leave the script as it was and replace tmp.dat with the path to the file you wish to extract the records from

Skrynesaver,

Wow, wonderful!!!!!!! It worked Smilie Smilie Smilie Thanks.

Now here you hardcoded the file name, suppose ie we have to modify the script which picks the file from a particular directory with particular file name pattern one by one, what changes needs to be done?

Thanks,
Bharath.

change it into a Perl script that iterates over the supplied arguments eg:
Code:
#!/usr/bin/perl

use strict;
use warnings;
for my $filename (@ARGV){
  my $file_counter=0; 
  my $in_record=0; 
  open (my $file "<" $filename);
  while($file){ 
    s/\*/|/g; 
    s/~/\n/g; 
    if(/^ST/){ 
      $in_record=1; 
      open (my $outfile, ">" , "$filename.$file_counter"); 
    } 
    print $outfile $_ if $in_record; 
    if (/^SE/){ 
      close $outfile; 
      $in_record=0; 
      $file_counter++; 
    } 
  }
  close $file;
}

and call it with the list of files you wish to split as arguments

Skrynesaver,
The script that you gave is throwing error when adding any unix commands. If I need to change it unix script what should I do it so that I can also include the basic unix commands like echo etc.

for echo use [code]print[/icode] to run commands use the quote executable syntax qx($command) if you wish to capture the output of a command you can assign the output of the quoted executable eg.
Code:
perl -e '$output=qx(ls $ENV{HOME}/tmp);print $output'
tmp.pl
tmp.dat
tmp.sh
