You could use this:
| Code: | data="`dd if=/dev/cdroms/cdrom0 ibs=1024 skip=32 count=1 2>/dev/null`"
echo "Label:" ${data:39:32} |

Wow, that was easy... 
There's got to be a simpler way? |

Put this in a file called getcdlabel (or something similar)
| Code: |
#!/bin/bash
data="`dd if=/dev/cdroms/cdrom0 ibs=1024 skip=32 count=1 2>/dev/null`"
echo "Label:" ${data:39:32}
|
The chmod +x it and put a copy of it in /usr/bin
Then to get the label from a CD just do:
You can even add it to your WM's menu or something
Or there is a program in portage that grabs cd labels that you could just emerge, but I'm not sure what it's called.

Yeah, of course you can put it in a script, but I thought that there has to be some program that already does this? Maybe a switch to mount or something, but I couldn't find any.
But if I put that in a script, then i won't have to worry about it again, so you're right about that  |

There is. I'm sure I've seen one in portage that does this... I just can't remember what it's called... You can try looking through /usr/portage/media-sound it might be in there.
