Hullo Guillaume,
yes, starting from an existing geo I want to rotate physical components in
order to manage automatic geometry modifications and mesh generation from an
external executable program.
But following your suggestion what I can do from my external program is to add
the lines:
tmp[] = Physical Surface { xyz } ;
Rotate { { 1. , 0. , 0. } , { 0. , 0. , 0. } , Pi/2. }
{ Surface { tmp[] } ; }
to my .geo file and then generate the mesh, this should work...

Hello Alessandro,
Have a look at the enclosed file for an example of what Christophe was
mentioning. Also, I don't understand what you are trying to achieve "from the
command line". Is it that you generate geometry as a physical entity in one
.geo file and want to rotate it afterwards ? If that is the case, I don't think
this can actually work because there is no input argument that you could use
from the command line to specify with Physical Entity you wish to transform.
This at least will have to be defined somewhere in a .geo file.

I'm afraid this is not clear to me, how can I use this feature from command
line? Thank you.

No, but you can get all the elementary entities making up a physical group
using e.g. "Physical Line {tag}" (it returns a list), which you can then use in
the transformation commands.
