Labs, and assignments for this course. This is for educational purposes only. Beware that there may contain mistakes.

Assignment1

Process Creation and Inter-Process Communication

Practice process creation and communication in Linux using fork() and exec() system calls. Wrote a C program dp (standing for double pipe) with the following command syntax: dp program1 : program2 : program3 .

1. program2 is executed with the standard input coming from the standard output of program1
2. program3 is executed with the standard input coming from the standard output of program1
3. program2 and program3 do not divide the output of program1 among themselves, they both get the full output of program1

Assignment 2
