hi hunt,

Try this, this returns array of the names u asked for,

1.txt

name,rollno,city,country
ABC,123,NewYork,US
XYZ,124,Pittsburg,US
LMN,125,Moscow,RUSSIA
_____________________________________________________



f = File.open('1.txt')
a=[]
b=[]
c=[]
d=[]
f.readlines.each do |lines|
  line_arr = lines.split(',')
  a << line_arr[0].strip
  b << line_arr[1].strip
  c << line_arr[2].strip
  d << line_arr[3].strip
end

a.shift
b.shift
c.shift
d.shift

puts a.inspect
puts b.inspect
puts c.inspect
puts d.inspect
f.close

-------------
output:
["ABC", "XYZ", "LMN"]
["123", "124", "125"]
["NewYork", "Pittsburg", "Moscow"]
["US", "US", "RUSSIA"]

is this u need?
