Other times, it is useful to provide the output of a program as the input of another program. The syntax [process A] |[process B] tells your shell to pipe the output of process A to the input of process B. In other words, the output of program A becomes the input of program B. Modify your shell so that it supports pipes between programs. You can assume there will always be spaces around the special character |. You must support an indefinite number of pipes in series, as seen in the example below. To implement this part of the shell, you will need to use the pipe syscall. An explanation for how this syscall works is provided below. Historically, this portion of the homework has been the most difficult for students to implement due to students not fully understanding what’s actually going on when they create pipes. Thus, we highly recommend that you first fully understand how pipes work on a conceptual level before you begin coding. Course staff reserves the right to not help you debug
