The RustDesk client can do many thing from the command line, though they are not well documented. Running

rustdesk --something

allows you to make modifications to the configuration file(s) in a safe manner.

These parameters (–something above) were found by reading the source code, and I have not tested all of them, so be very careful.

All?

• –silent-install: Will perform an installation without asking any silly questions. Excellent for automated deployments
• –update: Will look for a new version of the desktop and automatically install it, if possible. untested
• –reinstall
• –server
• –remove: assume this will completely remove the software from the system.
• –tray
• –service
• –server
• –import-config 'encrypted string': This appears to allow you to import a configuration from the command line, but on Linux can only be run as root and appears to only update the root user.
• –password: sets a static password which can be used (if configured) instead of/in addition to the randomly generated one.
• –get-id: returns the ID of the workstation (so others can connect to it)
• –check-hwcodec-config: Checks the hardware codec used on the system

Windows Only?

• –uninstall
• –after-install: script to run after installation
• –before-uninstall: script to run before uninstalling
• –extract: Assume this is a download and extract instead of a full installation
• –portable-service: not sure what this does, but it looks like it is to allow some special support features for the client. May have something to do with the following:
