True... but I only use calibre portable even on Windows, since I cannot install stuff on the occasional Windows computers I use.
Then again, I also don't bother with portableizing calibre's library folders across linux computers (though it is backed up on the flashdrive
) in favor of doing it with Dropbox and similar solutions.
... And just for fun, I gave a shot at updating it.
I added a few tricks like offering a list of directories to check for (it should use the first directory that exists) and updated to proper bash-isms.
