    go test api/cmdb/client_test.go -count=1

  • mac cleanup

    1. brew cleanup 清理不用的 软件包，可能会只保留最新版，实测释放了 3GB 空间
    2. docker Docker.qcow2 在使用过程中会一直增长，如果你是无状态的 docker ，可以 Preferences => resource => advanced => Disk Image Size 调整大小(所有镜像和 docker 都会被删)， 实测释放 14GB 空间
    3. 微信 => 通用 => 存储空间 => 前往清理
    4. 微信 => 备份与恢复 => 管理备份文件
    5. 查找大于 1GB 的单个文件 ( sudo find / -size +1GB )
