How do I use the firstLine argument in eachLine

Question

I can't seem to make eachLine skip the first line, according to this there is an integer argument that can be passed to eachLine but I can't figure out the syntax

http://groovy.codehaus.org/groovy-jdk/java/io/File.html#eachLine(int,%20groovy.lang.Closure)

#doesn't work
new FileReader('myfile.txt').eachLine firstLine=2,{
       line-> println line
}
#nope
new FileReader('myfile.txt').eachLine(2){
       line-> println line
}

I think you are misunderstanding what the 'firstLine' parameter is used for. From the docs:

firstLine - the line number value used for the first line

Basically this means that this number will identify what the first line is. It always goes through each line in the file.

So for the following code:

new FileReader('c:/users/chris/desktop/file.txt').eachLine(4){line, number-> 
    println "$number $line"
}

It would print out:

4 line1

5 line2

6 line3
