2 예시 1: css

tester@localhost:~$ cat a.css 
.text-lowercase {
  text-transform: lowercase !important;
}

@media print {
  * {
    text-shadow: none !important;
    box-shadow: none !important;
  }
}

.text-uppercase {
  text-transform: uppercase !important;
}

tester@localhost:~$ cat a.css | sed ':a;N;$!ba;s/@media print[^}]\+}[^}]\+}//g'
.text-lowercase {
  text-transform: lowercase !important;
}



.text-uppercase {
  text-transform: uppercase !important;
}

tester@localhost:~$ cat a.css 
.text-lowercase {
  text-transform: lowercase !important;
}

@media print {
  * {
    text-shadow: none !important;
    box-shadow: none !important;
  }
  * {
    text-shadow: none !important;
    box-shadow: none !important;
  }
  * {
    text-shadow: none !important;
    box-shadow: none !important;
  }
}

.text-uppercase {
  text-transform: uppercase !important;
}

tester@localhost:~$ cat a.css | sed ':a;N;$!ba;s/@media print.*}[^}^{]\+}//g'
.text-lowercase {
  text-transform: lowercase !important;
}



.text-uppercase {
  text-transform: uppercase !important;
}

3 예시 2: yaml

리눅스 sed YAML 파일 다루기 문서를 참고하십시오.

tester@localhost:~$ cat pod.yaml
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    name: nginx
spec:
  containers:
  - name: nginx
    image: nginx
    env:
    - name: DEMO_GREETING
      value: "Hello from the environment"
    - name: DEMO_FAREWELL
      value: "Such a sweet sorrow"

값 변경

tester@localhost:~$ cat pod.yaml | sed ':a;N;$!ba;s/\(DEMO_GREETING[^"]\+\)"[^"]\+"/\1"lorem ipsum"/'
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    name: nginx
spec:
  containers:
  - name: nginx
    image: nginx
    env:
    - name: DEMO_GREETING
      value: "lorem ipsum"
    - name: DEMO_FAREWELL
      value: "Such a sweet sorrow"

행 삭제

tester@localhost:~$ cat pod.yaml | sed ':a;N;$!ba;s/\s\+- name: DEMO_GREETING[^:]\+:[^\n]\+//'
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    name: nginx
