OSC 0 / OSC 2 — Set Window Title

Sequence	OSC <Ps> ; <title> ST
Ps	0 = icon + window title, 1 = icon only, 2 = window only
Otty support	✓

Description

Sets the window title (and optionally the icon title — Otty treats them as the same).

Ps	Effect
0	Set icon name and window title
1	Set icon name only
2	Set window title only

The most common form is OSC 0. Most shell rcs (zsh precmd, bash PROMPT_COMMAND) emit this on every prompt to keep the tab label informative.

Example

printf '\e]0;%s\a' "deploy-prod"
# zsh equivalent:
print -Pn "\e]0;%~\a"     # title = current directory (compact form)

Try it

otty features try set-title — sets both window (OSC 2) and icon/tab (OSC 1) names. Look at the title bar / tab to confirm.
