Appiconupdate

Simple wrapper script around fileicon to update multiple app icons on macOS with one command.

Setup

Prerequisites

fileicon needs to be installed on your system.

$ brew install fileicon

Installation

$ curl -sSL https://github.com/jonafll/appiconupdate/releases/download/v0.3.0/appiconupdate.sh > /usr/local/bin/appiconupdate && chmod 755 /usr/local/bin/appiconupdate

Create a directory for your app icons and place them in it. Icons work best as .icns or .png files with 512x512 pixels.

$ mkdir /path/to/icons

IMPORTANT: The name of the icon files must match the application name within /Applications!

$ ls /path/to/icons
Visual Studio Code.icns     Docker.icns

$ ls /Applications
Visual Studio Code.app      Docker.app

Usage

$ appiconupdate /path/to/icons

Optionally you can set the icon path as environment variable

export ICN_PATH=/path/to/icons

or create an alias.

alias appiconupdate="appiconupdate /path/to/icons"
