服务器被入侵，ls -a 无法显示目录下特定文件
新学linux
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
无法显示特定文件名的文件，如 :/usr/lib/local/crtres_c 及同目录下其他未知文件
[root@localhost ~]# ls -ahil /usr/lib/local/
total 4.0K
537535787 drwxrwxrwx. 2 root root 42 Feb 3 09:43 .
268435585 dr-xr-xr-x. 45 root root 4.0K Jan 18 00:23 ..
[root@localhost ~]# ls -ahil /usr/lib/local/crtres_c /usr/lib/local/test
ls: cannot access /usr/lib/local/test: No such file or directory
537535781 -rw-r--r--. 1 root root 0 Feb 3 09:43 /usr/lib/local/crtres_c
rm -rf * 无效
[root@localhost ~]# rm -rf /usr/lib/local/*
[root@localhost ~]# ls -ahil /usr/lib/local/crtres_c /usr/lib/local/test
ls: cannot access /usr/lib/local/test: No such file or directory
537535781 -rw-r--r--. 1 root root 0 Feb 3 09:48 /usr/lib/local/crtres_c
文件可删除
[root@localhost ~]# rm -rf /usr/lib/local/crtres_c
[root@localhost ~]# ls -ahil /usr/lib/local/crtres_c /usr/lib/local/test
ls: cannot access /usr/lib/local/crtres_c: No such file or directory
ls: cannot access /usr/lib/local/test: No such file or directory
新建同名文件，同样无法显示
[root@localhost ~]# touch /usr/lib/local/crtres_c /usr/lib/local/test
[root@localhost ~]# ls -ahil /usr/lib/local/
total 4.0K
537535787 drwxrwxrwx. 2 root root 54 Feb 3 09:48 .
268435585 dr-xr-xr-x. 45 root root 4.0K Jan 18 00:23 ..
537535785 -rw-r--r--. 1 root root 0 Feb 3 09:48 test
[root@localhost ~]# ls -ahil /usr/lib/local/crtres_c /usr/lib/local/test
537535781 -rw-r--r--. 1 root root 0 Feb 3 09:48 /usr/lib/local/crtres_c
537535785 -rw-r--r--. 1 root root 0 Feb 3 09:48 /usr/lib/local/test
求怎么实现的，怎样能正常显示所有文件！
