为什么sed更改而不保存在yaml文件中？

Question

我的命令

sed -e 's,kurtburak,JohnMarkovic,g' < values-override.yaml 

屏幕显示了我所期望的

server:
  configEnabled: true
  config:
    repositories: |
      - type: git
        url: https://github.com/JohnMarkovic/argocd.git
      - name: argo-helm
        type: helm
        url: https://argoproj.github.io/argo-helm

但

cat values-override.yaml 

显示

server:
  configEnabled: true
  config:
    repositories: |
      - type: git
        url: https://github.com/kurtburak/argocd.git
      - name: argo-helm
        type: helm
        url: https://argoproj.github.io/argo-helm

如果我换到

sed -i

得到

sed: no input files

为什么？
