File Decompression

File Decompression

decompress.rb

This script shows you the basics of decompressing a file. The rubyzip library does all of the work for you. On a standard Unix-like system, you would have to manually unzip the file, carry out your task, and then re-compress the file. With rubyzip, you can work with files in an archive using one seamless library. This script completely decompresses an archive into the user-specified directory.

The Code

 require 'zip/zip'
 require 'fileutils'

 unless ARGV[0]
     puts "Usage: ruby decompress.rb <zipfilename.zip>"
     puts "Example: ruby decompress.rb myfile.zip"
     exit
 end

 archive = ARGV[0].chomp

 if File.exists?(archive) ...
