HowTo
flac2mp3.sh:

#!/bin/bash

DESTDIR=$1
PRESET=$2

if test "x$PRESET" = "x"; then
PRESET=standard
fi

if test "x$DESTDIR" = "x"; then
DESTDIR=.
else
mkdir -p "$DESTDIR"
fi

echo
echo "Preset=$PRESET Destination=$DESTDIR Source=`pwd`"
echo

for a in *.flac
do
OUTF=`echo "$a" | sed s/\.flac/.mp3/g`

echo
echo "Source=`pwd`/$a Destination=$DESTDIR/$OUTF"
echo

ARTIST=`metaflac "$a" --show-tag=ARTIST | sed s/.*=//g`
TITLE=`metaflac "$a" --show-tag=TITLE | sed s/.*=//g`
ALBUM=`metaflac "$a" --show-tag=ALBUM | sed s/.*=//g`
GENRE=`metaflac "$a" --show-tag=GENRE | sed s/.*=//g`

echo "Launching: flac -c -d $a | lame --preset $PRESET - $DESTDIR/$OUTF"
echo

flac -c -d "$a" | lame --preset $PRESET - "$DESTDIR/$OUTF"

echo
echo "Setting id3 ($TITLE, $TRACKNUMBER, $ARTIST, $ALBUM, $GENRE, $YEAR)"
echo

if test "x$TITLE" != "x"; then
id3v2 -t "$TITLE" "$DESTDIR/$OUTF" > /dev/null
fi

if test "x$TRACKNUMBER" != "x"; then
id3v2 -T "$TRACKNUMBER" "$DESTDIR/$OUTF" > /dev/null
fi

if test "x$ARTIST" != "x"; then
id3v2 -a "$ARTIST" "$DESTDIR/$OUTF" > /dev/null
fi

if test "x$ALBUM" != "x"; then
id3v2 -A "$ALBUM" "$DESTDIR/$OUTF" > /dev/null
fi

if test "x$GENRE" != "x"; then
id3v2 -g "$GENRE" "$DESTDIR/$OUTF"
