The Linux Terraform installation script is as follows:
TERRAFORM_VERSION="0.12.8" #Update with your desired version
curl -Os https://releases.hashicorp.com/terraform/${TERRAFORM_VERSION}/terraform_${TERRAFORM_VERSION}_linux_amd64.zip
&& curl -Os https://releases.hashicorp.com/terraform/${TERRAFORM_VERSION}/terraform_${TERRAFORM_VERSION}_SHA256SUMS
&& curl https://keybase.io/hashicorp/pgp_keys.asc | gpg --import
&& curl -Os https://releases.hashicorp.com/terraform/${TERRAFORM_VERSION}/terraform_${TERRAFORM_VERSION}_SHA256SUMS.sig
&& gpg --verify terraform_${TERRAFORM_VERSION}_SHA256SUMS.sig terraform_${TERRAFORM_VERSION}_SHA256SUMS
&& shasum -a 256 -c terraform_${TERRAFORM_VERSION}_SHA256SUMS 2>&1 | grep "${TERRAFORM_VERSION}_linux_amd64.zip:sOK"
&& unzip -o terraform_${TERRAFORM_VERSION}_linux_amd64.zip -d /usr/local/bin
This script does the following:

The following screenshot displays an execution of the script for installing Terraform on Linux:
In the execution of the preceding script, we can see the download of the Terraform ZIP package (with the curl tool) and the unzip operation of this package inside the /usr/local/bin folder.
We have just seen the installation of Terraform on Linux; now, let's look at its installation on Windows.
