If you installed Gromacs in the default location (/usr/local/gromacs) you need 
administrative privileges to write files to this directory and any subdirectory 
of it.  Thus either issue the demo commands as sudo or install Gromacs 
elsewhere.  Note, too, that there are plenty of other tutorials for learning 
Gromacs in addition to the demo:
