What you might be looking for in this thread. Just also download the 2010 annual manually to get everything. https://ia800204.us.archive.org/29/items/Dungeon_Magazine_An...

  until [ $i -gt 221 ]
  do
    printf -v j "%03d" $i
    wget "https://archive.org/download/Dungeon_Magazine_$j/Dungeon_Magazine_$j.pdf"

There's a Python library:

https://archive.org/services/docs/api/internetarchive/

And script:

https://archive.org/services/docs/api/internetarchive/cli.ht...

Which really helps you automate stuff.

https://pypi.org/project/internetarchive/

It turns your script into:

    for i in $(seq 1 221)
    do
        ia download Dungeon_Magazine_$(printf "%03d" $i) --glob='*.pdf'
    done

Try 'ia help download' for more information.

   printf -v j  <-- what is this magic that sets the variable $j ?

The printf being called here is the Bash builtin, which has the type signature:

    printf [-v var] format [arguments]

Yes I had to try it out.

I would have been surprised if /usr/bin/printf could do that (and it could not)
