Reset is a command line tool used to restore a terminal to its default settings. It clears any customized configurations made to the terminal and brings it back to the default state. This includes resetting the prompt, clearing the screen, and setting the cursor position to the top left corner. Reset is primarily used when the terminal gets into a state where the display becomes garbled or unreadable. It can also be useful when experimenting with terminal settings and wanting to quickly restore the default configuration. Reset does not change any settings outside of the current terminal session and does not delete any files or data. It is a simple and efficient way to fix display issues and start fresh with a clean terminal environment.
