When used to chain commands, as in "cmd1 || cmd2" it means run cmd1, if that fails run cmd2 (if the first command succeeds and returns true, the OR will alsays be true so there's no need to run cmd2). All is does here is exit the script if vobcopy or mkisofs return an error, because there'd be no point in continuing. > Also, how > can I run the script by typing /path/to/getdvd?

I keep my scripts in ~/bin, with the x bits set, and have ~/bin in $PATH, so I don't need to give the path to run them. -- Neil Bothwick SUBLIMINALsendmoneyTAGLINE
