# sgmlcheck(1)

check the syntax of an LinuxDoc DTD sgml source file

## NAME

sgmlcheck - check the syntax of an LinuxDoc DTD sgml source file

## SYNOPSIS

**sgmlcheck** *file*\[.sgml\]

## DESCRIPTION

**sgmlcheck** is an old and obsoleted form of the SGML source checker command of LinuxDoc-Tools (its name may be misleading, as it is not a tool for any SGML DTD, only supports the SGML LinuxDoc DTD). It is recommended to switch the new form **linuxdoc -B check** now. It runs an SGML parse on the specified document source. Any errors are reported to standard output. No formatted version of the source is produced.

Note that **sgmlcheck** preprocesses the LinuxDoc DTD SGML source, doing the conditionalization described by any \<#if\>\</#if\> and \<#unless\>\</#unless\> tags. Document sources containing these tags will confuse a standalone SGML parser.

## OPTIONS

None.  The generic options described in [**linuxdoc**(1)](/linuxdoc/1.md) are accepted, but have no effect (except for -D).

## FILES

Many files and executables in /usr/share/linuxdoc-tools and /usr/bin are used.

## BUGS

None known.
