Word, Character, Line Counter Ruby Script

I've been on a few projects lately that involve loading data files that I get from other teams. When I get a file, it's nice to see how big it is to get an idea of how long it will take. Opening the file in a text editor and going to end of file to see the row number can be a pain, especially for big files. Also, I'm on a Windows desktop, so tools like "wc" aren't built-in, and launching Cygwin and getting to the right directory can be a pain in itself (cd /cygdrive/c/Documents\ and\ Settings/ran488/Desktop), so I whipped up this quick Ruby script to give me all the file info I want.

Here's the Ruby script (fileinfo.rb) to get the count of lines, characters, and words in a text file. It also spits out the min and max line size as well. The source can be downloaded at http://www.frontiernet.net/~nicholson150/fileinfo.rb.

#!/usr/bin/env ruby if __FILE__ == $0 if ARGV.length < 1 then puts "Usage: #{$0} filename" exit end results = [] words = 0 chars = 0 minline = 0 maxline = 0 filename = ARGV.first File.new(filename, "r").each { |line| results << line } puts "#{filename} has..." puts " -> #{results.size} lines." results.each do |line| chars += line.length words += line.split.length if line.length > maxline then maxline = line.length elsif line.length < minline then minline = line.length end end puts " -> #{words} words." puts " -> #{chars} characters." puts " -> #{minline} character shortest line length." puts " -> #{maxline} characters longest line length." end

Here's an example of the output....

C:\cvs\MqThrottler>fileinfo.rb PA_CSS_Test_Load_0911.txt PA_CSS_Test_Load_0911.txt has... -> 10008 lines. -> 58021 words. -> 4356721 characters. -> 0 character shortest line length. -> 489 characters longest line length.
