Output seen when installing Quartus

When I tried to install Quartus Web version, I got the following output. I am not sure what to do next.

./11.1sp2_259_quartus_free_linux.sh 
Creating directory 11.1sp2_259_quartus_free_linux
Verifying archive integrity... All good.

   ./setup --help 
for commandline usage.

I would not even hazzard a guess as to what caused this.

Any help apprerciated. Thanks in advance.
