Linux script to display Some information of MP3 files

 The following bash script utilizes mediainfo command line to retrieve various metadata inside an MP3 (or any media file, in fact):

#!/bin/sh

i=0
for f in "$@"
do
    i=$((i+1))
    printf "%d," $i
    mediainfo --Inform="General;%CompleteName%,%Format%,%OverallBitRate_Mode%,%BitRate%,%FileSize/String4%" "${f}"
done

For example (I put the above into a script named 'bitrate.sh'):

$ bitrate.sh *.mp3
1,01_-_bohemian_rhapsody_-_queen_-_greatest_hits_cd1.mp3,MPEG Audio,CBR,256000,10.94 MiB

3,07_-_it's_a_hard_life_-_queen_-_greatest_hits_cd2.mp3,MPEG Audio,CBR,256000,7.620 MiB
4,09_-_who_wants_to_live_forever_-_queen_-_greatest_hits_cd2.mp3,MPEG Audio,CBR,256000,9.075 MiB
5,11_-_the_miracle_-_queen_-_greatest_hits_cd2.mp3,MPEG Audio,CBR,256000,9.002 MiB

8,16_-_we_will_rock_you_-_queen_-_greatest_hits_cd1.mp3,MPEG Audio,CBR,256000,3.741 MiB
9,17_-_we_are_the_champions_-_queen_-_greatest_hits_cd1.mp3,MPEG Audio,CBR,256000,5.542 MiB

The output is in CSV, suitable to be imported as a table in spreadsheet.
