Subject: "chomping" an array at read time

Team,

ruby -v =3D=3D=3D ruby 1.8.2 (2004-12-25) [powerpc-aix4.3.3.0]

Please don't laugh at my simplistic coding "techniques?"


I am reading a file which contains 1041 one token records into an array:

f_lus =3D File.open("/file_name", "r")

lus =3D Array.new
lus =3D File.read("/file_name")

When I print the size of the array lus it shows: 14377.

So I figured that this has to do with the end of line chars at the end of
each record/token. However, if you have 1 nl char per record the size shoul=
d
be twice the number of records or 2082 and not 14,377.

I went ahead and created a new array as follows, from the old array in the
same script:

i =3D 0
newArray =3D Array.new
lus.each do |lu|
  newArray[i] =3D lu
  i +=3D 1
end

Now when I puts the size of array newArray it prints 1041 correctly.

What is happening here, please?
Second, is there a way to chomp a record as it is read into the array?

Thank you

Victor
