CHECKNR(1) General Commands Manual CHECKNR(1)
checknr - check nroff/troff files
checknr [ -s ] [ -f ] [ -a.x1.y1.x2.y2. ... .xn.yn ] [ -c.x1.x2.x3 ...
.xn ] [ file ... ]
Checknr checks a list of nroff(1) or troff(1) input files for certain
kinds of errors involving mismatched opening and closing delimiters and
unknown commands. If no files are specified, checknr checks the stan‐
dard input. Delimeters checked are:
(1) Font changes using \fx ... \fP.
(2) Size changes using \sx ... \s0.
(3) 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(7) and me(7) macro packages.
Additional pairs of macros can be added to the list using the -a
option. This 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 .ES, use -a.BS.ES
The -c option defines commands which would otherwise be complained
about as undefined.
The -f option requests checknr to ignore \f font changes.
The -s option requests checknr to ignore \s size changes.
Checknr is intended to be used on documents that are prepared with
checknr in mind, much the same as lint. It expects a certain document
writing style for \f and \s commands, in that each \fx must be termi‐
nated 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 origi‐
nal 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.

Various complaints about the syntax of commands.
There is no way to define a 1 character macro name using -a.
