update-catalog – create or update entry in SGML catalog file

update-catalog [options] –remove centralized_catalog ordinary_catalog

update-catalog [options] –update-super


update-catalog inserts, updates or removes entries in the SGML central‐
ized catalogs located in /etc/sgml. To change the SGML super catalog
located in /etc/sgml/catalog modify the directory contents of /etc/sgml
to contain new files or symbolic links having a .cat extension or
remove (or move) existing centralized catalogs and regenerate the super
catalog using the –update-super option. See section SUPER CATALOG for
details on the generation process.

/etc/sgml directory. See section SUPER CATALOG for details on
the super catalog generation.

The super-catalog located in /etc/sgml/catalog cannot be directly modi‐
fied. It is generated by the update-catalog –update-super command.
The generation considers files in the /etc/sgml directory that have a
.cat extension. For instance files ending in .old or .disabled are not
considered. Before adding a catalog to the super catalog it is parsed
and verified in order to not corrupt the super catalog. All referenced
catalogs are verified to actually exist. If the check fails, a message
is printed and the complete catalog is ignored. This check ensures
that a catalog from a package, which is removed but not purged, is
removed from the super catalog.
