Linux & Vim Lab #1 – Exercises

Getting Starting with LABS:

1. Power-up your computer
2. Connect to PSU’s network (PSU or PSU Secure) using your CS login and password
3. PC using Windows:
   1. Install ssh or putty
   2. Double click on the ssh or putty icon
   3. For putty, experiment with different colors and text sizes (Window – Appearance)
   4. Use Host name of cs162lab.cs.pdx.edu if you are in CS162. Otherwise, use the appropriate host name for your class.
      • CS162 labs will use cs162lab.cs.pdx.edu
      • CS163 labs will use cs163lab.cs.pdx.edu
      • CS202 labs will use cs202lab.cs.pdx.edu
      • CS299 labs will use cs299lab.cs.pdx.edu
   5. Open a session and login
4. MAC OS X Only:
   1. Open Finder and navigate to Applications.
   2. In Applications, navigate to Utilities.
   3. Find Terminal and double-click it.
   4. Use Host name of cs162lab.cs.pdx.edu if you are in CS162. Otherwise, use the appropriate host name for your class as described earlier.
   5. Once you have a Terminal open, simply type (using the correct host:
      ssh username@cs162lab.cs.pdx.edu
5. Linux Only:
   1. Open Terminal (control t on PSU’s chromebooks)
   2. Use Host name of cs162lab.cs.pdx.edu if you are in CS162. Otherwise, use the appropriate host name for your class as described earlier.
      • CS162 labs will use cs162lab.cs.pdx.edu
      • CS163 labs will use cs163lab.cs.pdx.edu
      • CS202 labs will use cs202lab.cs.pdx.edu
      • CS299 labs will use cs299lab.cs.pdx.edu
   3. Type at the linux prompt based on the class you are in:
      ssh username@cs162lab.cs.pdx.edu
6. Navigate to the directory for the first lab
   • CS162 Students: cd CS162/Lab1
   • CS163 Students:cd CS163/Lab1
   • CS202 Students:cd CS202/Lab1
   • CS299 Students:cd CS299/Lab1
7. Now, create a program get familiar with a linux editor, C++ compiler that we will be using, and how to run a program. Enter in the following program using one of the following editors:
   • CS162 students may use: nano, pico, vi, vim or emacs
   • CS163, CS202, and CS299 students need to use: vi, vim or emacs

Start by editing a C++ file: nano cs162_lab1.cpp


Type in the following sample program using a linux editor

//My name:_______________
//Sample program to get familiar with linux
#include <iostream>
using namespace std;
int main()
{
 //Output a message to welcome the user!
 cout << “Welcome to Computer Science!”;
 return 0;
}

8. When done entering the program, save your work.
   • We recommend saving work frequently
   • Start small and incrementally build your programs
   • Never write more than a single function without compiling and running your program!
9. Compile your C++ source code file. “No news is good news!”
   g++ cs*_lab1.cpp
   
10. If there are errors, use the editor again to modify your program
11. Once the errors are corrected, save your work and exit the editor
12. Re-compile your C++ program: g++ cs*_lab1.cpp
13. Once there are no compile errors, run your program by typing:
    

    ./a.out

14. Submit your program by typing ./submit from the Lab1 directory
