Jean Louis,

Take a look at the documentation for cs2cs. I believe it should answer all your questions regarding cs2cs.
Here it is: https://proj.org/apps/cs2cs.html

Subject: [PROJ] How to construct proper cs2cs command line arguments

Hello,

I have been using this: https://mygeodata.cloud/cs2cs/

and I used input:

+proj=longlat +datum=WGS84 +no_defs

or EPSG:4326

and output to be:

+proj=utm +zone=36 +ellps=clrk80 +towgs84=-160,-6,-302,0,0,0,0 +units=m +no_defs

or Arc 1960 / UTM zone 36N (EPSG:21096)

then with coordinates:

-1.122159, 29.714413

I could get 134183.400916;-123935.185151

which looks proper to me.

But how exactly do I construct the cs2cs command line?

Jean
