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

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
