matrixmadhan -
I find some minor problem on the code. It should search for the exact file pattern.

In my example below:

record1
mary MI_AP
anne MI_RC

record2
role1 MI_AP_REC
role2 MI_AP MI_RC

output of the current code:
mary role1 role2
anne role2

Is it possible that it should only search for exact word so the output will be (below) ..?

mary role2
anne role2

clamav-unofficial-sigs(8)					  SCRIPT COMMANDS					 clamav-unofficial-sigs(8)

NAME

       clamav-unofficial-sigs - Download, test, and install third-party ClamAV signature databases.

SYNOPSIS

       clamav-unofficial-sigs [options]

DESCRIPTION

       clamav-unofficial-sigs  is  a  shell script that updates the Sanesecurity, SecuriteInfo, MalwarePatrol, OITC, INetMsg and ScamNailer third-
       party signature databases for ClamAV.

OPTIONS

       This script follows the standard GNU command line syntax.  A summary of the options is shown below.

       -b     Add a bypass signature entry to local.ign in order to temporarily resolve a false-positive issue with a third-party signature.   The
	      script  will monitor any entries it makes to local.ign and will automatically remove bypass entries if either the original signature
	      has been modified or removed from the database.

       -c FILE-NAME
	      Source configuration information from a different file.

       -d     Decode a hexadecimal encoded string or an individual ClamAV 3rd-party signature for viewing.  This will not decode image	signatures
	      nor the official signatures.

       -e     Encode a entire input string in hexadecimal for signature usage in any *.ndb database.

       -f     Encode a formated input string in hexadecimal that contains spacing field '{}, (), *', without encoding the spacing fields, for sig-
	      nature usage in any '*.ndb' database.

       -g FILE-NAME
	      Verify the GPG signature for a specific SaneSecurity database file.  Only specify the filename as listed in the  configuration  file
	      and the script will search for it in the work directory.

       -h     Print the script help and usage information.

       -i     Print system and script configuration information.

       -m     Make  a hexadecimal signature database file (*.ndb) from a clear text ascii file.  Provides support for both full and formatted sig-
	      natures.	Additional information is provided when using the flag.

       -r     Remove the clamav-unofficial-sigs script and all of its associated files, databases and work directories from the system.

       -s FILE-NAME
	      Test the integrity of a third-party signature database with clamscan.  Only specify the filename as listed in the configuration file
	      and the script will search for it in the work directory.

       -t     If  HAM  directory  scanning is enabled in the script's configuration file, then output the names of any third-party signatures that
	      triggered during the HAM directory scan.

       -v     Print the script version and date information.
