 # Usage:
 # 1. Direct Script Execution:
 #    This initiates all the RPC services declared under the function openim::rpc::service_name.
-#    Example: ./openim-rpc-{rpc-name}.sh  openim::rpc::start
+#    Example: ./openim-rpc.sh  openim::rpc::start
 # 2. Controlling through Functions for systemctl operations:
 #    Specific operations like installation, uninstallation, and status check can be executed by passing the respective function name as an argument to the script.
-#    Example: ./openim-rpc-{rpc-name}.sh openim::rpc::install
+#    Example: ./openim-rpc.sh openim::rpc::install
 #
 # Note: Before executing this script, ensure that the necessary permissions are granted and relevant environmental variables are set.
