It shouldn't generate output. It will make your system find your gromacs installation, however. Try e.g. "which mdrun".

Thanks for your answer Justin. I followed your advice:
When I type
*$ source /usr/local/gromacs/bin/GMXRC*
*$*

Nothing happened, the prompt returns normally and no action is executed. Do
you have any idea?

Note the first error - you need to source the file.

$ source /usr/local/gromacs/bin/GMXRC
