Hi! First post here. I'm interested in using the bash shell to script the conversion of my epub files to mobi. Right now I have this working:

Code:

for f in *.epub; do ebook-convert "$f" "`basename "$f" .epub`.mobi"; done;

This works fine, but it only operates on one epub at a time. In the Calibre GUI it seems to run up to 3 conversions at once. Is there a way using the command line to run ebook-convert in parallel? I have a quad-core iMac, which could blow through these much faster in parallel.

Thanks for any suggestions,
Joe

p.s. I'm on Mac OS X 10.7.4, using Calibre 0.8.53.
