    Hi,

    I was recently asked in an interview the number of processes that are created when I enter in a command that contains a pipe.

    For eg. If I enter the command: $who | tee /dev/tty | wc -l

    Could anyone tell me how many(which) processes are created and in what order are they created?

    Thanks.
