tlmgr-gui: Start a GUI passing an arbitrary X resource string.
$ sudo tlmgr gui -xrm ${xresource}
try on your machine

This command is composed of three parts: "sudo", "tlmgr gui", and "-xrm ${xresource}". Here is an explanation of each part:

  1. "sudo": This is a command used in Unix-like operating systems (such as Linux) to run a command with administrative privileges. By using "sudo" at the beginning of the command, you are indicating that you want to execute the following command (tlmgr) with root or superuser privileges.

  2. "tlmgr gui": "tlmgr" stands for "TeX Live Manager" and is a command-line tool used for managing TeX Live installations. "gui" is a flag or option for "tlmgr" that opens the TeX Live graphical user interface (GUI). By executing "tlmgr gui", you are launching the TeX Live Manager GUI utility.

  3. "-xrm ${xresource}": These are additional arguments provided to the "tlmgr gui" command. The "-xrm" flag is followed by a resource specification or resource file (represented by ${xresource}). Typically, resource files are used to customize the appearance or behavior of graphical applications.

To summarize, the given command runs the TeX Live Manager GUI utility with root privileges and potentially applies additional resource specifications or customization specified in a resource file.
