Depends on your shell. BASH has an array PIPESTATUS containing the return statuses of the last pipe chain you ran. I'm not sure how ksh does it. If you're in a basic bourne shell, that'd be tricky to do at all.

This function is intended to be used in a fashion similar to the following example: explain_pipe_or_die(pipefd); pipefd The pipefd, exactly as to be passed to the pipe(2) system call.
