How to get a newline when writing file from PC to Linux using Samba

I am trying to write a text file on Unix (via Samba) from a Ruby
program running on the PC. I am trying to get the end of line
correct. I cannot get the Unix newline character (0x0a) in the file.
I am getting the same results when writing to either the PC or Linux
so Samba is not the issue. How do you do this?

tf = "S:/open/test_ending.txt" # Unix
#tf = "C:/temp/test_ending.txt" # PC

fo = File.open(tf, "w")
text = "this is line ending lf-r\r"
fo.write(text) # puts an OD (cr) at end of line
text = "this is line ending crlf\n"
fo.write(text) # puts an 0D0A at end of line
text = "this is line ending 0x0a"
fo.write(text)
fo.putc 0x0a # puts an 0D0A at end of line - Weird
text = "this is line ending 0x0d"
fo.write(text)
fo.putc 0x0d # puts an 0D at end of line
fo.close

# I cannot get a linefeed (newline 0x0a) in the file.
# results of writing to unix and pc are the same.

fo = File.open(tf, "w")

Open your file in binary mode - and you will have what you expect.

"\n" to native newline I/O conversion depends on the runtime platform, which in your case is Unix. In Unix no conversion is needed, so if you print a "\n" in Unix that's what you get (a single character with octal code 012).

To output CRLF, the convention in your _target_ platform, output "\015\012" by hand.

The whole story is explained here

it is Perl-based but what explains applies to Ruby as well (expect perhaps for the corner case of Macs before OSX).
