How do i split a file by newline

[Amit Tomar]

Hi all,
I would like to know how do i split a file by newline ,am
able to do it tab space like

path="E:/expr/amit.txt"
File.open(path).each do |i|
k=i.split("\t" )

puts "#{k[0]}"
end

o/p: amit

and this is content of my file(amit.txt)

amit sumit

now i changed content of file like

amit
sumit

path="E:/expr/amit.txt"
File.open(path).each do |i|
k=i.split("\n" )

puts "#{k[0]}"
end

i should get amit only but am getting
amit
sumit

how do i make them split from newline??

File.open(path).each do |i|
k=i.split("\n" )

puts "#{k[0]}"
end

i should get amit only but am getting
amit
sumit

how do i make them split from newline??

no need to split("\n") because it's allready done :
#! /opt/local/bin/ruby1.9
# encoding: utf-8
k=[]
File.open("amit.txt").each {|l| k<<l }
puts k[0]

here i get amit, the first line.

Thanks frnd
but why split("\n") is not working for me

i think because the :
File.open("amit.txt").each {|l| k<<l }
allready split the content of the file by line, then, no more \n ?
the ".each" here would means each line...

path=3D"E:/expr/amit.txt"
File.open(path).each do |i|
k=3Di.split("\n" )

puts =A0"#{k[0]}"
end

i should get amit only but am getting
amit
sumit

no need to split("\n") because it's allready done :
#! /opt/local/bin/ruby1.9
# encoding: utf-8
k=3D[]
File.open("amit.txt").each {|l| k<<l }
puts k[0]

Even simpler

k =3D File.readlines "amit.txt"
# different separator
# k =3D File.readlines "amit.txt", "\t"

Cheers
