Show the HTML documentation for selected module


gmt docs [ -Q ] module-name [-option]

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


docs tells GMT to display the HTML version of a module’s documentation using the default browser. For the time being, only modern mode module names are displayed. That is, if user asks for gmt docs psxy she will see the (near-equivalent) plot documentation. Besides the modules names, the special forms cookbook, gallery, gmt.conf, api and tutorial are also accepted.

However, docs can also be used to open local files such as PDF or image files or even web link addresses.

Optional Arguments

This option means we are doing a “dry-run” and simply want the final URL to be printed to standard output. No browser command will take place. This is useful if you are working remotely on a server and do not wish to launch a GUI browser.

Optional Module Arguments

Where -option is the one-letter option of the module in question (e.g, -R). We then display the module documentation positioned at that specific option.
