Editing ID3 tags from command line using Python.

You can build a Python module from scratch just to edit ID3 tags, but there is no need to reinvent the wheel since there are many modules ready for this job.I have been using http://id3-py.sourceforge.net which is very straightforward , anyway, here is a little How-to
* Download the module and extract it to any directory you like
* Navigate to the directory where you extracted the module to

cd /ID3/id3-py-1.2

*Install the module

sudo python setup.py install

* If there is no errors , you are ready to go.
download this python script created by the same author ,
http://id3-py.sourceforge.net/ID3/id3-tagger.py
make it executable

chmod  a+x id3-tagger.py

 , you can copy the file to the home directory for an easier access
we are almost done,
here is an example on how to use the file

find ./ -d 1 -name '*.mp3' -exec ~/id3-tagger.py -A 'soundcloud' {} \;

this command will search for any mp3 file in the directory [not recursively] , then will modify the Album tag to soundcloud , you can modify/add different tags to the command as you wish.

Bash Script To Extract Subtitles From MKV file.

well ,some times I prefer to do things using the command line ,especially when logging into my server remotely ,so I created a little bash script to help me extract subtitles from mkv files using mkvextract ( you have to install  mkvtoolnix-cli) , still , the file extension need to be added though.
