Equivalent to shell command find . -name pattern in the ISO image.
\fB\-find\fR iso_rr_path [-name pattern]
A very restricted sunstitute for to shell command find in the ISO image.
It prints the paths of matchin file objects beginning with iso_rr_path.
.br
Optional -name pattern is not expanded but used for comparison with
the particular file names of the eventual directory tree underneath
iso_rr_path. If no -name pattern is given, then any file name matches.

Equivalent to shell command find . -name pattern on filesystem.
Like -find but operating on loacl filesystem and not on ISO image.
