“Command not found” Errors encountered in Gaussian G16

If you encountered errors when running Gaussian

bash: gview.sh: command not found

OR

bash: g16: command not found

OR

$g16/bsd/g16.profile: Permission denied

Usually it is due to the fact that the user is not in the Gaussian permission group.

Your GV and G16 folders should be in a unique Gaussian group. I have created a Gaussian Group called hpc_g16_group and put all the Gaussian users inside this group. Make sure the entire folder and sub folder of g16 and gv is using the same g16 group
