Also one more question.

I have file on server something.txt, and there are few lines:

name1
name2
name3
#EOF

And if I use sockwrite -n $sockname $str($crlf, 2) it will return all lines without last one #EOF, but if I use
sockwrite -n $sockname $crlf $crlf it will result a bunch of HTML tags and data from file also.

Is there a good explanation of using $crlf?
