Change ebook metadata using filename in command-line mode

hfpop · 02-18-2016, 11:05 AM

I have the following problem: a large number of ebook files with names following a particular metadata naming scheme (for example, "series [nr] author - title.epub")

I need to change the actual metadata of these files using the information given as the filename. Loading the files in Calibre works flawlessly. But I want to try doing this via windows cmd scripting using command-line options.

The actual use of -author and -title options of ebook-meta is problematic in Windows because of unicode issues in cmd.

Is there any possibility to use in cmd line mode features from visual calibre? In particular here, the metadata plugboards.

Metadata plugboards are not supported in "Embed Metadata" or "Polish Book".

I believe there are some tricks for unicode in the CMD on Windows, no idea what though.
Or maybe the Cygwin shell handles unicode properly

I dont understand what your issue with ebook-convert is. If you have a large number fo files, presumably you will want to script the operation. In which case you dont need to care about cmd at all, write your script in any scripting language you like.

Or if you want to use, cmd, set its codepage to utf-8 or use powershell instead.

Under Linux, all is right. Under windows, I tried Perl scripts with cmd in all sorts of combinations. There are various cases where the use of non-English characters is problematic. On the other side, Cygwin does indeed handle unicode properly. But it adds another layer. The right decision is, of course, to abandon Windows and switch to a decent operating system.

The #2 solution is to use Cygwin as a sanity layer for general Windows usage.
