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  exam-
        ple,  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 ter-
minated 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.

NOTES

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