Re: Mkoctfile help

[Henry F. Mollet]

Thanks. I'll change this to the way it hopwfully was:
dr-xr-xr-x   12 root  wheel      408 Aug 13 19:26 usr

Is the above correct or should it be
drwxr-xr-x 12 root admin, that's what I have on my old computer?
What is the difference between wheel and admin?

Am I correct, that when I now want to modify an octave .m file that I'll be
able to use the sudo command to copy it to my homedir and then modify it
there.
