 var fs = require('fs')  

 var contents = fs.readFileSync(process.argv[2])  
 var lines = contents.toString().split('\n').length - 1  
 console.log(lines)  

 // note you can avoid the .toString() by passing 'utf8' as the  
 // second argument to readFileSync, then you'll get a String!  
 //  
 // fs.readFileSync(process.argv[2], 'utf8').split('\n').length - 1
