How to use a Batch to run a python script and then run that python script on multiple files

Question

I would like to know that how can a BATCH file be configured to first run a python script: example.py (to do a find and replace) and then run the script on multiple files in sub folders with in a root folder.

Also the files edited/changed in the sub folders should be deleted and saved with the new changed file.

Your help will be much appreciated.

Thanks in advance.

You could start with something like this:

for /r [[drive:]path] %a in (*.txt) do example.py "%a"

this executes example.py for every .txt file, starting from [[drive:]path], and recursing subdirectories /r. If you omit drive:path it will start the search from the current directoty, e.g.

for /r %a in (*.html) do example.py "%a"
for /r C:\ %a in (*.html) do example.py "%a"

The first example executes example.py for every *.html file under current dir, the second one executes example.py for every .html file under C:\.

It is also possible to delete changed files, but we need to have some more information. Maybe you just need this?

for /r %a in (*.txt) do example.py "%a" temp.tmp & copy temp.tmp "%a"

Remeber that this works if you launch this command at the command prompt. If you want to use it inside a batch file (.cmd, .bat) you have to use %%a instead of %a.
