Batch file that checks FTP folder if any file matching a mask exist

Question

I need to create a batch file that goes to a protected FTP site, checks if a file type (*.txt) exists, and if it does, proceed to the next step, if not, return

Answer 1

It's not a trivial task, particularly if you need to check for a file matching a mask (not for a specific file).

You can use WinSCP scripting:

@echo off

set REMOTE_PATH=/home/user/*.txt
winscp.com /command ^
    "open ftp://user:password@host/" ^
    "option failonnomatch on" ^
    "ls %REMOTE_PATH%" ^
    "exit"

if %ERRORLEVEL% neq 0 goto error

echo File(s) matching %REMOTE_PATH% exist
rem Do something
exit 0

:error
echo Error or no file matching %REMOTE_PATH% exists
exit 1

The above code is from the WinSCP article on Checking file existence.
