Not exactly what I mentioned.
Of course any DOS command prints its output with "\r\n", whereas UNIX delims
with "\n".
The difference is that gawk doesn't scan its input - when it is redirected
via a pipe -
whether it is a DOS or UNIX textfile and doesn't do a internal conversion of
the lines delimiters.
Let me explain it a little bit more clearly (see my former example):
C:\TEMP\foo>dir /b | gawk '{print $0 $0}'
==> prints it output with "\r"; e.g.
bar_1
C:\TEMP\foo>dir /b > foo
C:\TEMP\foo>gawk '{print $0 $0}' < foo
==> print it output correctly; e.g.
bar_1bar_1
