7       catalog files.

SYNOPSIS

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

DESCRIPTION

16       xmlcatalog is a command line application allowing users to monitor and
17       manipulate XML and SGML catalogs. It is included in libxml(3).
18
19       Its functions can be invoked from a single command from the command
20       line, or it can perform multiple functions in interactive mode. It can
21       operate on both XML and SGML files.
22

OPTIONS

24       xmlcatalog accepts the following options (in alphabetical order):
25
26       --add TYPE ORIG REPLACE
27           Add an entry to CATALOGFILE.  TYPE indicates the type of entry.
28           Possible types are: public, system, uri, rewriteSystem, rewriteURI,
29           delegatePublic, delegateSystem, delegateURI, nextCatalog.  ORIG is
30           the original reference to be replaced, and REPLACE is the URI of
31           the replacement entity to be used. The --add option will not
32           overwrite CATALOGFILE, outputting to stdout, unless --noout is
33           used. The --add will always take three parameters even if some of
34           the XML catalog constructs will have only a single argument.
35
36       --add FILENAME
37           If the --add option is used following the --sgml option, only a
38           single argument, a FILENAME, is used. This is used to add the name
39           of a catalog file to an SGML supercatalog, a file that contains
40           references to other included SGML catalog files.
41
42       --create
43           Create a new XML catalog. Outputs to stdout, ignoring filename
44           unless --noout is used, in which case it creates a new catalog file
45           filename.
46
47       --del VALUE(S)
48           Remove entries from CATALOGFILE matching VALUE(S). The --del option
49           will not overwrite CATALOGFILE, outputting to stdout, unless
50           --noout is used.
51
52       --noout
53           Save output to the named file rather than outputting to stdout.
54
55       --no-super-update
56           Do not update the SGML super catalog.
57
58       --shell
59           Run a shell allowing interactive queries on catalog file
60           CATALOGFILE. For the set of available commands see the section
61           called “SHELL COMMANDS”.
62
63       --sgml
64           Uses SGML super catalogs for --add and --del options.
65
66       -v, --verbose
67           Output debugging information.
68
69       Invoking xmlcatalog non-interactively without a designated action
70       (imposed with options like --add) will result in a lookup of the
71       catalog entry for ENTITIES in the catalog denoted with CATALOGFILE. The
72       corresponding entries will be output to the command line. This mode of
73       operation, together with --shell mode and non-modifying (i.e. without
74       --noout) direct actions, allows for a special shortcut of the void
75       CATALOGFILE specification (possibly expressed as "" in the shell
76       environment) appointing the default system catalog. That simplifies the
77       handling when its exact location is irrelevant but the respective
78       built-in still needs to be consulted.
79

SHELL COMMANDS

81       Invoking xmlcatalog with the --shell CATALOGFILE option opens a command
82       line shell allowing interactive access to the catalog file identified
83       by CATALOGFILE. Invoking the shell provides a command line prompt after
84       which the following commands (described in alphabetical order) can be
85       entered.
86
87       add TYPE ORIG REPLACE
88           Add an entry to the catalog file.  TYPE indicates the type of
89           entry. Possible types are: public, system, uri, rewriteSystem,
90           rewriteURI, delegatePublic, delegateSystem, delegateURI,
91           nextCatalog.  ORIG is the original reference to be replaced, and
92           REPLACE is the URI of the replacement entity to be used. The --add
93           option will not overwrite CATALOGFILE, outputting to stdout, unless
94           --noout is used. The --add will always take three parameters even
95           if some of the XML catalog constructs will have only a single
96           argument.
97
98       debug
99           Print debugging statements showing the steps xmlcatalog is
100           executing.
101
102       del VALUE(S)
103           Remove the catalog entry corresponding to VALUE(S).
104
105       dump
106           Print the current catalog.
107
108       exit
109           Quit the shell.
110
111       public PUBLIC-ID
112           Execute a Formal Public Identifier lookup of the catalog entry for
113           PUBLIC-ID. The corresponding entry will be output to the command
114           line.
115
116       quiet
117           Stop printing debugging statements.
118
119       system SYSTEM-ID
120           Execute a Formal Public Identifier lookup of the catalog entry for
121           SYSTEM-ID. The corresponding entry will be output to the command
122           line.
123

ENVIRONMENT

125       XML_CATALOG_FILES
126           XML catalog behavior can be changed by redirecting queries to the
127           user's own set of catalogs. This can be done by setting the
128           XML_CATALOG_FILES environment variable to a space-separated list of
129           catalogs. Use percent-encoding to escape spaces or other
130           characters. An empty variable should deactivate loading the default
131           /etc/xml/catalog catalog.
132
