Demonstrates the Chilkat Ftp2.AppendFile method, which appends the contents of a local file to a remote file. The first argument is the local file path and the second is the remote file path. It uses the FTP APPE command.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

local chilkat = require("chilkat")

-- Demonstrates the Ftp2.AppendFile method, which appends the contents of a local file to a remote
-- file.  The 1st argument is the local file path and the 2nd is the remote file path.

local ftp = chilkat.Ftp2.new()

ftp.hostname = "ftp.example.com"
ftp.username = "myFtpLogin"

-- Normally you would not hard-code the password in source.  You should instead obtain it
-- from an interactive prompt, environment variable, or a secrets vault.
ftp.password = "myPassword"

local success = ftp:connect()
if not success then
    print(ftp.last_error_text)
    return
end

-- Uses the FTP APPE command.  On a server with normal APPE behavior, a missing remote file is
-- created; otherwise the local bytes are appended to the end of the existing remote file.
success = ftp:append_file("qa_data/today.log", "logs/app.log")
if not success then
    print(ftp.last_error_text)
    return
end

print("Appended to the remote file.")

success = ftp:disconnect()
if not success then
    print(ftp.last_error_text)
    return
end
