| # first, we need to determine type of disk | |
| # this can be achieved by trying first mount_cd9660 and checking error | |
| # if it returns "Device not configured" - we need to wait, | |
| # otherwise its not CD9660 fs and we can move to next | |
| # | |
| # try mounting UDF, if it returns "Invalid argument" - it's not an UDF | |
| # | |
| # the last remaining disc type is CD audio disc, that we must | |
| # rip with cdparanoia -B -d /dev/cd0 and then ffmpeg all tracks into mp3 | |
