My error in mkisofs command to make a command line iso

Hello,

I am attempting to recreate an iso from a set of files. At this point I seem to be stuck on the creation process. I have reviewed man mkisofs, which returns genisofs. Below is the actual command, and what each piece of information seems to provide

mike@presario:~$ sudo mkisofs
-V "LAMPPIX" -r -J -b isolinux/isolinux.bin -c /home/mike/master/isolinux/boot.cat -boot-load-size 4 -boot-info-table -o /home/mike/lamppix-mini-own.iso

I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage: Missing pathspec.
Usage: genisoimage [options] -o file directory ...

sudo mkisofs -V "LAMPPIX" Sets the Volume Name
-r Generate Rock Ridge Directory information
-J Specifies to use the Joliet directory info
-b isolinux/isolinux.bin Set El Torito boot image name
-c /home/mike/master/isolinux/boot.cat This is the only file that is named boot.cat in a original iso files
-boot-load-size 4 Likely a cmd for making it bootable ?
-boot-info-table Likely a cmd for making it bootable ?
-o /home/mike/lamppix-mini-own.iso Set a full path to where to create the final iso

All four of the original folders are contained in /home/mike/master. Some other postingstate the -o option as relative ( relative to what I'm not clear, others state when in doubt use the full path). Also the working directory is set to /home/mike when this command is run.

Can anyone explain my error with the -o option??

Thank you,

There is an excellent example here (edit iso)
http://www.asylumnation.com/blogs/am...post-2775.html

Code:

#!/bin/bash
 # make the new iso and put in root.
 mkisofs -o /new.iso -b isolinux/isolinux.bin \
 -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
 -boot-info-table -J -R -V disks .
 #

Good Luck !
P.S.: The -o option should be in the beginning of the
command instead of being the last part ??
The "example" works fine, have used it several times.
