One can incidentally terminate sushi by pressing Ctrl+C (Ctrl+Break, Command+dot) or a similar combination of keys that sends SIGNIT to the shell. Function prevent_interruption() sets up a signal handler that intercepts SIGINT and displays message “Type exit to exit the shell” on stderr. The name of the handler is refuse_to_die(), its skeleton and the skeleton of prevent_interruption() are provided in sushi.c. Hint: use system call sigaction() to set up the handler. As a result, when you attempt to interrupt the...
1. Explain the difference between the /etc/profile and the ~/.bash_profile file. Which one is executed first? 2. Edit your .bash_profile file as follows: 1. Welcome the user 2. Add your home directory to the path if it is not there 3. Set erase to the Backspace key using stty. 4. Type source .bash_profile. What is the function of the source command? 3. What is the default primary prompt? 1. Change the prompt to include the time of day and your...
Objective : Write a C Shell script which copies all files(*.java and *.class) from your home directory to a new one, and Analyze the new directory information such as number of files, user permissions, and disk usage. Sample Output: << CS Directory Analysis >> Date: ============================================================ Current Directory: /home/tomss New Directory Created : /home/tomss/pgm01 File information Total Number of files : 22 files Directory files: 0 files Plain text files: 10 files File have read permissions: 3 files File have...
Overview Writing in the C language, implement a very basic shell, called smash. In this project, we will work on processing strings and using the appropriate system calls. Build System setup Before we can start writing code we need to get our build system all setup. This will involve writing a very simple makefile. You should leverage your Makefile project for this part of the assignment! Write a Makefile that provides the three targets listed below all - The default...
1. You are given a C file which contains a partially completed
program. Follow the instructions contained in comments and complete
the required functions. You will be rewriting four functions from
HW03 (initializeStrings, printStrings, encryptStrings,
decryptStrings) using only pointer operations instead of using
array operations. In addition to this, you will be writing two new
functions (printReversedString, isValidPassword). You should not be
using any array operations in any of functions for this assignment.
You may use only the strlen() function...
You should test out your script using the following matrices. 2 3 1 2 3 1 C D- 3 2 B- A- -3 8 4 8 2 4 4 1 You may not use any special MATLAB tools. Instead, work symbolically and derive general expressions for the eigenvalues and the eigenvectors. For instance, you may not use the SOLVE function. If you are not sure whether or not a particular function is available to you, just ask Include your hand...

Game Description: Most of you have played a very interesting game “Snake” on your old Nokia phones (Black & White). Now it is your time to create it with more interesting colors and features. When the game is started a snake is controlled by up, down, left and right keys to eat food which appears on random locations. By eating food snake’s length increases one unit and player’s score increases by 5 points. Food disappears after 15 seconds and appears...
