Bagaimana cara menghapus tong usang dari Homebrew?

Saya menggunakan tong-tong homebrew untuk memperbarui ekosistem aplikasi saya. Sangat bagus ketika memelihara beberapa komputer di rumah, bepergian atau bepergian.

Namun, ketika beberapa paket diperbarui (seperti Google Chrome), saya akhirnya menginstal versi bersamaan yang berbeda (dan yang dilihat oleh OS):

$ ls / opt / homebrew-cask / Caskroom / google-chrome / stable-channel terbaru

Ini terjadi ketika memutakhirkan tong:

$ ls -l /opt/homebrew-cask/Caskroom/tunnelblick
total 0
drwxr-xr-x 5 foo staff 238 Mar 11 07:42 3.3.0
drwxr-xr-x 5 foo staff 238 May 13 13:53 3.3.2
[13:00:40] foo at bar in ~
$ brew cask install --force tunnelblick
==> Caveats
For security reasons, Tunnelblick must be installed to /Applications and will request to be moved at launch.

Bagaimana saya hanya menyimpan yang terbaru?

Di Terminal, ketik:

for app in $(brew cask list); do cver="$(brew cask info "${app}" | head -n 1 | cut -d " " -f 2)"; ivers=$(ls -1 "/opt/homebrew-cask/Caskroom/${app}/.metadata/" | tr '\n' ' ' | sed -e 's/ $//'); aivers=(${ivers}); nvers=$(echo ${#aivers[@]}); echo "[*] Found ${app} in cask list. Latest available version is ${cver}. You have installed version(s): ${overs}"; if [[ ${nvers} -eq 1 ]]; then echo "${ivers}" | grep -q "^${cver}$" && { echo "[*] Latest version already installed :) Skipping changes ..."; continue; }; fi; echo "[+] Fixing from ${ivers} to ${cver} ..."; brew cask uninstall "${app}" --force; brew cask install "${app}"; done

Petunjuk: Salin dan tempel baris perintah di atas ke Terminal.
