Dear All,
Thanks for your replies, codes and advices.
My main problem is I am very new in programming. I am trying to learn. So I am not habituated with either perl or python. Both are new to me. Can anybody please help me to understand how should I make this files executable, like a script, which I can call afterwords? Suppose if I call the script like code.perl or code.anything else
Everytime I want to give ./code.perl input.txt
My 1st try was:
Code:
#!/usr/bin/perl -w

$#ARGV==1 or die "Usage: 2ndprocess-script 1st-output-file-as-inputfile\n";

$name=shift;

$inputfile="`pwd`/$name";

perl -ne '{$/=""; $i=1;
  while (/^Taxonomy:.(.*?)\+{11}/msgi) {
    $x = $1; $x =~ s/(^|\n)\s+/\1/g;
    open(OUT,">outfile".$i++.".txt"); print OUT $x; close(OUT);
  }}' inputfile;

and 2nd try was:
Code:
#!/usr/bin/perl -w

$#ARGV==1 or die "Usage: 2ndprocess-script 1st-output-file-as-inputfile\n";

$name=shift;

$inputfile="`pwd`/$name";

open $fh,"<", $inputfile;
my ($flag,$n)=(0,0);
while(<$fh>){
	if(/Taxonomy:/){
		$n++;
		$file=sprintf("outfile%s.txt",$n);
		open FH,"+>$file";
		$flag=1;
		next;
	}
	if(/\++/){
		$flag=0;
		next;
	}
	print FH $_ if $flag==1;
}

But both of them didn't work in a desired way.
Can anybody please help me?
With best regards and many thanks,
Mitra.

create_sysfile

create_sysfile(1M)														create_sysfile(1M)

NAME

       create_sysfile - create a kernel system file

SYNOPSIS

       [outfile]

DESCRIPTION

       The command creates a kernel configuration description file (system file) which can be used as input to the commands kconfig(1M) or mk_ker-
       nel(1M).  The system file that is generated is of type version 1 (see system(4)) and is built according to the drivers required by the cur-
       rent system hardware.  This command is intended for use during the install process when the system does not have a system file.

       The  command uses the ioscan(1M) command to scan the system hardware and adds all drivers it can identify to run the existing hardware.	If
       outfile is specified, the resulting system file is sent to outfile.  If outfile is not specified, the output is placed in the file

RETURN VALUE

       Upon completion, returns with one of the following exit values:

	      0      Successful.

	      1      One or more errors were reported.

DIAGNOSTICS

       Errors are sent to stderr.  Most of the diagnostic messages from are self-explanatory.  Errors cause to halt immediately.

WARNINGS

       is obsolete and will be removed in a future version of HP-UX.
