xdg-user-dirs-update:tldr:e7296

This command is using the xdg-user-dirs-update tool to update and manage user directory locations on a Linux system. Let's break down the command:

xdg-user-dirs-update is the command itself.

--dummy-output "${path-to-dry_run_file}" specifies a dummy output file to which the dry-run output will be saved. The path-to-dry_run_file should be replaced with the actual path where you want to save this dummy output file. The dry-run output shows what changes would be made without actually applying them.

--set ${xdg_user_directory} tells the command that we want to set a new directory location for a specific user directory. ${xdg_user_directory} should be replaced with the desired user directory, for example, DESKTOP, DOWNLOAD, DOCUMENTS, etc.

"${path-to-directory}" represents the path to the new directory location. You need to replace ${path-to-directory} with the actual path where you want to set the new directory location.

Overall, this command is used to update the location of a user directory on a Linux system. The dummy output file is optional and provides a dry-run output for previewing changes before actually making them.
