```
Input file
           - name: APPENV
             value: STAGING
           - name: ELASTICSEARCH_USER
             value: elastic
           - name: WRITE_LOGS_TO_ELASTICSEARCH
             value: "true"
           - name: version
             value: "5"

```

Expected output:

```
APPENV: STAGING
ELASTICSEARCH_USER: elastic
WRITE_LOGS_TO_ELASTICSEARCH: "true"
version: "5"

```

tried `awk -F "e:" '{print $2}' filename` to abstract only key and value, but need to align this as above output. Any help would be appreciated
