I clearly see that /tmp/sipfile has

user1
user2
user3
user4

and I see end of line($) through vi...

but when I run the script, it shows the entire /etc/passwd file in /tmp/result.

what am I doing wrong??

#!/usr/bin/perl -w

open(SIPFILE, "</tmp/sipfile");
open(RESULT, ">>/tmp/result");

while (<SIPFILE>) {
chomp;
$line = `grep \$_ /etc/passwd`;
print RESULT $line;
}

close(SIPFILE);
close(RESULT);

setmaillist

setmaillist(1)						      General Commands Manual						    setmaillist(1)

NAME

       setmaillist - create a binary mailing list

SYNOPSIS

       setmaillist bin tmp

DESCRIPTION

       setmaillist reads a mailing list from its standard input.

       setmaillist writes the mailing list in a binary format to tmp; it then moves tmp to bin.  tmp and bin must be on the same filesystem.

       If there is a problem creating tmp, setmaillist complains and leaves bin alone.

       The binary mailing list format is portable across machines.

       setmaillist always creates bin world-readable.

MAILING LIST FORMAT

       The mailing list read by setmaillist is a series of lines.  NUL bytes are not allowed.

       If a line begins with a dot or slash, setmaillist takes the entire line as an include file name.

       If  a line begins with an ampersand, setmaillist takes the rest of the line as a recipient address.  If a line begins with a letter or num-
       ber, setmaillist takes the entire line as a recipient address.  Each recipient address must include a fully qualified domain name.  Recipi-
       ent addresses longer than 800 bytes are not allowed.

       setmaillist ignores blank lines and lines beginning with #.  It also ignores spaces and tabs at the ends of lines.

       For example,

	  god@heaven.af.mil
	  djb@silverton.berkeley.edu

       is a mailing list with two addresses.
