gmtdefaults(1gmt)

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 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 use just -).

   -+ 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 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.
