gmtdefaults1gmt
List current gmt default parameters
Usage
gmtdefaults [-D
[{u | s}]]
Overview
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
ufor US defaults orsfor SI defaults. [-Dalone gives the version selected at compile time; If-Dis 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.confYou 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.
