SmartFTP is a fantastic FTP application which handles syncing files very effectively. This means that when you upload your entire website, SmartFTP will automatically detect changes and only upload what is required (instead of overwriting all of the files like some FTP applications do). For each project at TheFARM we have build scripts which run and create a time stamped ZIP package for each deployment environment with all of the necessary files formatted appropriately for each. Our deployment process then involves unzipping the contents of this file, opening up SmartFTP, connecting to the deployment destination and transfering all of the deployment files up (which SmartFTP synchronizes for us).

I thought it would be much more efficient if we automated this process. So we did some investigation and it turns out the SmartFTP conveniently has an API! So we decided to see if we could write a PowerShell script to use the SmartFTP api to automagically transfer/sync all of our deployment files in our Zip package to the necessary FTP site and with a bit of trial and error we managed to do it! Now, I’m not PowerShell expert or anything, and in fact this was my very first PowerShell script ever written so I’m sure this could all be done a bit better, but it works! I’m not going to go into detail about the SmartFTP api or how to write PowerShell stuff because this script will work with some basic requirements:

  • You need both PowerShell and SmartFTP installed
  • Currently this only supports the standard FTP protocol, but if you need SFTP, etc… you can just change the $fav variable’s ‘Protocol’ property
  • The parameters, in this order are:
    • destination
      • the IP address, or host of your FTP server
    • user
      • the username used to login to the FTP server
    • password
      • the password used to login to the FTP server
    • path
      • The FTP path of where you want your files to go on your FTP server
    • port
      • The FTP port to use, default is 21
    • source
      • The source folder to copy to the FTP site, if not specified, uses the current directory that the PowerShell script is run from

Example usage:

FTPSync.ps1 123.123.123.123 MyUserName MyPassword 21 “C:\MyWebsiteFolder” “/websites/MyWebsite”

or you can just double click on the ps1 file and it will prompt you for these details.

So without further adieu, here’s the script!
