I've incorporated this into a script that grabs the most recent versions - thanks so much! https://github.com/ryanmaclean/awful-bash-scripts/blob/master/install_recent_terraform_packer.sh

thanks for this! very helpful

Glad this helped as a starting point. Updating this one to reflect additions/changes that @ryanmaclean made. 👍 Thanks for making it better! I've also added logic to pick between Darwin and Linux binaries.

Came across this as I was creating my script. I wrote a version that will grab most Hashicorp programs and install with the options you specify. https://gist.github.com/elocnatsirt/220c83398a67e2f18477dba3c1aeedf9

Hope this helps anybody looking for/to create a similar script.

@Adron, thanks for this useful script. I would like to use it and include a copy in my repository, under which license terms is published? maybe MIT? Apache software license? GPL ? or something similar?

This script only installs terraform version 0.9.9 and the latest is 0.11.2, so it is not getting the latest version of terraform.

Like a few others in this thread, I came across this after creating my own terraform-installation-script.

If anyone is interested - my script will install the latest version or a specific version (if there are breaking changes you want to avoid).

@jmalibre - my script is MIT license if it works for you. I'm open to changes you may need.

Out of everything I have tried @robertpeteuil's looks like the best solution

I don't (as some have noticed) maintain this script anymore, check out @robertpeteuil's script instead. It's here -> https://github.com/robertpeteuil/terraform-installer
