Hello Yasuo, If you just need to display line directions with an arrow head on end-node, you can use the "display=dir" option available for d.vect.
If you need to display a custom symbol, you cannot use "icon=" option, which is dedicated to point and centroid features (not lines). Envethough the following case describes a method to compose a hardcopy map, this wiki entry can help you : http://grasswiki.osgeo.org/wiki/Tips_and_Tricks#Compensate_the_lack_of_line_ends_symbology_in_ps.map The idea is to create a point vector where points are assigned a rotation angle value corresponding to the line last (or first) segment orientation. Then you just have to call d.vect whith "icon=" and "rot_column=" options. Good luck!
