How to view and edit ISO Volume Label with command

Rex Ai · Jan 19, 2011

I know using mkisofs to create an iso file:

Code:

mkisofs -JR -V MYLABEL -o myiso.iso /mydir/

How can I view and edit MYLABEL to another label name with command (not gui)?

Thanks!

Edit iso file with editor?

If it is already burned stuff are more complicated.

NO, view and modify the Volume Label of the iso file before burning under ttyv*(not Xï¼‰.

Where in richardpl's answer did you see he was proposing the use of X-based tools?

You can edit binary files using text-based hex editors, such as editors/hte. Just search the label, modify it and save the file.

Now you probably meant you want an *automated* tool and *not just text-based*. I don't think there's one. But you can always code a patcher in C. Just some basic file I/O and you're done.

I investigated this a few years ago and came back with nothing.

I had a big stack of DVDs, and I wanted to script copying them to disk, in a directory named after the volume name of the disc.

I ended up using this as a workaround.

file(1) will show the volume label in an ISO file.
% file /tmp/FreeBSD-8.2-RC1-i386-livefs.iso

Code:

/tmp/FreeBSD-8.2-RC1-i386-livefs.iso: ISO 9660 CD-ROM filesystem data [B]'FreeBSD_LiveFS                 '[/B] (bootable)

vi(1) can edit it in-place. But you should be concerned about data integrity.

Thanks a lot.

I can use command "file" to view the volume label.

I can use editors/bvi or editors/hexedit to modify the volume label. (notice: only modify the ISO9660 label, not Joliet label)

Under X Windows, I can use sysutils/isomaster to do everything.

It is time to learn sed(1) & awk(1).

Only the GNU versions support a "binary mode", no?

sed does not add additional EOF, EOL, not even mentioning formating. And on UNIX there is no distiction between binary and ascii files.

Oopps, just found that one by googling for something I had known but forgot just the same problem. I also found the answer: [CMD="isoinfo"]-d[/CMD] does the exact trick we are looking for. It is a program from the sysutils/cdrtools package.
