you could see some docs' codeblocks use shell rendered well like https://doris.apache.org/zh-CN/community/developer-guide/mac-dev/dev-prepare. but ones use Bash failed like some in https://doris.apache.org/zh-CN/blog/from-presto-trino-clickhouse-and-hive-to-apache-doris-sql-convertor-for-easy-migration

except compilation-arm. it's modified in https://github.com/apache/doris-website/pull/926
