Name
xmlcatalog — Command line tool to parse and manipulate XML or
      SGML catalog files.
Synopsis
xmlcatalog  [--shell | --create | --add type
	  orig replace | --del values | --noout | --verbose] [catalogfile] [entities]
Introduction
      xmlcatalog is a command line application
      allowing users to monitor and manipulate XML and
      SGML catalogs. It is included in
      libxml2.
    
      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.
    
Command Line Options
- --shell filename
- 
	    Run a shell
	    allowing interactive queries on catalog file
	    filename.
	  
- --create filename
- 
	    Create a new
	    XML catalog. Outputs to stdout, ignoring
	    filename unless --noout is
	    used, in which case it creates a new catalog file
	    filename.
	  
- --add 'type' 'orig' 'replace' filename
- 
	    Add an entry to catalog file
	    filename. type indicates
	    the type of entry. Possible types are 'public', 'system', 'rewriteSystem',
	    'delegatePublic' and 'delegateSystem'. '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
	    filename, outputing 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.
	   - 
	    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.
	   
- --del 'values' filename
- 
	    Remove entries from the catalog file
	    filename matching
	    'values'. The --del option
	    will not overwrite filename, outputing to
	    stdout, unless --noout is used.
	  
- --noout
- 
	    Save output to the named file rather than
	    outputing to stdout.
	  
- -v or --verbose
- 
	    output debugging
	    information.
	  
Shell Commands
Invoking xmlcatalog with the
      --shell filename option opens
    a command line shell allowing interactive access to the catalog file
      identified by filename. Invoking the shell
    provides a command line prompt after which commands can be entered.
    
- public 'PublicID'
- 
	    Execute a
	    public identifier lookup of the catalog entry for
	    'PublicID'. The corresponding entry will be
	    output to the command line.
	  
- system 'SystemID'
- 
	    Execute a
	    public identifier lookup of the catalog entry for
	    'SystemID'. The corresponding entry will be
	    output to the command line.
	  
- add  'type' 'orig' 'replace'
- 
	    Add an entry to the catalog
	    file. type indicates the type of
	    entry. Possible types are 'public', 'system', 'rewriteSystem',
	    'delegatePublic' and 'delegateSystem'. 'orig'
	    is the original reference to  be replaced, and
	    'replace' is the URI of the
	    replacement entity to be used.
	  
- del 'values'
- 
	    Remove the
	    catalog entry corresponding to 'values'.
	  
- dump
- 
	    Print the current catalog.
	  
- debug
- 
	    Print debugging statements showing the steps
	    xmlcatalog is executing.
	  
- quiet
- 
	    Stop printing debugging statements.
	  
- exit
- 
	    Quit the shell.
