 ```
 
+I’m using the follows:
+
 ```console
 set -g status-right "#(kube-tmux -separator=':' -ctxFg='colour011#,bright' -ctxBg 'default' -sepFg 'colour015#,bright' -nsFg 'colour075#,bright')"
 ```

+```console
+$ kube.tmux
+#[fg=blue]⎈ #[fg=colour]#[fg=]gke_asia-northeast1_cluster#[fg=colour250]:#[fg=]kube-system
+
+$ kube-tmux -separator=':' -ctxFg='blue' -sepFg 'colour250' -nsFg 'default'

+- `go version`
+  - `go version devel go1.17-543e098320 Wed May 5 19:17:46 2021 +0000 X:staticlockranking darwin/amd64`
+- tmux `default-shell` is `/bin/sh`.
+- On darwin, `"echo 3 > /proc/sys/vm/drop_caches"` similar command is `"sync && sudo purge"`
