Hi rammm,

One way using perl:
Code:
$ head sec.txt disp.txt 
==> sec.txt <==
3172

==> disp.txt <==

the file name is
***********
45676
$ cat script.pl
use warnings;
use strict;

my @nums;

while ( <> ) {
        chomp;
        if ( m/\A\d+\Z/ ) {
                push @nums, $_;
                close $ARGV;
        }
}

if ( @nums >= 2 ) {
        printf qq[%s\n], ($nums[0] == $nums[1]) ? q[Equal] : q[Not equal];
}
else {
        printf qq[Error\n];
}
$ perl script.pl sec.txt disp.txt 
Not equal

mlib_SignalAutoCorrel_S16(3MLIB)			    mediaLib Library Functions				  mlib_SignalAutoCorrel_S16(3MLIB)

NAME

       mlib_SignalAutoCorrel_S16, mlib_SignalAutoCorrel_S16S, mlib_SignalAutoCorrel_F32, mlib_SignalAutoCorrel_F32S - signal auto-correlation

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalAutoCorrel_S16(mlib_d64 *correl, const mlib_s16 *src, mlib_s32 disp, mlib_s32 n);

       mlib_status mlib_SignalAutoCorrel_S16S(mlib_d64 *correl, const mlib_s16 *src, mlib_s32 disp, mlib_s32 n);

       mlib_status mlib_SignalAutoCorrel_F32(mlib_d64 *correl, const mlib_f32 *src, mlib_s32 disp, mlib_s32 n);

       mlib_status mlib_SignalAutoCorrel_F32S(mlib_d64 *correl, const mlib_f32 *src, mlib_s32 disp, mlib_s32 n);

DESCRIPTION

       Each of these functions performs auto-correlation.

       For monaural signals, the following equation is used:

		     1	  n-d-1
       correl[0] = ----- * SUM (src[i] * src[i + d])
		   n - d   i=0

       For stereo signals, the following equation is used:

		     1	  n-d-1
       correl[0] = ----- * SUM (src[2*i] * src[2*(i + d)])
		   n - d   i=0

		     1	  n-d-1
       correl[1] = ----- * SUM (src[2*i + 1] * src[2*(i + d) + 1])
		   n - d   i=0

       where d = disp.

PARAMETERS

       Each of the functions takes the following arguments:

       correl	       Pointer	to  the  auto-correlation array.  In the stereo version, correl[0] contains the auto-correlation of channel 0, and
		       correl[1] contains the auto-correlation of channel 1.

       src	       Source signal array.

       disp	       Displacement.  0 <= disp < n.

       n	       Number of samples in the source signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

ATTRIBUTES
