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. |
