xrdb - X server resource database utility
xrdb [-option ...] [filename]
Xrdb is used to get or set the contents of the
RESOURCE_MANAGER property on the root window of screen 0, or
the SCREEN_RESOURCES property on the root window of any or
all screens, or everything combined. You would normally run
this program from your X startup file.
Most X clients use the RESOURCE_MANAGER and SCREEN_RESOURCES
properties to get user preferences about color, fonts, and
so on for applications. Having this information in the
server (where it is available to all clients) instead of on
disk, solves the problem in previous versions of X that
required you to maintain defaults files on every machine
that you might use. It also allows for dynamic changing of
defaults without editing files.
The RESOURCE_MANAGER property is used for resources that
apply to all screens of the display. The SCREEN_RESOURCES
property on each screen specifies additional (or overriding)
resources to be used for that screen. (When there is only
one screen, SCREEN_RESOURCES is normally not used, all
resources are just placed in the RESOURCE_MANAGER property.)
The file specified by filename (or the contents from stan-
dard input if - or no filename is given) is optionally
passed through the C preprocessor with the following symbols
defined, based on the capabilities of the server being used:
the hostname portion of the display to which you are
the SERVERHOST hostname string turned into a legal
identifier. For example, "my-dpy.lcs.mit.edu"
the same as SERVERHOST.
the number of the display on the server host.
the name of the host on which xrdb is running.
the CLIENTHOST hostname string turned into a legal
identifier. For example, "expo.lcs.mit.edu" becomes
the vendor release number for the server. The
interpretation of this number will vary depending on
the X protocol minor version supported by this
server (currently 0).
the X protocol major version supported by this
server (should always be 11).
a string literal specifying the vendor of the
the VENDOR name string turned into a legal identif-
ier. For example, "MIT X Consortium" becomes
A symbol is defined for each protocol extension sup-
ported by the server. Each extension string name is
turned into a legal identifier. For example, "X3D-
PEX" becomes EXT_X3D_PEX.
the total number of screens.
the number of the current screen (from zero).
the number of significant bits in an RGB color
specification. This is the log base 2 of the number
of distinct shades of each primary that the hardware
can generate. Note that it usually is not related
one of StaticGray, GrayScale, StaticColor, Pseu-
doColor, TrueColor, DirectColor. This is the visual
class of the root window.
the visual class of the root window in a form you
can #ifdef on. The value is the numeric id of the
COLOR defined only if CLASS is one of StaticColor, Pseu-
doColor, TrueColor, or DirectColor.
A symbol is defined for each visual supported for
the screen. The symbol includes the class of the
visual and its depth; the value is the numeric id of
the visual. (If more than one visual has the same
class and depth, the numeric id of the first one
reported by the server is used.)
the height of the root window in pixels.
the width of the root window in pixels.
the number of bit planes (the depth) of the root
the x resolution of the screen in pixels per meter.
the y resolution of the screen in pixels per meter.
SRVR_name, CLNT_name, VNDR_name, and EXT_name identifiers
are formed by changing all characters other than letters and
digits into underscores (_).
Lines that begin with an exclamation mark (!) are ignored
and may be used as comments.
Note that since xrdb can read from standard input, it can be
used to the change the contents of properties directly from
a terminal or from a shell script.
xrdb program accepts the following options:
-help This option (or any unsupported option) will cause a
brief description of the allowable options and
parameters to be printed.
This option specifies the X server to be used; see
X11(7). It also specifies the screen to use for the
-screen option, and it specifies the screen from
which preprocessor symbols are derived for the -glo-
-all This option indicates that operation should be per-
formed on the screen-independent resource property
(RESOURCE_MANAGER), as well as the screen-specific
property (SCREEN_RESOURCES) on every screen of the
display. For example, when used in conjunction with
-query, the contents of all properties are output.
For -load, -override and -merge, the input file is
processed once for each screen. The resources which
occur in common in the output for every screen are
collected, and these are applied as the screen-
independent resources. The remaining resources are
applied for each individual per-screen property.
This the default mode of operation.
-global This option indicates that the operation should only
be performed on the screen-independent
-screen This option indicates that the operation should only
be performed on the SCREEN_RESOURCES property of the
default screen of the display.
This option indicates that the operation should be
performed on the SCREEN_RESOURCES property of each
screen of the display. For -load, -override and
-merge, the input file is processed for each screen.
-n This option indicates that changes to the specified
properties (when used with -load, -override or
-merge) or to the resource file (when used with
-edit) should be shown on the standard output, but
should not be performed.
-quiet This option indicates that warning about duplicate
entries should not be displayed.
This option specifies the pathname of the C prepro-
cessor program to be used. Although xrdb was
designed to use CPP, any program that acts as a
filter and accepts the -D, -I, and -U options may be
-nocpp This option indicates that xrdb should not run the
input file through a preprocessor before loading it
This option indicates that the symbols that are
defined for the preprocessor should be printed onto
the standard output.
-query This option indicates that the current contents of
the specified properties should be printed onto the
standard output. Note that since preprocessor com-
mands in the input resource file are part of the
input file, not part of the property, they won't
appear in the output from this option. The -edit
option can be used to merge the contents of proper-
ties back into the input resource file without
damaging preprocessor commands.
-load This option indicates that the input should be
loaded as the new value of the specified properties,
replacing whatever was there (i.e. the old contents
are removed). This is the default action.
This option indicates that the input should be added
to, instead of replacing, the current contents of
the specified properties. New entries override pre-
-merge This option indicates that the input should be
merged and lexicographically sorted with, instead of
replacing, the current contents of the specified
-remove This option indicates that the specified properties
should be removed from the server.
-retain This option indicates that the server should be
instructed not to reset if xrdb is the first client.
This never be necessary under normal conditions,
since xdm and xinit always act as the first client.
This option indicates that the contents of the
specified properties should be edited into the given
file, replacing any values already listed there.
This allows you to put changes that you have made to
your defaults back into your resource file, preserv-
ing any comments or preprocessor lines.
This option specifies a suffix to be appended to the
filename used with -edit to generate a backup file.
This option is passed through to the preprocessor
and is used to define symbols for use with condi-
tionals such as
-Uname This option is passed through to the preprocessor
and is used to remove any definitions of this sym-
This option is passed through to the preprocessor
and is used to specify a directory to search for
files that are referenced with #include.

The default for no arguments should be to query, not to
overwrite, so that it is consistent with other programs.
