Re: ISO Image

[Wladimir Foo <wfoo@linuxvoodoo.com>]

Here are a few scripts that might help:

To create an ISO image from a directory:

-----cut-----
#!/bin/sh

DIRECTORY=`echo "$1/" | cut -d "/" -f1`
echo Creating ISO image called "$DIRECTORY".iso...
mkisofs -R -J -l "$1" > "$DIRECTORY.iso"

----end cut---

Just make it executable and run it like this:

./makeiso directory

where directory is where you have your files you want to put on CD. This will 
make an iso with the name directory.iso

Here's another script to burn iso's using cdrecord:

--cut---

#!/bin/sh
cdrecord -eject dev=1,0,0 speed=12 fs=16M -isosize -pad "$1"
sleep 2

--end cut--

Again, make this exe. after you've made changes to reflect your current 
hardware. Use cdrecord --scanbus to see what your dev= settings are and set 
the speed.

If you save this file as burniso.sh, just "burn" a cd with "burniso 
directory.iso".

That's it!

hope this helps,

Wlad.
