I think that the original code is faulty, therefore I deduced the probable function from the output messages.
We could do with some input from the O/P .


Interesting point in the Open Group posting about "test" with an "and" clause when the first parameter is "!" and the second parameter is blank. Not come across the problem myself but the point is valid.

My point about [[ was badly worded. It was about removing the distinction between [[ and [ with view to removing [[ completely. Similarly "test" as an external commmand was to be depreciated.

Interestingly the current proposal has backed down on this one.
See "rationale" in this link:
test
This wasn't the only place I have read about [[ by far. I take a mild interest because of historic trouble with [[ and ]] being external commands and some painful diagnostics of badly written Conditional Expressions.


If a unix comes out with a Shell which is too diverse I will just recommend that we do not purchase.

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.
