Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# 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")
ftp.put_Password("password")

# If SSL/TLS is required..
# See http://www.cknotes.com/determining-ftp2-connection-settings/ 
# for more information.
ftp.put_AuthTls(true)
ftp.put_PassiveUseHostAddr(true)

# Connect to the FTP server:
success = ftp.ConnectOnly()
if (success != true)
    print ftp.lastErrorText() + "\n";
    exit
end

# Authenticate with the FTP server.
success = ftp.LoginAfterConnectOnly()
if (success != true)
    print ftp.lastErrorText() + "\n";
    exit
end

# To get file permissions in UNIX format, disallow MSLD:
ftp.put_AllowMlsd(false)

# To get file and sub-directory information, simply
# loop from 0 to ftp.GetDirCount() - 1
i = 0
n = ftp.GetDirCount()
if (n < 0)
    print ftp.lastErrorText() + "\n";
    exit
end

# Show the type of permissions information that is available.
# The two most common types are "mlsd" and "unix".  See the
# online reference documentation for more information.
if (n > 0)
    print "The permissions format is: " + ftp.getPermType(0) + "\n";
end

while i < n

    # Display the permissions and filename
    print ftp.getPermissions(i) + " " + ftp.getFilename(i) + "\n";

    i = i + 1
end

# Assuming MLSD was possible, let's see the file permissions in MLSD format:
ftp.put_AllowMlsd(true)

# Clear the directory cache so we're forced to re-fetch the directory listing:
ftp.ClearDirCache()

n = ftp.GetDirCount()
if (n < 0)
    print ftp.lastErrorText() + "\n";
    exit
end

# Show the type of permissions information that is available.
# The two most common types are "mlsd" and "unix".  See the
# online reference documentation for more information.

    # Display the permissions and filename
    print ftp.getPermissions(i) + " " + ftp.getFilename(i) + "\n";
