RIS — Reset to Initial State (full terminal reset)

Hard reset the terminal: clear screen + scrollback, reset every mode and SGR, home the cursor.

Byte forms

Every common string-literal form so you can paste-and-search either direction.

Description

Reset to Initial State. Two bytes — ESC (0x1b) followed by `c` (0x63) — with no CSI introducer, no parameters. The terminal does the moral equivalent of a power cycle: clears the screen and (on most terminals) the scrollback, resets every SGR attribute and color, exits the alt screen, resets DEC private modes (auto-wrap on, cursor visible, mouse off, bracketed-paste off), resets character sets, and homes the cursor. This is what `reset(1)` and `tput reset` ultimately emit. Use it as a last-resort recovery when a crashed TUI has left the terminal in an unusable state — but be aware it also wipes scrollback in most modern terminals, which the gentler `\x1b[!p` (DECSTR, soft reset) does not.

Spec citation: ECMA-48 §8.3.105 (RIS) / xterm-ctlseqs (ESC c)

Examples

fmt.Print("\x1bc")

printf("\x1bc");
