checknr(1BSD) (BSD System Compatibility) checknr(1BSD)
NAME
checknr - (BSD) 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] [file . . .]
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 .BE, use -a.BS.BE
-c.x1 . . .
Define commands which checknr would otherwise complain
about as undefined.

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