Some common control characters in bash

CTL-Move the cursor to the beginning of the line
CTL-eMove the cursor to the end of the row
CTL-lPage feed (terminal screen clearing), the effect is similar to the clear command (the difference is that the row where the current cursor is not cleared)
CTL-uDelete the characters from the beginning of the row to the current cursor position (excluding the characters at the current cursor position). In the write-down settings, CTL-u deletes the entire row regardless of the cursor position
CTL-WRemoves characters from the current cursor position to the first space.
