"No such file or directory"

Hi,

I'm new to LIGGGHTS and was trying to run the in.movingMeshGran example on the terminal. The input was "mpirun -np 4 lmp_auto -echo both< in.movingMeshGran" which produced the following output: "in.movingMeshGran: No such file or directory"

What may I be doing wrong? I'm certain the file exists and can open it using TextEdit on Mac to view it.

Thanks
C CH
