Question

I need to split a file into different ones.

Exmaple (original file):

*****3123123*****RAW
text1
text2
*****2312354***RAW
text3

Desired output:

[File1.txt]

*****3123123*****RAW    
text1
text2

[File2.txt]

*****312312354***RAW
text3

I tried to use split, but I always get some extra white characters into the array

open FILE, "<file";
@file= <FILE>;
close FILE;
@lines = split (/(RAW\n)/, "@file");
foreach $value (@lines) {
  if ($value =~ /[a-z]|[A-Z]|[1-9]/)  {
    print ("$value\n");
  }
}

Output:

*****3123123*****RAW

 text1
 text2

*****312312354***RAW

 text3

Edit: if I use print (“$value”) instead of print (“$value\n”) this is the output (notice the 1 extra space before the value:

*****3123123*****RAW
 text1
 text2

 *****12354***RAW
 text3

This program pulls the decimal number from the RAW line and uses it to name the output files. It expects the input file name as a parameter on the command line.

use strict;
use warnings;

@ARGV or die "Input file required as command-line parameter\n";

my $out;

while (<>) {
  if ( /(\d+)\*+RAW$/ ) {
    open $out, '>', "$1.out" or die $!;
    select $out;
  }
  print $_ if $out;
}
