Check Kindle eBook DRM

[CRussel]

Given that it's a Python script, it's trivial to get that script to loop through a list of files. I haven't looked at Paul's script, but if you have problems getting it to work on multiple files, I'm confident that someone can help with that.

Hmm.. come to think of it, it probably now needs updating for Print Replica and KF8 files... always something new!

Thanks for that Paul. Is there a way to do more than one file or must they be done individually.

Two other thoughts (I'd do one or both myself if I were a python programmer):

1. add multiple file capability, text file output and a gui.
2. add multiple file capability and make it a Calibre plug-in.

Also distribute it in Tools.

The problem (as I see it) is a lot of people who have only really used a GUI get lost with a command line (CMD, Shell, etc.). What someone needs to do is give the OP a step-by-step including CDing to the correct directory where the eBooks live. Just giving the command to run won't help since the OP doesn't even know how to get to the proper directory.

If you have a Mac, you can use the Applescript wrapper and drag & drop as many as you like at once, or even just the folder containing the ebooks.

On Windows or Linux, you'd have to write some kind of batch file wrapper.

Am on Windows 7. I tried

c:\drm check>drmcheck.py "c:\ebooks\*.*"

but I guess that was wrong.

Try:

echo off
for %a in (c:\ebooks\*.*) do kindledrm "%a"
echo on

Yeah, I tried "*.azw" and it was no good, I don't think either the script or python likes "*". It said 'NOT MOBI', whatever that means?!

That worked like a champ. So in addition to that how can one redirect the output to a text file?

Try this:

echo off
for %a in (c:\ebooks\*.*) do kindledrm "%a" >> out.txt
echo on

NOTE: I don't have windows, so I'm just guessing. It should work, but I can't guarantee it.

First off, the command needs to be 'kindledrm.py' (forgot to mention this earlier).

The redirect operator needs to be a single '>', not '>>'.

When it is done the output text file only has the last of the processed file listed, so I assume that its re-writing the file on each pass of the loop instead of appending to it.

Yes, because you're using ">" instead of ">>"

OK. Exactly what did you type in the cmd line. I'm not having any luck.

I got an error with that so I tried the single and it worked like I said. I suppose the error was complaining that the output file didn't exist, however it created one. Then it it kinda' worked.

Anyway, now it works like a champ,

This woke the decades old programming part of my brain, at least a tiny bit.

Tried this

C:\Users\Carol\DRM Check>drmcheck.py "c:\ebooks\%a"
Traceback (most recent call last):
File "C:\Users\Carol\DRM Check\drmcheck.py", line 211, in <module>
sys.exit(main())
File "C:\Users\Carol\DRM Check\drmcheck.py", line 113, in main
infileobject = file(infile,'rb')
IOError: [Errno 2] No such file or directory: 'c:\\ebooks\\%a'

What am I doing wrong.
