Classic FTP - Executing a FTP script
The FTP command support the "-s:ftpscript.txt" option. The FTP commands listed in ftpscript.txt will automatically run after FTP starts. The FTP command can be started from a batch file.Example:
FTP - Simple Single Batch - FTP script and batch in a single file
Embed FTP script into a batch script. Add this line at the beginning of the FTP script:@ftp -i -s:"%~f0"&GOTO:EOF
The "FTP -s:ftpscript.txt" option executes a FTP script wheres "%~f0" resolved to the name of the running batch file. "GOTO:EOF" ends the batch script and makes sure the FTP script doesn`t run as part of the batch.
FTP - Automatic Login - Automatically login to your FTP session with a single click
If you frequently find yourself calling FTP from the command line, each time having to login and change directory and change FTP modes, until you finally get where you want be in order to do some real work then you may wish to get there with a singe click.
This little batch can connect to your FTP server and logs you in before it gives you the prompt. You can easily add more FTP commands to it, like changing directories or switching to binary mode or whatever you like to be done before taking over control on the FTP prompt.
The FTP connection information is embedded within the batch itself. The batch connects to an FTP server by executing itself in FTP context using the FTP -s option. Once executing in FTP context it executes all FTP commands listed in the file. By omitting the final FTP "bye" command it will stop at the FTP prompt and wait for user input.
Optionally a FTP script can be provided as input stream, that way multiple FTP scripts can share the same login information. Example:
|Script:||Download: FtpLogin.bat |
FTP Scripts Sharing Login Info - Manage the FTP login separately from your FTP scripts
If you have multiple FTP scripts that all use the same login information to your FTP site then you may wish to manage the login information separately from your FTP scripts in a single place. That way if the username, password or hostname for the FTP connection changes you only need to edit a single place instead of having to edit all FTP scripts one by one.
This automatic login script (also described in detail earlier) can be used to execute different FTP scripts that share the same login information stored within the batch file.
Example: FtpLogin.bat script1.ftp
Note: The FTP scripts passed into the batch must have the login sequence removed.
Note: The FTP script executes even if the connection sequence fails potentially causing `Not connected` and other errors. This is no different from regularly executing FTP with -s option.

FTP - Resolving Environment Variables - Creating FTP script on the fly at runtime and using variables within the FTP script
This batch executed the FTP script embedded within the batch. All variables in the FTP script will be resolved.
Variables can be used within the FTP script the same way as in a batch script, including any string manipulation and command line arguments like %1 %2 %~n0 %* and so on.
FTP - Download Only New Files - Ftp script to download only files that don`t exist in local folder, i.e. to avoid overwrite
|Description:||This batch connects twice to the FTP server. First time it retrieves a list of files on the FTP server. This list is being trimmed to contain only files that don`t already exist locally. The files in the trimmed list are then downloaded during a second connection.|
Note: Since all files are passed into the FTP`s MGET command there might be a limit to the number of files that can be processed at once.
|Script:||Download: BatchFtpDownloadOnlyNewFiles.bat |
FTP - Upload Only New Files - Ftp script to upload only files that don`t exist in remote folder, i.e. incremental upload
|Description:||This batch connects twice to the FTP server. First time it retrieves a list of files on the FTP server. Local files that are are not in this list will then be uploaded during a second connection.|
Note: Since all files are passed into the FTP`s MPUT command there might be a limit to the number of files that can be processed at once.
