I have an older version of software that I once manually installed through installation package (version 0.6.6 -- I write it down here for later discussion purpose, but the version number is not relevant to this question).
Now I found brew is better why to manage the update/upgrade etc. So, I use brew to install the software by doing
brew install terraform (version 0.6.9 -- again, I write it down here for later discussion purpose, but the version number is not relevant to this question), which is all good so far.
However, when I do
terraform version to query the current effective version, I found it's still the old version.
My question is how I can make the brew installed software take over.
A side question is that which I try to find out terraform's location, by run
which terra (hit tab now), which I normally do for other software, the tab won't do the auto complete action for me. Why is that?
