Recursive script to find all epubs in the current dir and subs, then convert to mobi using calibre's ebook-convert utility

finds all epub files in the current directory and all child directories and converts them to .mobi format.

all of the ebook-convert -options are optional; the only parameters you are required to pass are the incoming file and the outgoing file, with the extension.

Has been tested on Ubuntu 10.10

-exec sh -c 'var={}; do something with var' lets you do things in a sub-shell

while it's faster to type, I'm not sure if dozens of subshells execute quicker than the while loops.

Know a better way?

If you can do better, submit your command here.

What others think

Wouldn't it be better to put this in parentheses, so that it doesn't change the user-level working directory?

Why not find . -name *.epub -exec .... ?

Comment by joedhon 109 weeks and 1 day ago

jodehon: Try writing that command with the pattern substitution he's using. It isn't as easy as it looks. SamB: Parens would be good, yes.

Comment by kaedenn 109 weeks and 1 day ago

find . -name '*.epub' -exec sh -c 'a={}; ebook-convert $a ${a%.epub}.mobi' \;

plus the optional parameters.

And it wasn't als easy as it looked. xargs and escaping just didn't do the trick...
