icc command cannot be found

Hello,

I have a remote machine which has the intel compiler installed already. I can see the /opt/intel/compilers_and_libraries_2018.1.163 and  /opt/intel/parallel_studio_xe_2018.1.038 directories.

But the icc command can not be found. And I have tried to run:

source /opt/intel/bin/compilervars.sh intel64

and 

source /opt/intel/compilers_and_libraries_2018.1.163/linux/bin/compilervars.sh intel64

These attempts didn't figure my problems.

Does anyone have some suggestions?
