Preparing your Bash Shell

Shells are an important concept in Unix. There are many different shells out there so it's important to find one you're comfortable with. We use the Bourne-Again Shell (BASH) so that's what most of these instructions will be geared towards.

-        See if you have a .bashrc file in your login directory. If not, simply create an empty one.

-        To invoke the bash shell simply type bash at the prompt of the shell you are in. That will execute the commands in .bashrc file.

-        Follow the next set of directions to modify your .bashrc file.

Setting up Java, ANT, and JUnit

Ant is a Java-based build tool that makes managing and building your Java projects MUCH easier. For more details on Ant, make sure you check out the Ant User's Manual. The Ant setup script calls the setup script for the Java 1.5.0_06 JDK so all we have to do is call the Ant setup script in our .bashrc file. Junit is a testing framework for Java programs. It is used for unit testing Java programs; you will be doing a lot of unit testing in class.

• Using your favorite Unix text editor (pico, vi, or emacs) open your .bashrc file.
  For example, using emacs, type:
  >emacs ~/.bashrc  
• Copy the following and paste it at the bottom of your .bashrc file (it's ok if your .bashrc file is empty):

#export  JAVA_HOME=/usr/usc/jdk/1.5.0_06

export  JAVA_HOME=/usr/usc/jdk/default
export  PATH=/usr/usc/ant/default/bin:$PATH

export CLASSPATH=$CLASSPATH:/home/scf-22/csci201/junit4.5/junit-4.5.jar
ulimit -v 1840000

• To be safe, logout and log back in. Or you could try typing:
  >source ~/.bashrc
• To see if you installed Java correctly, type:
  java -version
  You should see a message reading java version "1.5.0_06" or something similar.
• To see if you set up Ant/Java correctly, type:
  >ant
  You should see a message saying that build.xml does not exist. That means Ant and Java are installed and working correctly.
• Junit is properly installed if the "ant test" target runs successfully. You'll do it in lab another time.
