in thread Adding a TAB after a certain ammount of characters

Please show us your perl1.pl script inside <code> and </code> tags so we can see where you are going wrong. As for working on a multi-line file, calculate the offsets, open your file then do something like

while ( <$inputFH> )
{
    foreach my $offset ( reverse @cums[ 1 .. $#cums ] )
    }
        substr $_, $offset, 0, q{-};
    }
    print;
}

I hope this moves you forward.

Update: Code modified to replace for statement modifier with an explicit loop, thanks choroba.

Cheers,

    Now the file looks like this perl1.pl script looks like this (after some modifications I did from reading the replies

     #!/usr/local/bin/perl 
perl -Mstrict -Mwarnings -E 
my $text =
   q{2013020400000000006810083610022013068100200220130688000200494};
my @offs = ( 17, 6, 31, 3, 3 );
my @cums = ( 0 );
push @cums, $_ + $cums[ -1 ] for @offs;
substr $text, $_, 0, q{-} for reverse @cums[ 1 .. $#cums ];
say $text;

    And the reply I get from running the script is:

    biancoari@biancoari ~/Desktop $ perl perl1.pl
    syntax error at perl1.pl line 2, near "E
    my "
    Execution of perl1.pl aborted due to compilation errors.

    I will add the

    open(FILE, "filename.txt") or die "Could not open file: $!"

    and modify the text, any idea if I am heading the right direction?

      You need to remove the second line alltogether. 

      perl -Mstrict -Mwarnings -E

      Replace the second line 
      perl -Mstrict -Mwarnings -E

      which is for the shell with equivalent Perl lines: 
      use strict;
use warnings;
use feature 'say';

        This is working GREAT!!! 


        #!/usr/local/bin/perl 
use strict;
use warnings;
use feature 'say';
my $text =
   q{2013020400000000006810083610022013068100200220130688000200494};
my @offs = ( 17, 6, 31, 3, 3 );
my @cums = ( 0 );
push @cums, $_ + $cums[ -1 ] for @offs;
substr $text, $_, 0, q{-} for reverse @cums[ 1 .. $#cums ];
say $text;

        Now what is need to do is to modify all the lines of the file, I know that I need to call the file, like this


         open(FILE, "file1.txt") or die "Could not open file: $!";

        Am I heading on the right direction?
