Lab 1: Introduction to the Labs and UNIX

This first lab is meant as an introduction to the computer environments we will be using this term.  Java programs can be written and run almost anywhere so we will be using the university computers for ease of accessibility.

To login to the computers you will need to use an SSH client to go to javalab.cs.pitt.edu There you will login with your Pitt account (initials followed by a number.)

In this lab you will use these commands to navigate around in the UNIX environment:

Important UNIX Commands

• cd - change directory
• ls - list files in current directory
• pwd - display the current directory
• mv - move or rename a file
• cp - copy a file
• pico - edit a text file
• javac - compile a java file
• java - run a java program

Now that you have heard a little about them, use the commands above to complete this lab:

Lab 1

1. cd to your private directory

2. cp ~jrmst106/public/CS7/Welcome.java .            (notice the period!)

3. javac Welcome.java

4. java Welcome

What is the output? (write it in the space below.)

Hand this in to Rasoul when you are done.
