## NAME

v.info - Outputs basic information about a user-specified vector map layer.
(GRASS Vector Program)

## SYNOPSIS

v.info
v.info help
v.info input=name

## DESCRIPTION

v.info reports some basic information about a user-specified vector map layer and the topology status. This map layer must exist in the user's current mapset search path. Information about the map's boundaries, projection, data type, topology presence, category number, number of lines, areas and islands, data base location and mapset, and history are put into a table and written to standard output. The types of information listed can also be found in the cats, cellhd, and hist directories under the mapset in which the named map is stored.

The program will be run non-interactively if the user specifies the name of a vector map layer on the command line, using the form:

  v.info input=name

  where input is the name of a vector map layer on which the user seeks information. The user can save the tabular output to a file by using the UNIX redirection mechanism (>); for example, the user might save a report on the streams map layer in a file called stream.rpt by typing:

    r.info input=streams > stream.rpt
  Alternately, the user can simply type v.info on the command line, without program arguments. In this case, the user will be prompted for the name of a vector map layer using the standard GRASS parser interface. The user is asked whether he wishes to print the report and/or save it in a file. If saved, the report is stored in a user-named file in the user's home directory.
