I want to write a c program in which i create multiple child processes and redirect their inputs and outputs to different file descriptors .I goo开发者_开发知识库gled a lot but couldn\'t find relevant
I know how to detect if my Python script\'s stdout is being redirected (>) using sys.stdout.isatty() but is there a way to discover what it\'s being 开发者_运维技巧redirected to?
I\'m redirecting STDOUT and STDERR in a perl script with: open STDOUT, \'>\', $logfile or die \"Can\'t redirect STDOUT: $!\";
i have an dos exe which take argument, perform its functions and display the output in dos. i need to call the dos file from vb passing the argument without showing the dos window, and ge开发者_Pytho

for example, in linux the following command $ firstProgram | secondProgram carries the output of firstProgram as an input to secondProgram
