Downloading and Extracting the source code (UNIX 2)

Downloading source code
For this example, we will download a piece of free software that converts between different units of measurements.
First create a download directory
% mkdir download
Download the software here and save it to your new download directory.

Extracting the source code
Go into your download directory and list the contents.
% cd download
% ls -l
As you can see, the filename ends in tar.gz. The tar command turns several files and directories into one single tar file. This is then compressed using the gzip command (to create a tar.gz file).
First unzip the file using the gunzip command. This will create a .tar file.
% gunzip units-1.74.tar.gz
Then extract the contents of the tar file.
% tar -xvf units-1.74.tar
Again, list the contents of the download directory, then go to the units-1.74 sub-directory.
% cd units-1.74
