## NAME

checknr - Checks nroff files

## SYNOPSIS

checknr [-fs] [-a.x1.y1.x2.y2 ... .xn.yn] [-c.x1.x2.x3 ... .xn] [file...]

The checknr command checks a list of nroff input files for certain kinds of errors involving mismatched opening and closing delimiters and unknown commands.

## OPTIONS

Adds pairs of macros to the list. This 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 .ES, use -a.BS.ES. (You cannot use the -a option to define a 1-character macro name.) Defines otherwise undefined commands. Causes checknr to ignore \f font changes. Causes checknr to ignore \s size changes.

## DESCRIPTION

If no files are specified, checknr checks the standard input. Delimiters checked are as follows: 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.

The checknr command can handle both the ms and me macro packages.

The checknr command 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 terminated with \fP and each \sx must be terminated with \s0. While it will work to go directly into the next font or explicitly specify the original font or point size, and many existing documents actually do this, such a practice produces error messages from checknr.

The checknr command does not recognize certain reasonable constructs, such as conditionals.
