No command line output in RustDesk 1.2.3 (Windows)

[silmaril42]

Bug Description

According to the documentation it should be possible to call rustdesk.exe with command line arguments to get certain informations.

The code also strongly suggests, this should be the case.

I was not able to get any output on stdout or stderr when trying these commands:
rustdesk.exe --version
rustdesk.exe --get-id

The command shell returns immediately after those commands. The only output is a new line.

Running the exe with an unknown parameter (eg. rustdesk.exe --abcdefg) behaves as if no parameter was provided: the RustDesk UI is opened if it was not open before.

This behaviour is the same, both as a normal or administrative user.

How to Reproduce

• On Windows, open a command line window (cmd or powershell - doesn't matter which)
• cd into the RustDesk installation directory (eg. "C:\Program Files\RustDesk")
• run rustdesk.exe --version
• run rustdesk.exe --get-id
• Notice that neither command writes any output to the window.

Expected Behavior

• rustdesk.exe --version should write the current version to stdout
• rustdesk.exe --get-id should write the RustDesk ID of the current machine to stdout

Operating system(s) on local side and remote side

I just investigated this further.

Calling rustdesk.exe from a python script using subprocess.run() returns the expected output strings.

Using cygwin, Msys2-64 or Git Bash (based on MINGW64) all work fine and show the expected output.

It seems that only the command line windows inside Windows 11 are not able to transport this information for some reason.

Some more information/investigation :

Once rustdesk is installed, we opened a command line at C:\Program Files\RustDesk

# This will display/return absolutely nothing
rustdesk --get-id
rustdesk --version

# This will work !
rustdesk --get-id | more
rustdesk --version | more

Also, if you do a rustdesk --password 123456 the password is changed but the value doesn't change in the UI !

same problem in Windows 11 (22H2 22621.2506) and version 1.2.1

Try this:

cd $env:ProgramFiles\RustDesk\
$id = .\rustdesk.exe --get-id | Out-String

Works for me in Windows PowerShell with Admin privileges:

PS C:\Program Files\RustDesk> .\rustdesk.exe --version | Out-String
1.2.3

PS C:\Program Files\RustDesk>
