I don’t know about that but you can add an “Open In Terminal” entry.

Open a terminal and type in:

mkdir ~/bin/
gedit ~/bin/animecheck

Copy/Past the script in there, save, exit, go back to the terminal and make the script executable:

chmod 755 ~/bin/animecheck

Like Xiong suggested, add the ~/bin/ folder to your PATH:

echo 'export PATH=${HOME}/bin:${PATH}' >> ~/.bashrc

Now install nautilus-open-terminal:

sudo aptitude install nautilus-open-terminal

Log out and log back in. Now you can browse to your Anime folder, right-click, click on “Open In Terminal” then type in:

animecheck *

Copy the script into a text file, save (preferably as something.py), then run it. For instance, if I had saved it as foo.py in ~/bin, and I was in a directory with a bunch of Matroska files I wanted to check, I’d run

python ~/bin/foo.py *.mkv

Alternatively, if you give the script executable permissions (chmod +x foo.py), then you can just run it like so:

~/bin/foo.py *.mkv

and, if ~/bin is in your PATH,

foo.py *.mkv
