raman.x running slow

[XudongHuai]

I am running the MoS2 example and the bands_mat.x and the ph_mat.x works properly, but the raman.x does not run properly.

The raman.x calculation has been running for a 2 days and no updates in the raman.out file, no .dat file was found as well. I can see the raman.x program in the processes. it is using 0% CPU and 131 kB memory.
I am not sure if this program is still running but I did not see any progress nor any crush/error report.

I think this program is compiled properly otherwise the other two program may not be working.
I am working with Ubuntu 22.04, and my QE version is 7.3.1

I am sorry I just found that it works if I use: rama.x <raman.in> raman.out
instead of : raman.x -i raman.in > raman.out
