13       v.select help
14       v.select  [-t] ainput=name  [atype=string[,string,...]]   [alayer=inte‐
15       ger]  binput=name  [btype=string[,string,...]]   [blayer=integer]  out‐
16       put=name  [operator=string]   [--overwrite]  [--verbose]  [--quiet]
17
18   Flags:
19       -t
20           Do not create attribute table
21
22       --overwrite
23           Allow output files to overwrite existing files
24
25       --verbose
26           Verbose module output
27
28       --quiet
29           Quiet module output
30
31   Parameters:
32       ainput=name
33           Name of input vector map
34
35       atype=string[,string,...]
36           Type
37           Feature type(s)
38           Options: point,line,boundary,centroid,area
39           Default: point,line,boundary,centroid,area
40
41       alayer=integer
42           Layer number
43           A  single  vector map can be connected to multiple database tables.
44           This number determines which table to use.
45           Default: 1
46
47       binput=name
48           Name of input vector map
49
50       btype=string[,string,...]
51           Type
52           Feature type(s)
53           Options: point,line,boundary,centroid,area
54           Default: point,line,boundary,centroid,area
55
56       blayer=integer
57           Layer number
58           A single vector map can be connected to multiple  database  tables.
59           This number determines which table to use.
60           Default: 1
61
62       output=name
63           Name for output vector map
64
65       operator=string
66           Operator  defines  required relation between features. A feature is
67           written to output if the result of operation 'ainput operator  bin‐
68           put'  is  true. An input feature is considered to be true, if cate‐
69           gory of given layer is defined.
70                 overlap: features partially or completely overlap
71           Options: overlap
72           Default: overlap
73

DESCRIPTION

75       v.select allows the user to select features from a vector  by  features
76       from another one.
