README.md

resize.js

This script lets you resize the active Terminal.app window from the CLI. If no values are specified it'll use the current profile's default size.

Usage

Set width and height:

$ resize 120 24

Reset to the current profile's default size:

$ resize

Installation

1. Add ~/.local/bin/ to your PATH.
2. Save resize.js to ~/.local/bin/.
3. Make it executable: chmod +x resize.js.
4. Create a symlink so you don't have to type .js: ls -s resize.js resize
