- select(): 查询 json 数据中符合要求的， == ,!= , >= , <= 等其它
- any(condition): 布尔值数组作为输入，即 true/false，数据为真，则返回 true
- any(generator; condition): generator-json 数据按层级划分 ，condition 条件
cat /tmp/i_cpu_data.json | jq -r '[.values[][1]]|@json' | jq max -r
cat /tmp/i_cpu_data.json | awk 'BEGIN {max = 0} {if ($1+0 > max+0) max=$1} END {print max}'
bash getadminrole_userlist.sh | jq -r '["User","Type","ID"],(.items[] | [.name,.type,.id]) | @csv'
"User","Type","ID"
