### update-xmlcatalog --help

## DESCRIPTION
       **update-xmlcatalog** add entries to and removes entries from the root XML catalog file, a
       package XML catalog file or a local XML catalog file.

## OPTIONS
### --add
           Adds the entry to the root XML catalog file, a package XML catalog file or a local XML
           catalog file.  If the XML catalog file does not exist yet, it is automatically created.

### --del
           Deletes the entry from the root XML catalog file, the package XML catalog file or the
           local XML catalog file.  A resulting empty XML catalog is not automatically deleted from
           the filesystem.

       **--file** _file_
           Indicates a local filename.

       **--id** _id_
           Indicates the XML catalog file entry identifier.

       **--local** _local_
           Indicates a local XML catalog file.

       **--package** _package_
           Indicates a package XML catalog file.

### --root
           Indicates the root XML catalog file.

       **--type** _type_
           Indicates the XML catalog file entry type (public, system, uri).

### --help
           Displays the usage information.

### --verbose
           Optional switch to make a verbose output.

### --sort
           Optional switch to sort the manipulated catalog content.

           Tip: To sort a catalog without adding or removing an item, just add an already existing
           item to the catalog.

## NOTES
       **update-xmlcatalog** is the de-facto standard tool to be used to maintain XML catalog files on a
       Debian system, similar to that [**update-catalog**(8)](https://www.chedong.com/phpMan.php/man/update-catalog/8/markdown) is the standard tool to be used to main SGML
       catalog files on a Debian system.  A Debian XML Policy document to this effect is currently
       under development.

       **update-xmlcatalog** and [**xmlcatalog**(1)](https://www.chedong.com/phpMan.php/man/xmlcatalog/1/markdown) are incompatible.  The former has an internal database of
       all the entries in all the XML catalog files it maintains and regenerates the indicated XML
       catalog file completely from scratch upon an update.  The latter updates the indicated XML
       catalog file directly.  This means that any change made to an XML catalog file using
       [**xmlcatalog**(1)](https://www.chedong.com/phpMan.php/man/xmlcatalog/1/markdown) is overwritten the next time that XML catalog file is updated using **update-**
       **xmlcatalog**.
