The following code for basic. It will work for only one file. If you need to implement for all files.

Code:
use strict;
use warnings;

open FH,"<file" or die "Can't Open $!";
my @array;
while(<FH>)
{
    push(@array,$_);
}
my $var=$#array+1;
close FH;
open FH,">file" or die "Can't Open $!";
print FH "$var\n";
print FH "@array";

Bug

Use the following script for getting the line count of the each file in a directory in head of the each file.

Code:
for file in `ls .`
do
if [ -f $file ]
then
var=`wc -l $file | cut -d ' ' -f 1`
`sed -i "1i \$var" $file`
fi
done
