Assignment Help:

Your shell should accept and execute the pipe "|"  operator. This will look like the following:

/home/ p r o j e c t s / cs200 / spring12 / shell >cat project2.c | grep include

#includ e

#includ e

#includ e

#includ e

#includ e

/home/ p r o j e c t s / cs200 / spring12 / shell >
