为什么linux中的ls -l命令显示总数？这个总数是多少？ [复制]

Question

ls -l 显示文件的长格式以及权限。但是什么总没有。是？

Answer 1

我假设你的意思是以下

$ ls -l
total 1408600
...

如果是这样，答案可以在 ls 手册中找到。我通过在我的 centos 盒子上运行 info coreutils 'ls invocation' 来获得手册。

为了避免你这样做......

For each directory that is listed, preface the files with a line
'total BLOCKS', where BLOCKS is the total disk allocation for all
files in that directory.  The block size currently defaults to 1024
bytes, but this can be overridden (*note Block size::).  The BLOCKS
computed counts each hard link separately; this is arguably a
deficiency.
