checknr(1)              (BSD Compatibility Package)              checknr(1)


   NAME
         checknr - check nroff and troff input files; report possible errors

   SYNOPSIS
         /usr/ucb/checknr [ -fs ] [ -a .x1 .y1 .x2 .y2 ...  .xn .yn ]
              [ -c .x1 .x2 .x3 ...  .xn ] [ filename ...  ]

   DESCRIPTION
         The checknr command checks a list of nroff or troff input files for
         certain kinds of errors involving mismatched opening and closing
         delimiters and unknown commands.  If no files are specified, checknr
         checks the standard input.  Delimiters checked are:

               ⊕  Font changes using \fx ... \fP.

               ⊕  Size changes using \sx ... \s0.

               ⊕  Macros that come in open ... close forms, for example, the
                  .TS and .TE macros which must always come in pairs.

         checknr knows about the ms and me macro packages.

         checknr is intended to be used on documents that are prepared with
         checknr in mind.  It expects a certain document writing style for \f
         and \s commands, in that each \fx must be terminated with \fP and
         each \sx must be terminated with \s0.  While it will work to directly
         go into the next font or explicitly specify the original font or
         point size, and many existing documents actually do this, such a
         practice will produce complaints from checknr.  Since it is probably
         better to use the \fP and \s0 forms anyway, you should think of this
         as a contribution to your document preparation style.

         The following options are available:

         -f    Ignore \f font changes.

         -s    Ignore \s size changes.

         -a .x1 .y1...
               Add pairs of macros to the list.  The pairs of macros are
               assumed to be those (such as .DS and that should be checked for
               balance.  The -a option must be followed by groups of six
               characters, each group defining a pair of macros. The six
               characters are a period, the first macro name, another period,
               and the second macro name.  For example, to define a pair .BS
               and use -a.BS.ES

         -c .x1...
               Define commands which checknr would otherwise complain about as
               undefined.

         There is no way to define a one-character macro name using the -a
         option.
