vncviewer Command Examples in Linux

vncviewer is a command-line tool that is used to launch a VNC (Virtual Network Computing) client. VNC is a remote desktop sharing system that allows users to connect to and control a graphical desktop environment on a remote system. VNC operates on the client-server model, where the VNC server is installed and running on the remote system, and the VNC client is used to connect to and interact with the server.

vncviewer is a client program that is used to connect to and display the graphical desktop environment of a VNC server. The user can interact with the remote system using their local mouse and keyboard, and the remote desktop is displayed in a window on the local system.

vncviewer provides a number of options and settings that can be used to configure the VNC connection, such as the remote host and port, display resolution, color depth, authentication, and encryption. These options can be specified on the command line or in a configuration file.

vncviewer is typically used in conjunction with a VNC server, which is installed and running on the remote system that the user wants to connect to. There are many VNC server implementations available for different operating systems, such as TightVNC, RealVNC, and TigerVNC.
