I'm pretty new to bash scripting so some of the stuff is simple, most aren't.
What I'm looking for is a script that will read all my mp3 tags within a directory using id3info and rewrite them with a predefined format using id3tag.
What I do is move a group of mp3s to a directory named
couch'compilation or such, then I have to manually change the id3 tags on each one to include the artist in the title, rename the album to the directory name and change the artist to me and strip the current track number.
What I've got so far pretty much doesn't do anything.
Code:
#!/bin/bash -
#
# convert title to artist - title
#
function year {
id3info "$i" | grep TYER | cut -d":" -f2 | sed 's§ §§'
}
function genre {
id3info "$i" | grep TCON | cut -d":" -f2 | sed 's§ §§'
}
function title {
id3info "$i" | grep TIT2 | cut -d":" -f2 | sed 's§ §§'
}
function artist {
id3info "$i" | grep TPE1 | cut -d":" -f2 | sed 's§ §§'
}
function album {
id3info "$i" | grep TALB | cut -d":" -f2 | sed 's§ §§'
}
function track {
id3info "$i" | grep TRCK | cut -d":" -f2 | sed 's§ §§'
}
function bit {
id3info "$i" | grep Bitrate | cut -d":" -f2 | sed 's§ §§'
}
function freq {
id3info "$i" | grep Frequency | cut -d":" -f2 | sed 's§ §§'
}
for i in *.mp3
do
nice -n 19 id3tag -2 --song='$artist" - "$title' "$i"
done
and the output from id3tag and id3info
Code:
couch[test]$ id3info *.mp3
