frank_rizzo's solution deletes lines 3,4,6,8,9,12,15,16 (any line divisible by 3 or 4)

If you want to delete 3,4,7,8,11,12,15,16 (line 3 & 4 out of every group of 4) then you want:

Code:
awk 'NR%4==1 || NR%4==2' test.nmea > new.file

delete clearinghouse(1m)												  delete clearinghouse(1m)

NAME
delete clearinghouse - Deletes the specified clearinghouse from the local server system SYNOPSIS
cdscp delete clearinghouse clearinghouse-name ARGUMENT
The full name of the clearinghouse. DESCRIPTION
The delete clearinghouse command deletes a clearinghouse from the local server system. CDS does not permit you to delete a cleared clear- inghouse. Before you can delete a cleared clearinghouse, you must recreate it using the create clearinghouse command. The delete clearinghouse command automatically deletes all read-only replicas from a clearinghouse. CDS does not permit you to delete a clearinghouse that contains a master replica. See the DCE Directory Service module of the DCE Administration Guide for more information about handling master replicas when deleting a clearinghouse. Permissions Required You must have write and delete permission to the clearinghouse and administer permission to all directories that store replicas in the clearinghouse. The server principal needs delete permission to the associated clearinghouse object entry and administer permission to all directories that store replicas in the clearinghouse. NOTES
It is recommended that you delete all replicas except the root before issuing this command. This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE. EXAMPLE
The following command deletes a clearinghouse named /.:/sales/Orion_CH from the local server system: cdscp> delete clearinghouse /.:/sales/Orion_CH RELATED INFORMATION
Commands: clear clearinghouse(1m), create clearinghouse(1m), list clearinghouse(1m), set cdscp preferred clearinghouse(1m), show clearing- house(1m), show cdscp preferred clearinghouse(1m) Books: DCE Administration Guide delete clearinghouse(1m)
