Estou vendo o contador de Hardware_ECC_Recovered aumentando e diminuindo nas estatísticas SMART de um disco rígido e estou confuso.

Eu esperaria que aumentasse cada vez que um erro fosse detectado (e corrigido) pelo ECC, mas por que diabos isso diminuiria?

Eu tenho muitos (cerca de 6000!) mp3s que gostaria de despejar em subdiretórios, com base no nome do arquivo. Atualmente eles estão todos em um único subdiretório. (Já existem alguns diretórios existentes para alguns artistas, não desejo tocar nos arquivos neles, no entanto, uma duplicata sobrescrevendo um arquivo existente é aceitável).

A maneira mais simples que vejo de fazer isso é criando um subdiretório com base no nome do arquivo, já que os arquivos são todos denominados artist.artist.album.track.mp3.

Depois de algumas pesquisas cheguei a:

for x in ./*.mp3; do awk x="${x}" -F. '{split(x,a,"."); mkdir a[1]; mv x a[1]/}'; done

No entanto, ele me diz que há um erro de sintaxe e regexp não terminado:

awk: cmd. line:1: x=./Dizzee.Rascal.Radio.1.Live.Lounge.03.That.s.Not.My.Name.mp3
awk: cmd. line:1:   ^ syntax error
awk: cmd. line:1: x=./Dizzee.Rascal.Radio.1.Live.Lounge.03.That.s.Not.My.Name.mp3
awk: cmd. line:1:     ^ unterminated regexp
awk: cmd. line:1: x=./Dizzee.Rascal.Ultimate.Streetdance.CD1.03.Flex.Dave.Spoon.Mix.mp3
awk: cmd. line:1:   ^ syntax error
awk: cmd. line:1: x=./Dizzee.Rascal.Ultimate.Streetdance.CD1.03.Flex.Dave.Spoon.Mix.mp3
awk: cmd. line:1:     ^ unterminated regexp

Acho que é porque o nome do arquivo não é fornecido entre marcas de fala, mas não tenho 100% de certeza.

Alguém pode ajudar - e pontos de bônus se você conseguir imprimir o progresso também.
