_LANGUAGE_ example showing how to retrieve file permissions (via FTP) for each file in a remote directory. Perl

use chilkat();

$success = 0;

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$ftp = chilkat::CkFtp2->new();

# Set the various properties to establish the connection.
$ftp->put_Hostname("ftp.example.com");
$ftp->put_Username("login");

# If SSL/TLS is required..
# See http://www.cknotes.com/determining-ftp2-connection-settings/ 
# for more information.

# Connect to the FTP server:
$success = $ftp->ConnectOnly();
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# Authenticate with the FTP server.
$success = $ftp->LoginAfterConnectOnly();
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# To get file permissions in UNIX format, disallow MSLD:
$ftp->put_AllowMlsd(0);

# To get file and sub-directory information, simply
# loop from 0 to ftp.GetDirCount() - 1
$i = 0;

# The two most common types are "mlsd" and "unix".  See the
# online reference documentation for more information.
