Problem
You intend to find the length of the longest line in a text file.
Solution
You can use this simple Ruby script as template:
#!/usr/bin/env ruby maxLength = 0 numLines = 0 #Iterate over each line in STDIN STDIN.read.split("\n").each do |line| if line.length() > maxLength maxLength = line.length() end numLines += 1 end #Print what we calculated puts "Maximum line length: #{maxLength} in #{numLines} lines"
