why am I losing line-end chars
Hello,
I do not know why the output from these two methods differs. One method retains the newlines, the other method appears to ignore or lose the newlines.
Writing a file with the redirection operator:
egrep -e 'matchstring' infile.txt > outfile.txt
The resulting outfile.txt contains separated line when viewing the file.
However, when I do this method (with the goal of having all the output lines in a variable called OUTFILE), the resulting text appears to have lost all the line breaks:
OUTFILE=$(egrep -e 'matchstring' infile.txt)
Thank you!

nl(3XCURSES) X/Open Curses Library Functions nl(3XCURSES)
NAME
nl, nonl - enable/disable newline control
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int nl(void);
int nonl(void);
DESCRIPTION
The nl() function enables the handling of newlines. The nl() function converts newline into carriage return and line feed on output and
converts carriage return into newline on input. nonl() disables the handling of newlines.
The handling of newlines is initially enabled. Disabling the handling of newlines results in faster cursor motion since X/Open Curses can
use the line-feed capability more efficiently.
RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR.
ERRORS
None.
