NAME
       gmtdefaults - List current GMT default parameters


SYNOPSIS
       gmtdefaults [  -D[u|s] ]

       Note: No space is allowed between the option flag and the associated arguments.


DESCRIPTION
       gmtdefaults lists all the GMT parameter defaults if the option -D is used. There are three ways to change
       some of the settings: (1) Use the command gmtset, (2) use any text editor to edit the  file  gmt.conf  in
       your  home,  ~/.gmt or current directory (if you do not have this file, run gmtset -D to get one with the
       system default settings), or (3) override any parameter  by  specifying  one  or  more  --PARAMETER=VALUE
       statements on the command line of any GMT command (PARAMETER and VALUE are any combination listed below).
       The first two options are permanent changes until explicitly changed  back,  while  the  last  option  is
       ephemeral  and only applies to the single GMT command that received the override. GMT can provide default
       values in US or SI units. This choice is determined at compile time.


REQUIRED ARGUMENTS
       None.


OPTIONAL ARGUMENTS
       -D     Print the system GMT defaults to standard output. Append u for US defaults or s for  SI  defaults.
              [-D  alone  gives  the  version  selected  at compile time; If -D is omitted, the user’s currently
              active defaults are printed.]

       -^ or just -
              Print a short message about the syntax of the command, then exits (NOTE: on Windows just use -).

       -+ or just +
              Print an extensive usage (help) message, including the explanation of any  module-specific  option
              (but not the GMT common options), then exits.

       -? or no arguments
              Print a complete usage (help) message, including the explanation of all options, then exits.

       Your  currently active defaults come from the gmt.conf file in the current working directory, if present;
       else from the gmt.conf file in your home directory, if present; else from  the  file  ~/.gmt/gmt.conf  if
       present; else from the system defaults set at the time GMT was compiled.


GMT PARAMETERS
       Read the gmt.conf man page for a full list of the parameters that are user-definable in GMT.


EXAMPLES
       To get a copy of the GMT parameter defaults in your home directory, run

              gmt defaults -D > ~/gmt.conf

       You may now change the settings by editing this file using a text editor of your choice, or use gmtset to
       change specified parameters on the command line.


BUGS
       If you have typographical errors in your gmt.conf file(s), a warning message will be issued, and the  GMT
       defaults for the affected parameters will be used.
