Repo for C programs and ShellScripting
Project 1: Shell Scripting:
Part 1: CPU Utilization
This program prompts the user to enter the I/O fraction time (p) (in the range from 0 to 1) and checks if the input is valid or not. If not, asks the user to re-enter. Then the program prompts the user to enter the expected CPU utilization (in the range from 0 to 1) and checks if the input is valid or not. If not, asks the user to re-enter. Finally it prints out the minimum number of processes (integer) to achieve this goal.
Part 2: Process Scheduling:
This program prompts the user to enter the number of jobs (without checking for input error, it assumes that user inputs a valid integer from 0 to 10). Then the program prompts the user to enter the run time for each job (in seconds) Finally it prints out the order of jobs using Shortest Job First (SJF) scheduling.
Project 2: fork() child processes and Fibonacci in C:
This program implements process creation (creating multiple children processes to work under one parent process) and termination on a Linux platform. In theory, children processes can do their own work separately or cooperatively to accomplish a task. In this program, these children processes perform independent tasks: they simply print out a “my id: ” message together with their PIDs (process IDs) and the Fibonacci result on modulo 20 of their PIDs and then exits.
Project 3: List Linux Command in C:
This program implements a simplified version of the list utility on Linux system. The list of files is printed out in tree format.
