Problem with ESXi command "vsish -e set /vmkModules/iso9660/mount $(esxcfg-mpath -b | grep "CD-ROM" | awk '{print $1}')"

vsish -e set /vmkModules/iso9660/mount $(esxcfg-mpath -b | grep "CD-ROM" | awk '{print $1}')

I am  attempting to perform the following mount on a on the new MAC Mini  Superdrive " vsish -e set /vmkmodules/iso9660/mount $ (esxcfg-mpath -b |  grep "CD-ROM" | awk '{print $1}') and getting the folliwng message?

"-sh: syntax error: "(" unexpected"

Thank you,
