gmtset − To change individual GMT default parameters
gmtset [ −Gdefaultsfile ] PARAMETER1 [=] value1 PARAMETER2 [=] value2 PARAMETER3 [=] value3 ...
gmtset
will adjust individual GMT defaults settings in the
current directory’s .gmtdefaults4 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 600,
run the script, and reset to 300 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.
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 gmtdefaults man page.
