Whats your definition of irony?
Mine is when the intended outcome or meaning juxtaposes significantly enough from the actual outcome or meaning for me to seek out the unix.com forums, become a member, post a problem, read a WORKAROUND solution, then be told the WORKAROUND is intended somehow as a subtle misinterpretation of the man page (missed that the lines must be ADJACENT) for uniq to do its -c switch as documented in the manpage:

-c Precede each output line with the count of the number of times the line occurred in the input, fol-
lowed by a single space.


Imagine if I implemented "sort" and said "applies only to letters I R O N and Y" (but buried that subtly with one word in a man page)

At least the uniq man page should clarify this with a note and a switch to presort (on the penalty of performance) to deliver the EXPECTED -c results?

I would like to see the uniq source code - is there a reference?

thanks

GLGETPROGRAMPIPELINE(3G)					   OpenGL Manual					  GLGETPROGRAMPIPELINE(3G)

NAME

       glGetProgramPipeline - retrieve properties of a program pipeline object

C SPECIFICATION

       void glGetProgramPipelineiv(GLuint pipeline, GLenum pname, GLint *params);

PARAMETERS

       pipeline
	   Specifies the name of a program pipeline object whose parameter retrieve.

       pname
	   Specifies the name of the parameter to retrieve.

       params
	   Specifies the address of a variable into which will be written the value or values of pname for pipeline.

DESCRIPTION

       glGetProgramPipelineiv retrieves the value of a property of the program pipeline object pipeline.  pname specifies the name of the
       parameter whose value to retrieve. The value of the parameter is written to the variable whose address is given by params.

       If pname is GL_ACTIVE_PROGRAM, the name of the active program object of the program pipeline object is returned in params.

       If pname is GL_VERTEX_SHADER, the name of the current program object for the vertex shader type of the program pipeline object is returned
       in params.

       If pname is GL_TESS_CONTROL_SHADER, the name of the current program object for the tessellation control shader type of the program pipeline
       object is returned in params.

       If pname is GL_TESS_EVALUATION_SHADER, the name of the current program object for the tessellation evaluation shader type of the program
       pipeline object is returned in params.

       If pname is GL_GEOMETRY_SHADER, the name of the current program object for the geometry shader type of the program pipeline object is
       returned in params.

       If pname is GL_FRAGMENT_SHADER, the name of the current program object for the fragment shader type of the program pipeline object is
       returned in params.

       If pname is GL_INFO_LOG_LENGTH, the length of the info log, including the null terminator, is returned in params. If there is no info log,
       zero is returned.

ERRORS

       GL_INVALID_OPERATION is generated if pipeline is not zero or a name previously returned from a call to glGenProgramPipelines() or if such a
       name has been deleted by a call to glDeleteProgramPipelines().

       GL_INVALID_ENUM is generated if pname is not one of the accepted values.
