I would like to know how to loop through each line in a text file using a Windows batch file and process each line of text in succession. I have a text file containing filenames.

What I'd like to do is something like 

for x in textFile
    "python C:\main.py -s x"  # the command i want to run

  • What have you tried, and what have you searched for? This is an extremely easy task in batch that has been documented... basically everywhere. – SomethingDark Apr 22 '15 at 03:14

for /f %%x in (textFilename) do python C:\main.py -s %%x

would be the classic method - as a batch file.

reduce %% to % throughout if you are running directly from the prompt

or, more fully,

for /f "usebackqdelims=" %%x in ("textFilename") do python C:\main.py -s "%%x"

  • Don't forget to include `"delims="` to grab the entire line, and `"usebackq"` in case the file path has a space in it somewhere. – SomethingDark Apr 22 '15 at 03:33
