Sorry, user mwadmin is not allowed to execute '/bin/mkdir -p /usr/test' as root.

Even if you set that up correctly, on your system, according to the diagnostic message, mkdir isn't under the /usr hierarchy.

More importantly, as I said, there are multiple errors in your attempt at a sudoers entry.

Did you edit sudoers using visudo? I suspect not, because it would have detected a syntax error (it should be an equals sign after the host specification, not a colon).

Aside from that, there are other non-syntactic, logical errors. Command specifications are comma-delimited. Your command specification will be treated as one long spec, not three. Only files in /www/ will match and the other two patterns are used to restrict the command's arguments.

Even if you delimited the command specifications correctly, the wildcards would not behave as you expect. As with shell pattern matching (aka globbing), the * will not match /. This means that /usr/* only matches files in /usr. It will match /usr/bin/, the directory itself, but not any of the executables of interest in /usr/bin and /usr/sbin.

Wildcards are unnecessary to match all files in a directory. The command specification can list a directory directly and that will be interpreted as matching any executable within it.

You really should spend an evening with the sudo, sudoers, and visudo documentation and inform yourself.

Alister

EMPTY-PAGE(1)							 ExactImage Manual						     EMPTY-PAGE(1)

NAME

       empty-page - empty page detector of the ExactImage toolkit

SYNOPSIS

       empty-page [option...] {-i | --input} input-file

       empty-page {-h | --help}

DESCRIPTION

       ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
       depths natively, resulting in low memory and computational requirements.

       empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
       be removed from the image processing stream.

OPTIONS

       -i file, --input file
	   Read image from the specified file.

       -m n, --margin n
	   Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.

       -p x, --percentage x
	   Set fraction of permissible dark pixels. The default is 0.05 (5%).

       -h, --help
	   Display help text and exit.

EXAMPLES

	   $ empty-page -i test.tif
	   The image has 75461 dark pixels from a total of 1060992 (7.11231%).
	   non-empty

EXIT STATUS

       The exit status is 0 if the image is mostly white, 1 otherwise.
