Kubectl Autocomplete in Bash (Linux)
To set up kubectl autocomplete in Bash on Linux, you need to install bash-completion first. Once installed, you can add the completion script to your .bashrc file. This will enable kubectl autocomplete every time you start a new Bash session.

# install bash-completion
sudo apt-get install bash-completion

# Add the completion script to your .bashrc file
echo 'source <(kubectl completion bash)' >>~/.bashrc

# Apply changes
source ~/.bashrc

3 Reasons You Should Use kubectl autocomplete

When working in a command-line environment, every keystroke counts. Here are some benefits of using autocomplete with kubectl:

Efficiency and speed: By predicting and filling in the rest of your commands, it saves you valuable time and keystrokes. You no longer need to type out the full commands, which can be quite lengthy in Kubernetes.
Accuracy: With autocomplete, you minimize the risk of typos and syntax errors that could lead to failed commands or unintended actions.
Learning and discovery: kubectl autocomplete is also a learning tool. If you’re new to Kubernetes, remembering all the commands and their syntax can be daunting. Autocomplete helps you learn these commands and their correct usage, and discover new kubectl commands that you might not have been aware of.
