For example, image the first two lines are the following: Code: Joe | Doe | 30 Jane | Doe | 28 Peter | Smith | 25 John | Jones | 26 I would like an answer like the following Code: Doe 2 Smith 1 Jones 1 I managed to list the surnames by the following: Code: more FILENAME | awk -F"|" '{print $2}' Moderator's Comments: (HowTos)
