Convert all m4a files into mp3's in a directory:
IFS=$(echo -en "\n\b");for i in *.m4a; do name=`echo $i | cut -d'.' -f1`; echo $name; ffmpeg -i $i $name.mp3; done
@nayafia at medium.com has been blogging about open source infrastructure projects and the posts so far have been interesting.
I added these to my .bashrc:
alias volumedown='amixer -D pulse sset Master 5%-' alias volumeup='amixer -D pulse sset Master 5%+'
For reducing and increasing the volume.
