linux – 为什么在运行ls时隐藏此文件？

几个星期以来,我无法弄清楚为什么我无法删除这个特定文件.
作为root我可以,但我的shell脚本作为不同的用户运行.所以我去运行ls -la并且它不在那里.但是,如果我将其称为参数,它会显示出来！果然,所有者是root,因此我无法删除.

注意,6535丢失了……

[root@server]# ls -la 653*
-rw-rw-r--  1 svn svn  24002 Mar 26 01:00 653
-rw-rw-r--  1 svn svn   7114 Mar 26 01:01 6530
-rw-rw-r--  1 svn svn   8653 Mar 26 01:01 6531
-rw-rw-r--  1 svn svn   6836 Mar 26 01:01 6532
-rw-rw-r--  1 svn svn   3308 Mar 26 01:01 6533
-rw-rw-r--  1 svn svn   3918 Mar 26 01:01 6534
-rw-rw-r--  1 svn svn   3237 Mar 26 01:01 6536
-rw-rw-r--  1 svn svn   3195 Mar 26 01:01 6537
-rw-rw-r--  1 svn svn  27725 Mar 26 01:01 6538
-rw-rw-r--  1 svn svn 263473 Mar 26 01:01 6539

现在它显示你是否直接调用它.

[root@server]# ls -la 6535
-rw-rw-r--  1 root root 3486 Mar 26 01:01 6535

这里有一些有趣的东西.所以我发现了这个问题,因为在我的shell脚本中,它将无法删除,因为6535由root拥有.运行“rm -rf”后,文件实际显示出来.我之前尝试过,它无法删除目录,因为它告诉我目录不是空的.我进去看了看,肯定的是,文件“6535”终于出现了.不知道为什么会这样做.

strace说以下
