4.4.2 Applying changes online
If a parameter is writeable, this means that it can be directly applied by using the following syntax:
gpa_ctrl <module_name> <param_path> <new_value>
For example, to disable the alert for the right power supply the user must execute:
gpa_ctrl hald pws/pwsr/disable_alert Yes
If the command returns without any errors, this mean that the changes have been properly
applied. This can be checked by reading back the output of
gpa_ctrl hald pws/pwsr/
4.4.3 Other functionalities
