CHECKNR(1) General Commands Manual CHECKNR(1)
checknr - check nroff and troff input files; report possible errors
checknr [ -fs ] [ -a .x1 .y1 .x2 .y2 ... .xn .yn ]
[ -c .x1 .x2 .x3 ... .xn ] [ filename ... ]
This command is available with the Text software installation option.
Refer to for information on how to install optional software.
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. Delimiters checked are:
o Font changes using \fx ... \fP.
o Size changes using \sx ... \s0.
o 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.
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 contri-
bution to your document preparation style.
-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 .DE) 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 char-
acters 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'
Define commands which checknr would otherwise complain about as
eqn(1), nroff(1), troff(1), me(7), ms(7)
There is no way to define a one-character macro name using the -a
