Installing AWS CLI Version 2 on Linux

The AWS Command Line Interface (CLI) provides an efficient way to manage AWS services from a Linux terminal. Follow these steps to install AWS CLI Version 2 on a Linux system.

Step 1: Download the AWS CLI Installer

Locate the Installer:
- Open a browser or terminal and search for "Installing AWS CLI Version 2 on Linux".
- Navigate to the official AWS documentation.
Run the Download Command:
- Open your terminal and execute the following command to download the AWS CLI installer zip file:
```
curl "<https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip>" -o "awscliv2.zip"
```
- This command retrieves the AWS CLI installer and saves it as awscliv2.zip in the current directory.

Step 2: Unzip the Installer

Unzip the Downloaded File:
- Use the following command to extract the zip file:
```
unzip awscliv2.zip
```
- If the unzip command is not installed on your system, you can install it by running:
```
sudo apt install unzip      # For Ubuntu/Debian
sudo yum install unzip      # For RHEL/CentOS
```

Step 3: Run the Installer

Execute the Installation Command:
- Run the installer as the root user by using sudo:
```
sudo ./aws/install
```
- This will install the AWS CLI in /usr/local/bin/.

Step 4: Verify the Installation

Check the AWS CLI Version:
- Run the following command to confirm the installation:
```
aws --version
```
- If the installation is successful, you will see output similar to:
```
aws-cli/2.x.x Python/X.x.x Linux/x.x.x
```
- This output confirms that AWS CLI Version 2 is installed and ready to use.

Common Troubleshooting

PATH Issues:
- If aws --version doesn't work, ensure /usr/local/bin is included in your system’s PATH variable.
- Add it to the PATH using the following command:
Add this line to your .bashrc or .zshrc file for persistence.
```
  ```bash
  export PATH=$PATH:/usr/local/bin
  ```
```
Missing Dependencies:
- Ensure that you have curl and unzip installed before proceeding with the installation.
