brew-cask-upgrade

brew-cask-upgrade is a command-line tool for upgrading every outdated app installed by Homebrew Cask.

Homebrew Cask extends Homebrew and brings its elegance, simplicity, and speed to the installation and management of GUI macOS applications and large binaries alike.

brew-cask-upgrade is an external command to replace the native upgrade by offering interactivity, an improved interface, and higher granularity of what to upgrade.

Installation

brew tap buo/cask-upgrade

Verification of installation

In order to simply verify that brew cu is correctly installed, you can simply run brew tap command and see if the repo is included:

> brew tap
buo/cask-upgrade
homebrew/bundle
homebrew/cask
homebrew/core

Uninstallation

brew untap buo/cask-upgrade

Usage

Upgrade outdated apps:

brew cu

Upgrade a specific app:

brew cu [CASK]

While running the brew cu command without any other further options, the script automatically runs brew update to get latest versions of all the installed casks (this can be disabled, see options below).

It is also possible to use * to install multiple casks at once, i.e. brew cu flash-* to install all casks starting with flash- prefix.

Apps with auto-update

If the app has the auto update functionality (i.e. they ask you themselves if you want to upgrade them), they are not upgraded while running brew cu and will display a PASS result. If you want to upgrade them, pass the -a or --all option to include also those kind of apps.

Please note, that if you update the apps using their auto-update functionality, that change will not reflect in the brew cu script! Tracked version gets only updated, when the app is upgraded through brew cu --all.

Display usage instructions:

brew help cu

Interactive mode

When using interactive mode (by adding --interactive argument or confirming app installation with i) will trigger per-cask confirmation. For every cask it is then possible to use following options:

• y will install the current cask update
• N will skip the installation of current cask
• p will pin the current version of the cask (see version pinning)

Version pinning

Pinned apps will not be updated by brew cu until they are unpinned. NB: version pinning in brew cu will not prevent brew cask upgrade from updating pinned apps.
