twm:tldr:c8304
This command is related to the "twm" window manager.
The "twm" command is used to start the "Tab Window Manager" on the X Window System. It is a lightweight window manager that provides basic functionality for managing windows and virtual desktops.
The "-f" flag is used to specify a custom resource file for twm. A resource file contains configuration options and settings for twm, such as window decorations, keybindings, and window behavior. By using the "-f" flag followed by "${filename}", you can specify the path to the desired custom resource file.
So, when you run the command "twm -f ${filename}", you are instructing the twm window manager to start using the specified resource file for configuration, instead of the default settings. This allows you to customize the behavior and appearance of twm according to your preferences by providing a custom resource file.
