NAME

       xmlcatalog - Command line tool to parse and manipulate XML or SGML catalog files.

SYNOPSIS

       xmlcatalog [--sgml | --shell | --create | --del VALUE(S) | [ --add TYPE ORIG REPLACE  | --add FILENAME] | --noout | --no-super-update |
		  [-v | --verbose]] {CATALOGFILE} {ENTITIES...}

DESCRIPTION

       xmlcatalog is a command line application allowing users to monitor and manipulate XML and SGML catalogs. It is included in libxml(3).

       Its functions can be invoked from a single command from the command line, or it can perform multiple functions in interactive mode. It can
       operate on both XML and SGML files.

OPTIONS

       xmlcatalog accepts the following options (in alphabetical order):

       --add TYPE ORIG REPLACE
	   Add an entry to CATALOGFILE.  TYPE indicates the type of entry. Possible types are: public, system, uri, rewriteSystem, rewriteURI,
	   delegatePublic, delegateSystem, delegateURI, nextCatalog.  ORIG is the original reference to be replaced, and REPLACE is the URI of the
	   replacement entity to be used. The --add option will not overwrite CATALOGFILE, outputting to stdout, unless --noout is used. The --add
	   will always take three parameters even if some of the XML catalog constructs will have only a single argument.

       --add FILENAME
	   If the --add option is used following the --sgml option, only a single argument, a FILENAME, is used. This is used to add the name of a
	   catalog file to an SGML supercatalog, a file that contains references to other included SGML catalog files.

       --create
	   Create a new XML catalog. Outputs to stdout, ignoring filename unless --noout is used, in which case it creates a new catalog file
	   filename.

       --del VALUE(S)
	   Remove entries from CATALOGFILE matching VALUE(S). The --del option will not overwrite CATALOGFILE, outputting to stdout, unless
	   --noout is used.

       --noout
	   Save output to the named file rather than outputting to stdout.

       --no-super-update
	   Do not update the SGML super catalog.

       --shell
	   Run a shell allowing interactive queries on catalog file CATALOGFILE. For the set of available commands see the section called "SHELL
	   COMMANDS".

       --sgml
	   Uses SGML super catalogs for --add and --del options.

       -v, --verbose
	   Output debugging information.

SHELL COMMANDS

       Invoking xmlcatalog with the --shell CATALOGFILE option opens a command line shell allowing interactive access to the catalog file
       identified by CATALOGFILE. Invoking the shell provides a command line prompt after which the following commands (described in alphabetical
       order) can be entered.

       add TYPE ORIG REPLACE
	   Add an entry to the catalog file.  TYPE indicates the type of entry. Possible types are: public, system, uri, rewriteSystem,
	   rewriteURI, delegatePublic, delegateSystem, delegateURI, nextCatalog.  ORIG is the original reference to be replaced, and REPLACE is
	   the URI of the replacement entity to be used. The --add option will not overwrite CATALOGFILE, outputting to stdout, unless --noout is
	   used. The --add will always take three parameters even if some of the XML catalog constructs will have only a single argument.

       debug
	   Print debugging statements showing the steps xmlcatalog is executing.

       del VALUE(S)
	   Remove the catalog entry corresponding to VALUE(S).

       dump
	   Print the current catalog.

       exit
	   Quit the shell.

       public PUBLIC-ID
	   Execute a Formal Public Identifier look-up of the catalog entry for PUBLIC-ID. The corresponding entry will be output to the command
	   line.

       quiet
	   Stop printing debugging statements.

       system SYSTEM-ID
	   Execute a Formal Public Identifier look-up of the catalog entry for SYSTEM-ID. The corresponding entry will be output to the command
	   line.

ENVIRONMENT

       XML_CATALOG_FILES
	   XML catalog behavior can be changed by redirecting queries to the user's own set of catalogs. This can be done by setting the
	   XML_CATALOG_FILES environment variable to a list of catalogs. An empty one should deactivate loading the default /etc/xml/catalog
	   catalog.

DIAGNOSTICS

       xmlcatalog return codes provide information that can be used when calling it from scripts.

       0
	   No error

       1
	   Failed to remove an entry from the catalog

       2
	   Failed to save to the catalog, check file permissions

       3
	   Failed to add an entry to the catalog

       4
	   Failed to look up an entry in the catalog
