@RyanWhitley To convert polygons to polylines in GRASS:
v.in.ogr dsn=<input>.shp out=chad
v.build.polylines in=chad out=chad2
v.out.ogr type=boundary in=chad2 dsn=grass_chad_lines.shp

@RyanWhitley Here's how you can do it to lines:
v.in.ogr dsn=AdminLine2.shp out=chad
v.clean tool=rmdupl in=chad out=chad2 <--new step to remove dupe segments
v.build.polylines in=chad2 out=chad3
v.out.ogr type=line in=chad3 dsn=grass_chad_lines.shp <-- note "type" is "line", not "boundary"
