Linux equivalent of con

What is the Linux equivalent of con?

For example, in DOS, if a program requires a file as input, you can use "con" as the filename, and it will read data from the keyboard.

It all depends on what you want. "/dev/tty" should get you the user terminal, though this is not always the Linux console -- it may be an X-Term. If you're trying for the system console, I believe that "/dev/console" is what you need. You may not have access as a user to the system console, however.

Usually, when passing arguments to a program, you can usually specify - (a dash) as the filename. This has to be implemented by the program, though.

If you're writing a program, use stdin, but that's standard C.

Okay, thanks. I'll have to implement the - filename.
