By 'by itself' I mean

Code:
du Documents

Just that, only that, nothing but that.

When it says 'file not found', it almost certainly means what it says -- there's nothing named 'Documents' in the current directory for it to measure the size of.

What does the output of ls look like?

NAME
NET::LDAP::DSML -- A DSML Writer for Net::LDAP SYNOPSIS
For a directory entry; use Net::LDAP; use Net::LDAP::DSML; use IO::File; my $server = "localhost"; my $file = "testdsml.xml"; my $ldap = Net::LDAP->new($server); $ldap->bind(); # # For file i/o # my $file = "testdsml.xml"; my $io = IO::File->new($file,"w") or die ("failed to open $file as filehandle.$! "); my $dsml = Net::LDAP::DSML->new(output => $io, pretty_print => 1 ) or die ("DSML object creation problem using an output file. "); # OR # # For file i/o # open (IO,">$file") or die("failed to open $file.$!"); my $dsml = Net::LDAP::DSML->new(output => *IO, pretty_print => 1) or die ("DSML object creation problem using an output file. "); # OR # # For array usage. # Pass a reference to an array. # my @data = (); $dsml = Net::LDAP::DSML->new(output => @data, pretty_print => 1) or die ("DSML object cration problem using an output array. "); my $mesg = $ldap->search( base => 'o=airius.com', scope => 'sub', filter => 'ou=accounting', callback => sub { my ($mesg,$entry) =@_; $dsml->write_entry($entry) if (ref $entry eq 'Net::LDAP::Entry'); } ); die ("search failed with ",$mesg->code()," ") if $mesg->code(); For directory schema; A file or array can be used for output, in the following example only an array will be used. my $schema = $ldap->schema(); my @data = (); my $dsml = Net::LDAP::DSML->new(output => @data, pretty_print => 1 ) or die ("DSML object creation problem using an output array. "); $dsml->write_schema($schema); print "Finished printing DSML "; DESCRIPTION
Directory Service Markup Language (DSML) is the XML standard for representing directory service information in XML. At the moment this module only writes DSML entry and schema entities. Reading DSML entities is a future project. Eventually this module will be a full level 2 consumer and producer enabling you to give you full DSML conformance. Currently this module has the ability to be a level 2 producer. The user must understand the his/her directory server will determine the consumer and producer level they can achieve. To determine conformance, it is useful to divide DSML documents into four types: 1.Documents containing no directory schema nor any references to an external schema. 2.Documents containing no directory schema but containing at least one reference to an external schema. 3.Documents containing only a directory schema. 4.Documents containing both a directory schema and entries. A producer of DSML must be able to produce documents of type 1. A producer of DSML may, in addition, be able to produce documents of types 2 thru 4. A producer that can produce documents of type 1 is said to be a level 1 producer. A producer than can produce documents of all four types is said to be a level 2 producer. CALLBACKS
The module uses callbacks to improve performance (at least the appearance of improving performance ;) and to reduce the amount of memory required to parse large DSML files. Every time a single entry or schema is processed we pass the Net::LDAP object (either an Entry or Schema object) to the callback routine. CONSTRUCTOR
new () Creates a new Net::LDAP::DSML object. There are 2 options to this method. "output" is a reference to either a file handle that has already been opened or to an array. "pretty_print" is an option to print a new line at the end of each element sequence. It makes the reading of the XML output easier for a human. Example my $dsml = Net::LDAP::DSML->new(); Prints xml data to standard out. my $dsml = Net::LDAP::DSML->new(output => @array); my $dsml = Net::LDAP::DSML->new(output => *FILE); Prints xml data to a file or array. my $dsml = Net::LDAP::DSML->new(output => @array, pretty_print => 1); my $dsml = Net::LDAP::DSML->new(output => *FILE, pretty_print => 1); Prints xml data to a file or array in pretty print style. METHODS
start_dsml () Start a DSML file. end_dsml () End a DSML file. write_entry ( ENTRY ) Entry is a Net::LDAP::Entry object. The write method will parse the LDAP data in the Entry object and put it into DSML XML format. Example my $entry = $mesg->entry(); $dsml->write_entry($entry); write_schema ( SCHEMA ) Schema is a Net::LDAP::Schema object. The write_schema method will parse the LDAP data in the Schema object and put it into DSML XML format. Example my $schema = $ldap->schema(); $dsml->write_schema($schema); AUTHOR
