Homework 0

Due: Monday, January 10, at 11:00pm

This assignment lays the foundation for the rest of the course. In it you will demonstrate that you can log into at least one course Linux system and execute basic shell commands. Students will submit their work via Gradescope, which will automatically check the submission. Students are encouraged to resubmit until they earn all 10 available points for HW 0.

Requirement Specifications

For this assignment you must use either your account on the cancun.cs.washington.edu machine or your own copy of the CSE Linux Virtual Machine (VM). It is possible to use another reasonably recent Linux system for many things, but we will use the CSE systems to evaluate submitted work, and you need to verify that everything you submit works correctly there. See the Linux Resources page on the course web site for more information about how to get started.

(Shell) You must be sure that your default shell is bash. Otherwise you will run into strange, baffling problems with shell scripts. Enter the command echo $SHELL. The response should be /bin/bash. If the shell name is different (csh, tcsh, or something else), use the appropriate commands on your system to change your login shell to bash. On many Linux and Unix systems this can be done with the command chsh or ypchsh.
(Commands) Open a shell window and enter the following commands. They should work without errors if typed exactly as shown. (Note: You will start your session in your home directory. You may wish to change directories before you get started. On the VM you can use the Desktop by entering cd Desktop, or on any system you may wish to make a 374 directory and work there. You can do this by entering
```
    mkdir cse374
    cd cse374 
```
. The script command will capture the terminal session and save it in a file named hw0.script in the current directory.
```
 
   script hw0.script
   echo $SHELL
   whoami    
   pwd
   uname -a
   gcc --version -std=c11
   exit
```

Assessment

This assignment is worth 10 points - 2 points for each command. As this is a foundational assignment you are encouraged to resubmit until you earn a perfect score. Hint: The scriptcommand records everything, even backspaces. If you have too many corrections there will be a lot of extraneous characters if your hw0.script file that may interfere with the autograder. In this case, repeat the exercise carefully avoiding extra key strokes.

Turning In

Please submit to the Gradescope HW0 assignment. This is linked through Canvas, or you can go directly through Gradescope. You should submit one file, called hw0.script.
