• --session: Connects to the session bus.
• --timeout: Specifies the timeout for the operation.
• --help: Displays help for the command.

Examples of Common Use Cases

GDBus can be used to perform a variety of tasks. Here are some examples of common use cases:

• Sending messages: GDBus can be used to send messages to other applications on the system bus.
• Receiving messages: GDBus can be used to receive messages from other applications on the system bus.
• Calling methods: GDBus can be used to call methods on other applications on the system bus.
• Monitoring signals: GDBus can be used to monitor signals from other applications on the system bus.
• Automating tasks: GDBus can be used to automate tasks on the system bus.

Advanced Options and Flags

GDBus also has a number of advanced options and flags that can be used to customize its behavior. Here are some of the most commonly used ones:

• --verbose: Enables verbose output.
• --xml: Outputs the data in XML format.
• --json: Outputs the data in JSON format.
• --yaml: Outputs the data in YAML format.
• --no-auto-start: Prevents GDBus from automatically starting the bus.

• Monitoring system events: GDBus can be used to monitor system events such as user logins and system shutdowns.
• Automating system tasks: GDBus can be used to automate system tasks such as software updates and system backups.
• Integrating applications: GDBus can be used to integrate applications by allowing them to communicate with each other.
• Debugging applications: GDBus can be used to debug applications by monitoring their communication on the system bus.
• Troubleshooting applications: GDBus can be used to troubleshoot applications by monitoring their communication on the system bus.

Troubleshooting Tips and Potential Errors

When using GDBus, it is important to keep in mind the following troubleshooting tips and potential errors:

• Make sure that the bus type and address are specified correctly.
• Make sure that the timeout is set to a reasonable value.
• Make sure that the user has the correct permissions to access the bus.
