Using forks from shell
Mi ricordo di aver visto diversi anni qualcosa di simile su NTFS, la cosa sembrava interessante. Generamente invece tendi ad odiare questo tipo di cose perche’ non sono facilmente compatibili con la rete. Osx crea dei files aggiuntivi (che iniziano per ._) quando si copia un file su una condivisione che non supporti le resforks.

Some script involving find, “comm -12″, and those two files you made in the ‚Ä®first part. Maybe “comm” won’t recognize the lines if they’re at different ‚Ä®offsets…
