Thanks for What's my MOBI? script!
No need to change anything im almost done making a script automatically using the mobiunpack script and skip calibre entirely for that matter
edit: whatsmymobi script is a GUI one, possible just have a pure command line only like:
whatsmymobi.py /path/to/test.mobi
I realize some people like nice buttons and windows but im quite comfortable doing all from command line, allows for great automation and saves my hands ravaged by years of computer use
I can sort of understand python but coming from C, Java, PHP world its a bit alien
