How to install old versions of Homebrew formulas and switch between them

Raw

install-old-homebrew-formulas.md

This example uses istioctl as the formula, but this may come in handy for kubernetes-cli, kubernetes-helm, etc.

Find the formula for your executable, e.g. istioctl, and click on the link to GitHub:
```
brew info istioctl | grep Formula
```
Click "Blame" button ("History" will be too large to display).
Hopefully, you can find an earlier versioned commit message... click on it.
Click ... in upper-right of next page, select "View File" from drop-down.
Right-click "Raw" button, and Copy URL Address.

Paste URL into install command, which will look something like:

brew install https://github.com/Homebrew/homebrew-core/raw/af5f8075d6c64e555812ce818e1d52fe0613b030/Formula/istioctl.rb

If all goes well, you should be able to switch between versions. Use this command fragment to find available versions:
```
brew switch istioctl
```
Use complete command to relink and switch to using that version:
```
brew switch istioctl 1.0.5
```

Found this alternative which is more compatible with my brew version(recent):

I recommend using asdf, as described at https://medium.com/@rafik8/using-different-istioctl-versions-when-managing-istio-53710ccc9d7c
