What is the command for SSH X11 forwarding?

The command for SSH X11 forwarding is executed using the option that specifies the -X flag. This allows for the forwarding of X11 sessions over an SSH connection, enabling graphical applications to be run on a remote server while displaying the interface on the local machine.

When you use SSH with the -X option, it ensures that the necessary X11-related authentication tokens are set up, which allows the remote application to open its graphical user interface and send it back to the local display. This is particularly useful for users who need to run graphical applications on remote servers securely.

The other options do not perform X11 forwarding. For instance, while -Y also supports X11 forwarding, it allows for untrusted applications, providing a different level of security. The -F option is used to specify an alternative configuration file for SSH, and -Z is not a valid option related to SSH X11 forwarding. Thus, the choice using -X is essential for enabling and properly configuring X11 forwarding with SSH.
