……命令行选项，符合单一 UNIX 规范（Single Unix Specification）里的准则。（实际上很多年前，在第一个 POSIX 规范出台之前，我就从埃里克·福克斯利一本名为《Unix for Super Users》的书里学到了这些理念，书里有个关于命令行选项语法的附录。）* http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_... 当然，如果用户想把所有可用核心都跑满，那么……

……对于 cp 命令而言，尽管大多局限于那些使用 getopt/popt 解析参数的程序，这在各处都有详细说明。我最早是在埃里克·福克斯利写的一本出版于 1985 年名为《UNIX for Super-Users》的书里见到的。* 在 Unix 和 Linux Stack Exchange 上总有人问这个问题，从将近十年前的 https://unix.stackexchange.com/q/11376/5132 到 https://unix.stackexchange.com/q/570729/5132……

我书架上有本书，埃里克·福克斯利的《Unix for Super-Users》。1985 年出版的，它在第 52 页回答了这个问题，也是索引里“lost+found”词条列出的第一页。这肯定不是最早提到它的书籍吧，对不对？（肯定会出现在……
I have a book on my bookshelf, Eric Foxley's Unix for Super-Users. It was published in 1985, and it answers this question on page 52, the first page listed for the entry 'lost+found' in its index. This is surely not the earliest book mention, is it? (It'll be in…
Foxleys book does not actually claim reason why it need to be preallocated. I've got the book also. Index mentions fsck only page 52, where it reads: "52 UNIX FOR SUPER-USERS ... The filestore consistency check is performed by the command fsck (usu- ally stored as /etc/fsck, but sometimes in /bin), which should be used to check all discs used as file-systems. It defaults…

福克斯利的书里其实并没有说明它为什么需要预先分配空间。我也有这本书。索引里提到 fsck 的只有第 52 页，上面写着：“52 UNIX FOR SUPER-USERS ... 文件存储的一致性检查由 fsck 命令执行（通常存放在 /etc/fsck，但有时在 /bin），应该用来检查所有作为文件系统使用的磁盘。它默认……
