Erase below (ED 0)
ESC [ 0 JED 0 erases from the cursor position to the end of the screen. The sequence is
ESC [ 0 J or ESC [ J (parameter defaults to 0). Commonly used to clear the screen below a status bar or after repositioning content.
ED 0 is the default ED operation and one of the most common screen-cleanup sequences. Shell prompts, pagers, and TUIs use it after moving the cursor to a known point so stale content below the new layout disappears. Like other erase operations, it should leave cursor position unchanged.How this is testedautomated
