linux sed命令怎么通过正则删除多行？

Question

文本：

subjects:
#start-hyj# csacsa
- apiGroup: rbac.authorization.k8s.io
  kind: User
  name: hyj
#end-hyj#
#start-aaa# csacsa
- apiGroup: rbac.authorization.k8s.io
  kind: User
  name: aaa
#end-aaa#
#start-bbb# csacsa
- apiGroup: rbac.authorization.k8s.io
  kind: User
  name: bbb
#end-bbb#

正则：(#start-aaa#)(.|\n)+(#end-aaa#)

运行后没有删除，正则是正确的
