Error in generating EMIF IP example design with tcl

hi all,

The following lines i have taken from emif ip example design user guide

"To create a compilable project, you must run the quartus_sh -t make_qii_design.tcl script in the destination directory.
To create a simulation project, you must run the quartus_sh -t make_sim_design.tcl script in the destination directory."

but while running the command in tcl window i got the following..

quartus_sh -t make_qii_design.tcl
Error:invalid command name "quartus_sh"
Error: while executing
Error:"unknown_original quartus_sh -t make_qii_design.tcl"
Error: ("eval" body line 1)
Error: invoked from within
Error:"eval unknown_original $cmd $args"
Error: (procedure "::unknown" line 7)
Error: invoked from within
Error:"quartus_sh -t make_qii_design.tcl"

kindly help me to get this.

Regards
