When we want to check whether current terminal is attached to stdin, stdout and stderr streams or not, we can use the below codes. I tried with piping, and redirection so both works well.
As seen in below 6 usages, stdin is not listed in output of commands except first one. Because stdin is used by piping or redirection.
