combine multiple lines

Hi I have a file and I need to combine the lines

example:

From this

START=so_documentation Upd so_doc_source=M so_module=AGENT_LOG_ROLLOVER so_doc_\
START=type=Module


to this

START=so_documentation Upd so_doc_source=M so_module=AGENT_LOG_ROLLOVER so_doc_type=Module

Not sure the code would be since on multiple lines.

There could be multiple lines as the text wraps at 8 characters.
Its basically un-wraping the lines.

Thanks

Mike

This may not be the most elegant code (it is the first perl script I've ever written), but it appears to work with data based on the pattern of the limited sample you provided...

use strict;
use warnings;

my $filein    = 'datain.txt';
my $fileout   = 'dataout.txt';

my $newline   = '';
my $firstpart = '';
my $lastchar  = '';
my $firstequal = 0;
my $state      = 0;
my $backslash  = "\\";
my $trash      = '';

open(my $fhin, '<:encoding(UTF-8)', $filein)
  or die "Could not open file '$filein' $!";

open(my $fhout, '>:encoding(UTF-8)', $fileout)
  or die "Could not open file '$fileout' $!";

while (my $row = <$fhin>) {
  chomp $row;
  $firstequal = index $row, '=';
  $firstequal++;
  $lastchar = substr $row, -1;

  $state = 0;
  if (($newline eq '') && ($lastchar ne $backslash)) {
    $state = 1;
     }
  if (($newline eq '') && ($lastchar eq $backslash)) {
     $state = 2;
     }
  if (($newline ne '') && ($lastchar ne $backslash)) {
     $state = 3;
     }
  if (($newline ne '') && ($lastchar eq $backslash)) {
     $state = 4;
     }

  if ($state == 1) {
     print $fhout $row . "\n";
     }

  if ($state == 2) {
     $trash = chop($row);
     $newline = $newline . $row;;
     }

  if ($state == 3) {
     $firstpart = (substr $row, $firstequal);
     print $fhout $newline . $firstpart . "\n";
     $newline = '';
     }

  if ($state == 4) {
     $firstpart = (substr $row, $firstequal);
     $trash = chop($firstpart);
     $newline = $newline . $firstpart;
     }
}

close $fhout;
close $fhin;
