a closed stdin. So, a) what is the correct way to detect if stdin is being piped data and b) is this a bug or design limitation ? Thank you. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
