Options

--snapshot filename

Create a snapshot image from the specified layers and save it to filename. The  snapshot is saved in PNG format.

--lang language

Set the language used by QGIS. Language is specified using the locale string that matches one of the translations supported by QGIS. For example, to use the German translation, specify --lang de

--project filename

Load the specified QGIS project file. The layers specified in the project file are loaded, the layers are symbolized, and the view extent is restored.

--extent xmin,ymin,xmax,ymax

Set initial map extent by passing coordinates of that rectangle.

--width width

Width of snapshot to emit

--height height

Height of snapshot to emit

Hide splash screen

--noplugins

Don't restore plugins on startup. Useful if some third-party plugins make QGIS crash during startup.

--optionspath path

Use the given QSettings path

--configpath path

Use the given path for all user configuration

--help

Display brief usage help.

file...

A list of one or more files to be loaded into QGIS at startup. Files must consist of a data format supported by QGIS and only disk-based formats can be loaded using this method. This includes shapefiles, MapInfo files, and most raster formats. Data stores that cannot be loaded in this way include PostGIS layers in a PostgreSQL database and GRASS vector/raster data.

Files

~/.config/QGIS/qgis.conf

QGIS preferences file. This file stores windows size/location, loaded plugins, user options, and other application settings.
