The command and resource completion is built into oc client. At the time of writing this, you can generate it for bash, zsh, fish, powershell.

## Generate completion file

Invoke the following command to generate completion file for your favourite shell:

```shell
source <(oc completion bash)
source <(oc completion zsh)
oc completion fish | source
```

Or permanently store it in a file and source it from `.bashrc`.
Make sure to frequently update it

```bash
oc completion bash > oc_completion.sh

# In .bashrc
source oc_completion.sh
```

There is also completion for `powershell`, but I will leave it to you to check it out.

## Documentation
Check `oc completion --help` to get full documentation about the feature with few more examples.
It is constantly evolving, so it is good to revisit from time to time.

## Environment

The commands were executed using <OpenShiftLocal/> and the following client/server versions of OpenShift.

<KubeBadge client='4.10.9' server='4.10.9' kubernetes='v1.23.5+9ce5071'/>
