You include a percent sign (%) before a property name to indicate a property variable, as shown in this example.
# /opt/network_aware/echo_server -t %RS_STOP_TIMEOUT -n %RG_NODELIST |
Given the preceding example, Agent Builder might interpret these property variables and launch the echo_server script with the following values.
# /opt/network_aware/echo_server -t 300 -n phys-node-1,phys-node-2,phys-node-3 |
