v.clip module enables extracting those features of input vector map, which overlay features of clip map, as well as their storing in a new vector map.
In default, boundaries of clip map are dissolved before clipping. Alternatively, flag -d can be ticked to retain the boundaries of clip map. Flag -b facilitates clipping by current computational region.
It is possible to clip vector maps consisting of points, lines, areas or combinations of these. However, the current version does not fully support clipping of mixed geometry containing points. In such a case, the output map will only store clipped lines and/or areas.

v.clip is a front-end to v.overlay, as well as v.select. Clipping of areas and/or lines can be achieved using v.overlay. Clipping of points can be performed with v.select.

Clip railroads by counties Wake and Johnston in North Carolina (North Carolina data set).
 
v.extract input=boundary_county where="NAME=’WAKE’ OR NAME=’JOHNSTON’" output=county_WAKE_JOHNSTON
v.clip input=railroads clip=county_WAKE_JOHNSTON output=railroads_WAKE_JOHNSTON
 
Figure: v.clip example - basic use

v.clip -d input=railroads clip=county_WAKE_JOHNSTON output=railroads_WAKE_JOHNSTON

Clip hospitals by computational region adjusted to counties Wake and Johnston in North Carolina (North Carolina data set). It is not obligatory to enter name of clip map. In case it is stated, the clip map will be omitted.
 
v.extract input=boundary_county where="NAME=’WAKE’ OR NAME=’JOHNSTON’" output=county_WAKE_JOHNSTON
v.clip -r input=hospitals output=hospitals_clip
