Hello,
I have a header which I have to add to a sorted file, however if I use
cat header sortedfile > newfile, the operation takes 2 minutes as the sorted file is over 400mb.
I have noticed that when I sort the 400mb unsorted file, this only takes 14 seconds to create the output.

So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

Net::LDAP::Control::Sort(3) User Contributed Perl Documentation Net::LDAP::Control::Sort(3)NAME
Net::LDAP::Control::Sort - Server Side Sort (SSS) control object
SYNOPSIS
use Net::LDAP::Control::Sort;
use Net::LDAP::Constant qw(LDAP_CONTROL_SORTRESULT);
$sort = Net::LDAP::Control::Sort->new(
order => "cn -phone"
);
$mesg = $ldap->search( @args, control => [ $sort ]);
($resp) = $mesg->control( LDAP_CONTROL_SORTRESULT );
print "Results are sorted
" if $resp and !$resp->result;
DESCRIPTION
"Net::LDAP::Control::Sort" is a sub-class of Net::LDAP::Control. It provides a class for manipulating the LDAP Server Side Sort (SSS)
request control 1.2.840.113556.1.4.473 as defined in RFC-2891
If the server supports sorting, then the response from a search operation will include a sort result control. This control is handled by
Net::LDAP::Control::SortResult.
CONSTRUCTOR ARGUMENTS
order
A string which defines how entries may be sorted. It consists of multiple directives, separated by whitespace. Each directive describes
how to sort entries using a single attribute. If two entries have identical attributes, then the next directive in the list is used.
Each directive specifies a sorting order as follows
-attributeType:orderingRule
The leading "-" is optional, and if present indicates that the sorting order should be reversed. "attributeType" is the attribute name
to sort by. "orderingRule" is optional and indicates the rule to use for the sort and should be valid for the given "attributeType".
Any one attributeType should only appear once in the sorting list.
Examples
"cn" sort by cn using the default ordering rule for the cn attribute
"-cn" sort by cn using the reverse of the default ordering rule
"age cn" sort by age first, then by cn using the default ordering rules
"cn:1.2.3.4" sort by cn using the ordering rule defined as 1.2.3.4
METHODS
As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the
current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.
