Many thanks for this post. There's a little problem with this solution. If the ldif is very big the array could collapse the memory. In my case the ldif allocates 70 gb os disk space, so the script with the array crash.

In this case I would prefer this script:

#!/usr/bin/perl

while ($line = <>) {
chomp($line);
if ( $line =~ /^authpassword/ ) {
next;
} elsif ( $line =~ /^\S+/) { ### this line is a "normal" or starting line
print "$complete_line\n";
$complete_line=$line;
} elsif ( $line =~ /^$/ ) { ### this line is blank
print "$complete_line\n";
$complete_line="";
} elsif ( $line =~ /^\s+(\S.*)/ ) { ### this line is a continuation
$line =~ s/^\s+//;
$complete_line=$complete_line . $line;
}
}

This script can be run in a pipe, like this:

# gzcat backup_ldif.gz | ./concat_ldif.pl

I was having a problem with this script. It doesn't handle the situation where the continuation line contains spaces. Here's a better version:

$cnt=0;
while ($line = <>) {
chomp($line);
if ( $line =~ /^authpassword/ ) {
next;
} elsif ( $line =~ /^\S+/) { ### this line is a "normal" or starting line
$results[$cnt++] = $line;
} elsif ( $line =~ /^$/ ) { ### this line is blank
$results[$cnt++] = "";
} elsif ( $line =~ /^\s+(\S.*)/ ) { ### this line is a continuation
$results[$cnt-1] = $results[$cnt-1] . $1;
}
}

for $i (0 .. $cnt) {
print "$results[$i]\n";
}

Very handy Dan. It hadn't actually occurred to me that you could always use Perl from the Oracle home before - I do often find myself having to do some sort of "munging" across multiple lines and Perl is probably the easiest tool for the job.
