Wicked Cool Ruby Scripts

File Splitting

File Splitting

fileSplit.rb

A cool use of Ruby scripting is to split a large file into several smaller, symmetric files. I wrote this script for a friend who was having trouble sending files into and out of his corporate network since the network administrators wouldn't allow files over a certain size to be transferred—presumably for bandwidth reasons. This script worked like a charm.

The Code

 if ARGV.size != 2
     puts "Usage: ruby fileSplit.rb <filename.ext> <size_of_pieces_in_bytes>"
     puts "Example: ruby fileSplit.rb myfile.txt 10"
     exit
 end

 filename = ARGV[0]
 size_of_split = ARGV[1]

 if File.exists?(filename) file = File.open(filename, ...
