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.
