Running WinSCP command from Python

Question

I have created the following command file with name submitCmd.txt:

open myname@ftpclients.myserve.com -privatekey=C:\Users\Mike\Desktop\uploader\mykey.ppk
put C:\Users\Mike\Desktop\uploader\files2Upload\myFile.xlsx /mnt/data/myFolder/
close
exit

When I run the above script from command line as:

winscp.com /script=C:\Users\Mike\Desktop\uploader\submitCmd.txt

It runs successfully.

However, when I try the following in python:

cmdFile = r'C:\Users\Mike\Desktop\uploader\submitCmd.txt'
import subprocess
subprocess.run(["winscp.com", "/script=", cmdFile], shell=True)

I get the error:

Searching for host...
Host "C" does not exist.

Answer 1

Your command will run WinSCP like this:

winscp.com /script= C:\Users\Mike\Desktop\uploader\submitCmd.txt

What is an invalid syntax. There cannot be the space after the /script=.

This should work:

subprocess.run(["winscp.com", "/script=" + cmdFile], shell=True)
