@aliuq this looks similar as the problem reported in kubernetes/kubernetes#105587. It was caused by the use of zsh 5.0.x. Is that your case? Zsh 5.1 or higher doesn't have the problem. The problem has also been fixed in Cobra but has not yet been incorporated in kubectl.

Please let us know if this is the problem for you as well.

For info, here is the fix in Cobra: spf13/cobra#1665

@marckhouzam thanks for your reply, I will try upgrade zsh now

[aliuq]

I've created the PR #112362 to fix this issue, but for those still facing this issue after installing Oh My Zsh with kubectl plugin enabled you can run the command below as a patch to fix it in the meantime:
