du -h 的时候显示 921.2G 可是 du 的时候显示 1931852288
怎么数也对不上啊？咋回事？

看 man ，du 的默认输出单位是 sector ，也就是 512 字节，1931852288 乘以 512 字节的结果没啥问题

@azev Posix compliant 的单位是 512 bytes ，所以 GNU du 设置了 POSIXLY_CORRECT=1 的话就会用 512 bytes ，BSD du 也一般是 default to 512 bytes
> The use of 512-byte units is historical practice and maintains compatibility with ls and other utilities in this volume of POSIX.1-2017. This does not mandate that the file system itself be based on 512-byte blocks. https://pubs.opengroup.org/onlinepubs/9699919799/utilities/du.html#RATIONALE |
