Welcome! There is a lot of help on the web and a wealth of expertise available on the mailing lists and via IRC.

Tips for ArcGIS users
GRASS GIS for ArcGIS users
Watershed Analysis with GRASS (in case you know the ESRI way)
Whatever-GIS-Software to GRASS command translation table and discussion (obsolete)
GRASS 4 and 5 users: GRASS Module Porting List (check here if you don't find a certain command in GRASS 6)
GRASS 7 users: List of new features in GRASS 7 (new names, options, etc.; check here if you don't find a certain command or module parameter)

Collaboration with external software is highly encouraged.

GDAL/OGR for import/export to many formats
R statistical software: GRASS-R interface
DXF: v.in.dxf, v.out.dxf, v.in.ogr, v.out.ogr
Matlab/Octave: r.in.mat, r.out.mat, v.in.mapgen, v.in.ascii, v.out.ascii
POV-Ray rendering: r.out.pov, v.out.pov - see also POV-Ray
VMRL: r.out.vrml (3D virtual reality)
GMT - Generic Mapping Tools for cartography: r.in.bin, r.out.bin
Google Earth/KML: v.out.ogr
VTK (Paraview, etc): r3.out.vtk, r.out.vtk, v.out.vtk - see also GRASS and Paraview
Vis5D: r3.in.v5d, r3.out.v5d
QGIS has GRASS Plugin to work with GRASS GIS data and analytical tools inside QGIS

GRASS GIS is made up of modular tools specifically designed for easy scriptability in any number of common scripting languages, see GRASS and Shell

Interface for direct hooks into higher scripting languages (esp. Python), see GRASS and Python and

if "GRASS_BATCH_JOB=/path/to/script.sh" is set GRASS 6+ will run the script as a batch job and exit when it is complete. Start GRASS with the full path to the mapset to avoid the startup menus. See also GRASS and Shell.
