From FLAC to MP3|OGG|OPUS, using avconv:

input="file.flac"
# → MP3
output="${input%flac}mp3" # remove 'flac', append 'mp3'
avconv -i "$input" -ab 256k "$output"
# → OGG
output="${input%flac}ogg"
avconv -i "$input" -acodec libvorbis -aq 100 "$output"
# → OPUS
output="${input%flac}opus"
avconv -i "$input" -f wav - | opusenc --bitrate 256 - "$output"
