NAME

       xrdb - X server resource database utility

SYNOPSIS

       xrdb [-option ...] [filename]

DESCRIPTION

       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 standard 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:

       SERVERHOST=hostname
               the hostname portion of the display to which you are connected.

       SRVR_name
               the  SERVERHOST hostname string turned into a legal identifier.
               For        example,        "my-dpy.lcs.mit.edu"         becomes
               SRVR_my_dpy_lcs_mit_edu.

       HOST=hostname
               the same as SERVERHOST.

       DISPLAY_NUM=num
               the number of the display on the server host.

       CLIENTHOST=hostname
               the name of the host on which xrdb is running.

       CLNT_name
               the  CLIENTHOST hostname string turned into a legal identifier.
               For example, "expo.lcs.mit.edu" becomes CLNT_expo_lcs_mit_edu.

       RELEASE=num
               the vendor release number for the server.   The  interpretation
               of this number will vary depending on VENDOR.

       REVISION=num
               the   X   protocol  minor  version  supported  by  this  server
               (currently 0).

       VERSION=num
               the X protocol major version supported by this  server  (should
               always be 11).

       VENDOR="vendor"
               a string literal specifying the vendor of the server.

       VNDR_name
               the  VENDOR  name  string  turned into a legal identifier.  For
               example, "MIT X Consortium" becomes VNDR_MIT_X_Consortium.

       EXT_name
               A symbol is defined for each protocol  extension  supported  by
               the  server.  Each extension string name is turned into a legal
               identifier.  For example, "X3D-PEX" becomes EXT_X3D_PEX.

       NUM_SCREENS=num
               the total number of screens.

       SCREEN_NUM=num
               the number of the current screen (from zero).

       BITS_PER_RGB=num
               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 to PLANES.

       CLASS=visualclass
               one   of   StaticGray,   GrayScale,  StaticColor,  PseudoColor,
               TrueColor, DirectColor.  This is the visual class of  the  root
               window.

       CLASS_visualclass=visualid
               the  visual  class  of the root window in a form you can #ifdef
               on.  The value is the numeric id of the visual.

       COLOR   defined only if  CLASS  is  one  of  StaticColor,  PseudoColor,
               TrueColor, or DirectColor.

       CLASS_visualclass_depth=num
               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.)

       HEIGHT=num
               the height of the root window in pixels.

       WIDTH=num
               the width of the root window in pixels.

       PLANES=num
               the number of bit planes (the depth) of the root window.

       X_RESOLUTION=num
               the x resolution of the screen in pixels per meter.

       Y_RESOLUTION=num
               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.

OPTIONS

       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.

       -display display
               This option specifies the X server to be used;  see  X(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 -global option.

       -all    This option indicates that operation should be performed 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 RESOURCE_MANAGER property.

       -screen This  option  indicates  that  the  operation  should  only  be
               performed  on  the  SCREEN_RESOURCES  property  of  the default
               screen of the display.

       -screens
               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.

       -cpp filename
               This  option  specifies  the  pathname  of  the  C preprocessor
               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 used.

       -nocpp  This option indicates that xrdb should not run the  input  file
               through a preprocessor before loading it into properties.

       -symbols
               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  commands  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
               properties 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.

       -override
               This option indicates  that  the  input  should  be  added  to,
               instead  of  replacing,  the  current contents of the specified
               properties.  New entries override previous entries.

       -merge  This option indicates that  the  input  should  be  merged  and
               lexicographically   sorted  with,  instead  of  replacing,  the
               current contents of the specified properties.

       -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  should  never  be
               necessary  under  normal conditions, since xdm and xinit always
               act as the first client.

       -edit filename
               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, preserving any comments or preprocessor lines.

       -backup string
               This option specifies a suffix to be appended to  the  filename
               used with -edit to generate a backup file.

       -Dname[=value]
               This  option  is passed through to the preprocessor and is used
               to define symbols for use with conditionals such as #ifdef.

       -Uname  This option is passed through to the preprocessor and  is  used
               to remove any definitions of this symbol.

       -Idirectory
               This  option  is passed through to the preprocessor and is used
               to specify a directory to search for files that are  referenced
               with #include.

BUGS

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