Answer 1

All it does is upload a bunch of images that match a certain filename mask to a remote server and stores the curl output in a log file, then renames those images when they've been processed.

But since that answer is short and boring, I'll go through the script line by line.

setlocal

Sandboxes the variables that get set in the script so that they can't be accessed once the script ends. Not necessary, but good practice.

SET tmpfile="temp3.txt"

Sets a variable called tmpfile to the value temp3.txt .

for %%f in (FY2?_20??.JPG) do (

Iterates over the list of every JPG file in the current directory that starts with FY2 , then some character, then _20 , then two more characters.

    curl --form image=@%%f http://www.test.com/images/image_upload.php>%tmpfile%

Uploads each image to www.test.com via that site's image_upload.php page. The output of the curl command gets redirected to the file whose location got stored in the %tmpfile% variable earlier. > says to overwrite the contents of the file or create a new file if one does not exist. The --form option makes curl send the image via POST rather than GET.

    REN "%%f" "DONE-%%f"

Appends the string "DONE-" in front of the current file name

    REN %tmpfile% "%%f.log"

Changes the name of the log file to match the name of the file that was just uploaded. This line tells me that the %tmpfile% variable is redundant and the curl output could simply have been redirected to %%f.log without needing a temporary file.

This just closes the for loop.
