Problem in perl program in printing all the entries
Hi all,

I have a perl program where it checks for the presence of a particular line and prints the record if that line is present. But in the output file, all the entries are not being printed even if the entry has that line. The line to be matched is *FIELD* AV. The program which I wrote is given below. I have no idea where I might be wrong. Any suggestions are welcome. Thanks in advance.

Code:
#!/usr/bin/perl
$/="\n\n";
open(DATA,'mutationsonly.txt');
# or die("Could not open mutationsonly file.");
open(MYOUTPUT, ">newmutations.txt");
# or die ("could not open newmutations file.");
my @records= <DATA>;
close(MYOUTPUT);
close(DATA);
foreach my $record (@records)
{
chomp;
my $find=/^\*FIELD\*\sAV$/;
if ($record=~m/ $find /) 
{
print "$record";
}
}

conflict

conflict(8mh)															     conflict(8mh)

Name
       conflict - search for alias/password conflicts

Syntax
       /usr/lib/mh/conflict [ -help ] [ -mail name ] [ -search directory ] [ aliasfiles ...  ]

Description
       The  program checks to see if the interface between MH and transport system is in good shape.  It also checks for maildrops in which do not
       belong to a valid user.	It assumes that no user name will start with a dot (.)	and thus ignores files in which begin with a dot.

       The program checks the entries in the specified alias files.  It parses the entries in the same way that  would,  and  outputs  any  errors
       which  it  finds.   The	program can be used to check the entries in a user's personal alias file, or in the system alias file, If no alias
       file is specified, checks the system alias file.

       The program also checks the file for entries which do not belong to a valid user, and for users who do not have a valid group  number.	In
       addition, duplicate users and groups are noted.

       The program should be run under or whenever system accounting takes place.

Options
       -help	 Prints a list of the valid options to this command.

       -mail name
		 Mails the results to the specified name.  Otherwise, the results are sent to the standard output.

       -search directory
		 Searches  directories	other than and reports anomalies in those directories.	The -search switch can appear more than once in an
		 invocation to with different directories named.

Files
       The system customization file.

       The system password file.

       The system group file.

       Program used to mail results, if the
		 -mail option is used.

       Directory containing users' maildrops.
