Procedures

Step 1: Downloading the package from the Internet

4 After a few seconds, the Save as box will appear Make a note the location where the file is being saved so it can be found after being installed Click Ok to

save the file in the default location

Step 2: Unpacking and installing the application

1 In the terminal Window, navigate to the folder where the application was saved It should be the home folder After reaching the correct directory, type ls –bl at the shell prompt

This will list the contents of the directory The downloaded file should be listed in the directory Look for the filename

netscape-i686-pc-linux-gnu-installer.tar.gz That is the name of the file that needs to be unpacked and installed

2 To unpack and install the file, enter the following command at the shell prompt:

tar –xvzf netscape-i686-pc-linux-gnu-installer.tar.gz

This should create a new directory called netscape-installer in the same directory To list the contents of the directory again, use the ls –l command

3 Change to the netscape-installer directory by entering cd

/netscape-installer at the shell prompt

Now use the ls –l command to list the contents of the netscape-installer directory

4 Install the software by entering the following command at the shell prompt:

/root/netscape-installer/netscape-installer This should automatically launch the Netscape installer window Click Next On the following screen, click Accept to accept the license agreement

Click Next again to accept the recommended installation

On the next screen, click on the Install button It will take a few minutes for the

files to download and install Once the status bar shows that the download has been completed, the software should self-install

browser should open When it does, close it

Step 2: Using the new application

Netscape Communicator link This should open the old version of Netscape

Reflection

How does software installation in a Linux system compare to that in a Windows system? Are there any advantages to the way that it is done in a Linux system as opposed to a Windows system?
