-# kubectx(1)
-
-kubectx is a utility to manage and switch between kubectl(1) contexts.
-
-```
-USAGE:
-  kubectx                   : list the contexts
-  kubectx <NAME>            : switch to context <NAME>
-  kubectx -                 : switch to the previous context
-  kubectx -c, --current     : show the current context name
-  kubectx <NEW_NAME>=<NAME> : rename context <NAME> to <NEW_NAME>
-  kubectx <NEW_NAME>=.      : rename current-context to <NEW_NAME>
-  kubectx -d <NAME>         : delete context <NAME> ('.' for current-context)
-                              (this command won't delete the user/cluster entry
-                              that is used by the context)
-  kubectx -u, --unset       : unset the current context
-```
-
-### Usage
+### Examples

 ```sh
+# switch to another cluster that's in kubeconfig
 $ kubectx minikube
 Switched to context "minikube".

+# switch back to previous cluster
 $ kubectx -
 Switched to context "oregon".

-$ kubectx -
-Switched to context "minikube".
+# start an "isolated shell" that only has a single context
+$ kubectx -s minikube

+# rename context
 $ kubectx dublin=gke_ahmetb_europe-west1-b_dublin
-Context "dublin" set.
-Aliased "gke_ahmetb_europe-west1-b_dublin" as "dublin".
-```
+Context "gke_ahmetb_europe-west1-b_dublin" renamed to "dublin".

-`kubectx` supports <kbd>Tab</kbd> completion on bash/zsh/fish shells to help with
-long context names. You don't have to remember full context names anymore.
-
-----
-
-# kubens(1)
-
-kubens is a utility to switch between Kubernetes namespaces.
-
-```
-USAGE:
-  kubens                    : list the namespaces
-  kubens <NAME>             : change the active namespace
-  kubens -                  : switch to the previous namespace
-  kubens -c, --current      : show the current namespace
-```
-
-
-### Usage
-
-```sh
+# change the active namespace on kubectl
 $ kubens kube-system
 Context "test" set.
 Active namespace is "kube-system".

+# go back to the previous namespace
 $ kubens -
 Context "test" set.
 Active namespace is "default".
+
+# change the active namespace even if it doesn't exist
+$ kubens not-found-namespace --force
+Context "test" set.
+Active namespace is "not-found-namespace".
+---
+$ kubens not-found-namespace -f
+Context "test" set.
+Active namespace is "not-found-namespace".
 ```

-`kubens` also supports <kbd>Tab</kbd> completion on bash/zsh/fish shells.
+If you have [`fzf`](https://github.com/junegunn/fzf) installed, you can also
+**interactively** select a context or cluster, or fuzzy-search by typing a few
+characters. To learn more, read [interactive mode &rarr;](#interactive-mode)
+
+Both `kubectx` and `kubens` support <kbd>Tab</kbd> completion on bash/zsh/fish
+shells to help with long context names. You don't have to remember full context
+names anymore.

-There are several installation options:
+Starting with v0.9.0, `kubectx` and `kubens` **are now rewritten in Go**.  They
+should work the same way (and we'll keep the bash-based implementations around)

- Install bash/zsh/fish [completion scripts](completion/).
-  - For zsh:
-    The completion scripts have to be in a path that belongs to `$fpath`. Either link or copy them to an existing folder.

-    Note that the leading underscore seems to be a convention. If completion doesn't work, add `autoload -U compinit && compinit` to your `.zshrc` (similar to [`zsh-completions`](https://github.com/zsh-users/zsh-completions/blob/master/README.md#oh-my-zsh)).
-    If not using oh-my-zsh, you could link to `/usr/share/zsh/functions/Completion` (might require sudo), depending on the `$fpath` of your zsh installation.

+file. If you use [oh-my-zsh](https://github.com/ohmyzsh/ohmyzsh), load the

+Example with [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh):
+
+```bash
+mkdir -p ~/.oh-my-zsh/custom/completions
+chmod -R 755 ~/.oh-my-zsh/custom/completions
+ln -s /opt/kubectx/completion/_kubectx.zsh ~/.oh-my-zsh/custom/completions/_kubectx.zsh
+ln -s /opt/kubectx/completion/_kubens.zsh ~/.oh-my-zsh/custom/completions/_kubens.zsh
+echo "fpath=($ZSH/custom/completions $fpath)" >> ~/.zshrc
+```
+
+If completion doesn't work, add `autoload -U compinit && compinit` to your
+`.zshrc` (similar to
+[`zsh-completions`](https://github.com/zsh-users/zsh-completions/blob/master/README.md#oh-my-zsh)).
+
+If you are not using [`oh-my-zsh`](https://github.com/ohmyzsh/ohmyzsh), you
+could link to `/usr/share/zsh/functions/Completion` (might require sudo),
+depending on the `$fpath` of your zsh installation.
+
+In case of errors, calling `compaudit` might help.

Ahmet Alp Balkan	4c9e8fb81e	feat: add -s/--shell flag for scoped sub-shell (#461 ) Spawns an isolated sub-shell with a minimal kubeconfig containing only the specified context. This allows the user to launch a shell where they can only interact with a single cluster without having to worry about a command or an LLM agent interacting with other contexts. Inside the isolated shell, most context switching/editing operations on kubectx are blocked. Nested shells not allowed. Fixes #12.

peter woodman	ff2f9661a2	stop using XDG_CACHE_HOME as home directory (#299 ) * stop using XDG_CACHE_HOME as home directory XDG_CACHE_HOME is not a substitute for $HOME, see [1].
