Programming and Scripting :: ISO image maker



First I just thought to add an alias, but then I found myself scripting...

In case anyone finds this useful... Does it work on DSL?
Code Sample
#!/bin/bash

# Bash script for making CD-images out of files and/or directories easily.
# Burned images should work with old CD drives as well with new ones
# and with many OS:es too.
# May not work if you specify multiple files/directories to add... But should.;)

I'd add a size limit there if I knew the precise size of 650Mb CD. Anyone know this?
Or any other suggestions?
I found a quite good page about the actual size of CD.

Here's in short:

Spelled out simply:


 21 minutes ==  94,500 sectors == 184.6MB CD-ROM == 212.0MB CD-DA
 63 minutes == 283,500 sectors == 553.7MB CD-ROM == 635.9MB CD-DA
 74 minutes == 333,000 sectors == 650.3MB CD-ROM == 746.9MB CD-DA
 80 minutes == 360,000 sectors == 703.1MB CD-ROM == 807.4MB CD-DA
 90 minutes == 405,000 sectors == 791.0MB CD-ROM == 908.4MB CD-DA
 99 minutes == 445,500 sectors == 870.1MB CD-ROM == 999.3MB CD-DA
What about DVDs then?

You can also use single quotes so that you don't have to escape certain characters on your output strings.

Any reason for making this a bash-specific script?

I could add DVD image creating too.
Anyway. I designed this script primary for myself. Later I decided to share this.

Bash is common and I don't know much perl or any other language suitable for this. Well... I could do this with php, but then there would be php depency. ;P
I guess hats meant it has some bash-specific syntax, so it might or might not work with ash, dash, lash, etc. other shells. Though bash is a standard component, so you're likely to find it on any linux system.
