Hi,
Awk command will better, but you can try:
Code:
$ cat comp.txt 
+_id34,brown,car,2006
+_id1,blue,train,1985
+_id73,white,speed_boat,1990
-_id34,brown,car,2006
-_id72,white,plane,2010
-_id73,white,speed_boat,1990

Code:
$ sed 's/[+-]_\([^,]*,\).*/\1/' comp.txt | sort | uniq -u | grep  -f - comp.txt 
+_id1,blue,train,1985
-_id72,white,plane,2010

Regards.
