[Need help] perl script to find the occurance of string from a text file
I have two files
1. input.txt
2. keyword.txt

input.txt has contents like

Code:
.src_ref 0 "call.s" 24 first
      0x000000    0x5a80 0x0060         BRA.l 0x60
.src_ref 0 "call.s" 30 first
      0x000002    0x1bc5                RETI
.src_ref 0 "call.s" 31 first
      0x000003    0x6840                MOV R0L,R0L
.src_ref 0 "call.s" 35 first
      0x000004    0x1bc5                RETI

keyword.txt has contents

Code:
MOV
BRA.l
RETI
ADD
SUB
..
etc

Now I want to read this keyword.txt file and search it in input.txt file and find how many times MOV has occured,how many times BRA.l has occured and so on.

So far I have managed to get it working from a single file itself. here is the code

Code:
#!/usr/bin/perl
use strict;
use warnings;

sub retriver();

my @lines;
my $lines_ref;
my $count;
$lines_ref=retriver();
@lines=@$lines_ref;
$count=@lines;
print "Count :$count\nLines\n";
print join "\n",@lines;

sub retriver()
{
    my $file='C:\Users\vk41286\Desktop\input.txt';
    open FILE, $file or die "FILE $file NOT FOUND - $!\n";
    my @contents=<FILE>;

    my @filtered=grep(/MOV R0L,R0L/,@contents);
    return \@filtered;
}

here i can search only MOV and i am unable to search other instructions like RETI.

I am a newbie on perl and this is not a assignment problem.

OUTPUT should be

Code:
MOV has occured 2  times
RETI has occured 1 time

Thanks for help/guide.

HTML Code:
P.S : This question was posted on stackoverflow and all I could get is bash script , single command line. 

But what I need to perl script.

locale::script

Locale::Script(3perl)					 Perl Programmers Reference Guide				     Locale::Script(3perl)

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. The ones currently supported are:

       alpha
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       numeric
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Script::delete_script  ( CODE [,CODESET] )
       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
