@eschwartz:

Unfortunately, your script doesn't work, because kindlestrip.py requires two parameters: the original file and the stripped file. It also doesn't work with file names that contain spaces.

This script actually works:

#!/bin/bash

# IFS change for file names with spaces in them
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

# delete old log
rm -f conversion.log

# process all .mobi files in folder
for i in *.mobi; do
  python kindlestrip.py "$i" ${i%%.*}.new
  ret=$?
	if [ $ret -ne 0 ]; then
		echo "$i" was NOT stripped >> conversion.log
	else
		rm $i
		mv ${i%%.*}.new  ${i%%.*}.mobi
		echo "$i" was stripped >> conversion.log
	fi
done

# restore default IFS
IFS=$SAVEIFS

@Thalia Helikon: You no longer need to use kindlestrip.py, because there's a recently discovered undocumented kindlegen parameter that'll prevent kindlegen from attaching the source files, -dont_append_source. You could use it in a shell script file to convert multiple .epubs with KindleGen:

#!/bin/bash

# IFS change for file names with spaces in them
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

# delete old log
rm -f conversion.log

# process all .epub files in folder
for i in *.epub; do
  kindlegen -dont_append_source "$i" >> conversion.log
  ret=$?
	if [ $ret -ne 0 ]; then
		echo "$i" was NOT compiled. Error code: $ret >> conversion.log
	fi
done

# restore default IFS
IFS=$SAVEIFS

(Of course, you'll also need to copy the kindlegen binary to ~/bin (or create a symbolic ink) and make the shell script executable.)
