Build topology or dump topology or spatial index to stdout
Options: build,dump,sdump,cdump
Default: build
build: build topology

sdump: write spatial index to stdout
cdump: write category index to stdout
DESCRIPTION
v.build builds support files for (binary) GRASS vector data files. These support files supply topology and category information that are needed by other GRASS modules.GRASS is generating these support files automatically, only in rare cases the user has to (re)build them.
Refer to Vector data processing in GRASS GIS for more information on GRASS GIS vector data model.
NOTES
v.build creates support files only for binary vector maps located in the user's current mapset. If vector map is located in another mapset, you need to specify this:
v.build map=geology@PERMANENT
In case of errors, the user can optionally generate an error vector map containing the erroneous vectors for later inspection.
