This is my chance to ask a last [ or one-of the last ]
question[s].
Now that I have
cdr.iso: ISO 9660 CD-ROM filesystem data 'CDROM
642848 -rw-r--r-- 1 kline wheel 657922048 Jan 24 15:34 cdr.iso
what is the safest command to use to burn to 1. a CD, and 2. a
DVD? Since `file' says that cdr.iso is a filesystem, I'm
assuming that I don't need to grow or newfs anything on the disc.
cdrdao seems like more toward audio, so i'm guessing that it's
either cdrecord or burncd. I'll share my shell script once it
works on both media.
