Count lines

Howto count all lines from stdin or a file in groovy.


This is how this would look for the commandline:

def lines = 0
		System.in.eachLine {
			lines++
		}
		println lines

or for a file
def lines = 0
		def fileName = "file.txt"
		new File(fileName).eachLine {
			lines++
		}
		println lines
