gmtinfo leg-ids

gmtinfo reports the minimum/maximum coordinates, year of the cruise, leg id, number of records, the number of gravity, magnetics, and bathymetry points found, and the start/stop dates for the leg. All the information is written to standard output on one line so that it is easy to use awk to add up numbers etc.

leg-ids

Can be one or more gmtleg-names, like c2610. Use ‘cat list_of_legs‘ to pass all the legnames in the file list_of_legs.

To obtain information about cruises c2603 and v2819, run
