NAME

       gmtset - Change individual GMT default parameters

SYNOPSIS

       gmtset  [  | [s|u] | defaultsfile ] [ -[BJRXxYycp]value ] PARAMETER1 [=] value1 PARAMETER2
       [=] value2 PARAMETER3 [=] value3

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

DESCRIPTION

       gmtset will adjust individual GMT defaults settings in the  current  directory's  gmt.conf
       file.  If  no  such  file  exists  one  will  be  created.  The  main purpose of gmtset is
       temporarily  to  change  certain  parameters  inside  a  shell  script,  e.g.,   set   the
       dots-per-inch  to  72,  run the script, and reset to 1200 dpi. Optionally, you can specify
       one or  more  temporary  changes  directly  on  any  GMT  command  line  with  the  syntax
       --PARAMETER=VALUE; such changes are only in effect for that command and do not permanently
       change the default settings on disk.

REQUIRED ARGUMENTS

       PARAMETER value
              Provide one or several pairs of  parameter/value  combinations  that  you  want  to
              modify.  For  a complete listing of available parameters and their meaning, see the
              gmt.conf man page.

OPTIONAL ARGUMENTS

       -C     Convert a .gmtdefaults4 file created by GMT4 to a gmt.conf file used by  GMT5.  The
              original file is retained.

       -D[s|u]
              Modify the GMT defaults based on the system settings. Append u for US defaults or s
              for SI defaults. [-D alone gives the version selected at compile time]

       -Gdefaultsfile
              Name of specific gmt.conf file to read and modify [Default looks first  in  current
              directory,  then  in  your home directory, then in ~/.gmt and finally in the system
              defaults].

       -[BJRXxYycp]value
              Set the expansion of any of these shorthand options.

       -^ 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.

       --version
              Print GMT version and exit.

       --show-datadir
              Print full path to GMT share directory and exit.

EXAMPLES

       To change annotation font to 12-point Helvetica, select grid-crosses of size 0.1 inch, and
       set annotation offset to 0.2 cm:

              gmt set FONT_ANNOT_PRIMARY 12p,Helvetica \
                      MAP_GRID_CROSS_SIZE_PRIMARY 0.1i MAP_ANNOT_OFFSET_PRIMARY 0.2c
