file.yaml文件内容
---
idc_group:
name: bx
bx:
news_bx: news_bx
web3_bx: web3_php-fpm_bx
task: [1,2,3,4,5,6]

(testenv3.) localhost:testenv3. macname$ cat file.yaml | shyaml get-value idc_group.name
bx
(testenv3.) localhost:testenv3. macname$
(testenv3.) localhost:testenv3. macname$ cat file.yaml | shyaml key-values idc_group.bx
news_bx
news_bx
web3_bx
web3_php-fpm_bx
(testenv3.) localhost:testenv3. macname$
