Software applications and operating systems usually represent a newline with one or two control characters:
* Systems based on ASCII or a compatible character set use either LF (Line feed, 0x0A) or CR (Carriage Return, 0x0D) individually, or CR followed by LF (CR+LF, 0x0D0A); see below for the historical reason for the CR+LF convention. These characters are based on printer commands: The line feed indicated that one line should feed out of the printer, and a carriage return indicated that the printer carriage should return to the beginning of the current line.
o LF: Multics, Unix and Unix-like systems (GNU/Linux, AIX, Xenix, Mac OS X, etc.), BeOS, Amiga, RISC OS, and others
o CR+LF: DEC RT-11 and most other early non-Unix non-IBM OSes, CP/M, MP/M, MS-DOS, OS/2, Microsoft Windows
o CR: Commodore machines, Apple II family and Mac OS up to version 9
This thread has many useful comments. However, the OP has not returned to tell what s/he used.
One way to ask these kinds of questions is to include a sample of what the line really looks like, such as:

My small script:

asa
ASA(1) BSD General Commands Manual ASA(1)NAME
asa -- interpret carriage-control characters.
SYNOPSIS
asa [file ...]
DESCRIPTION
The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to
the standard output.
The first character of each line is interpreted as a carriage-control character. The following characters are interpreted as follows:
<space> Output the rest of the line without change.
0 Output a <newline> character before printing the rest of the line.
1 Output a <formfeed> character before printing the rest of the line.
+ The trailing <newline> of the previous line is replaced by a <carriage-return> before printing the rest of the line.
Lines beginning with characters other than the above are treated as if they begin with <space>.
EXAMPLES
To view a file containing the output of a FORTRAN program:
asa file
To format the output of a FORTRAN program and redirect it to a line-printer.
a.out | asa | lpr
DIAGNOSTICS
The asa utility exit 0 on success, and >0 if an error occurs.
SEE ALSO f77(1)STANDARDS
The asa utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
