kubectl Shell Autocompletion
The kubectl shell autocompletion extension lets you extend the Tab key completion feature of Bash and Zsh shells to the kubectl commands. While not a troubleshooting tool, this extension can make troubleshooting easier, because it lets you enter kubectl commands more easily.
For more information about the Kubernetes autocompletion extension, see Enabling shell autocompletion in the Kubernetes documentation.
Note that to install the autocompletion extension in Bash, you must be running version 4 or later of the Bash shell. To determine your bash shell version, run the bash --version command.
