This script I use will work (FLAC files only) IF you have your files organized by Artist/Album (where each album has its own folder) (not sure how else it could/should be organized)
This script will walk the directory entered in the FIRST line. My files are in ~/Music/FLAC, so starting there will process all FLAC files.
If you want to use this, test on one Album (or Artist) first:
Code:
#!/bin/bash
StartDir=$HOME/Music/FLAC # No trailing slash!
count=0
function walk_tree {
local directory="$1"
local i
for i in "$directory"/*
do
if [ -d "$i" ]; then # Process directory and then walk-down
ls "$i/"*.flac | grep -i -q -s ".flac$" # Does directory contain FLAC files?
if [ $? -eq 0 ] ; then
echo "Adding replay gain tags to:"
for j in "$i/"*.flac
do
echo "$j"
let count++
done
/usr/local/bin/metaflac --preserve-modtime --add-replay-gain "$i/"*.flac
echo "$i done!" # echo directory that we're in
echo $count files processed.
fi
walk_tree "$i" # DO NOT COMMENT OUT THIS LINE!!
else
continue # replace continue with command to process individual file "$i" (i.e. echo "$i")
fi
done
}
# Process FLAC files in starting directory
cd "$StartDir"
ls *.flac | grep -i -q -s ".flac$" # Does directory contain FLAC files?
if [ $? -eq 0 ] ; then
echo "Adding replay gain tags to:"
for j in *.flac
do
echo "$j"
let count++
done
/usr/local/bin/metaflac --preserve-modtime --add-replay-gain *.flac
echo "$StartDir done!" # echo directory that we're in
echo $count files processed.
fi
# Now walk down tree in this directory
walk_tree "$StartDir"
