Command Line DVD Burn Command?

Dear Wise & Powerful Masters of Technolgy,

What would be the best way to get a DVD to burn from command line? I can make a tar & put it on the DVD. But I have not yet figgured out how to make the DVD driver burn automatically.

The objective is to automate backup to DVD. I would like to have a burned DVD will all my stuff from yesterday on an ejected DVD when I walk into the office in the mornings.

Your humble geek,

Kurt

Hi Kurt,

I've been using hdiutil to create data DVDs. I first create an image with hdiutil makehybrid. There's an option for makehybrid that lets you specify a folder for the source files. Then burn the resulting file with hdiutil burn.

Dear Cole,

Thank you for the hint. So far, I have this result:

$ hdiutil burn Desktop/backup
hdiutil: burn: "Desktop/backup" not recognized - No such file or directory
hdiutil: burn failed - No such file or directory

$ hdiutil burn Desktop/backup.fpbf/
hdiutil: burn: "Desktop/backup.fpbf/" not recognized - not recognized
hdiutil: burn failed - not recognized

$ hdiutil burn Desktop/backup/ibook.tar.Z
hdiutil: burn: "Desktop/backup/ibook.tar.Z" not recognized - No such file or directory
hdiutil: burn failed - No such file or directory

$ hdiutil burn Desktop/backup.fpbf/ibook.tar.Z
hdiutil: burn: "Desktop/backup.fpbf/ibook.tar.Z" not recognized - not recognized
hdiutil: burn failed - not recognized

What would you recommend as the next step?

Your humble geek,

Kurt

Hi Kurt,

Hdiutil burn expects a disk image file complete with a file system. You'll need to create this first with hdiutil makehybrid or hdiutil create.

There're many options, so it may be worth while to check out man hdiutil.

Hello,

I prefer makehybrid since the resulting cdr can be used on windows if need be.
