[Proj] cs2cs syntax help

[nicolas david]

Re

sorry send my previous message before ending

so you have to tranform your cs2cs command from
cs2cs +proj=latlong +datum=WGS84 +to  +proj=utm +zone=51 +datum=WGS84 -r
to
cs2cs +proj=latlong +datum=WGS84 +to  +proj=utm +zone=51 +south
+datum=WGS84 -r
or using epsg dictionnary
cs2cs +init="EPSG:4326" +to  +init="EPSG:32751" -r
