US>Some files were deleted due to accidental rm-f/* execution

I was going to run rm-f./*, but I turned it off as rm-f/*.

ls is

-bash:/bin/ls —No such file or directory

Also, yum is

-bash:/usr/bin/yum:/usr/bin/python:bad interpreter:No such file or directory

said he.Most commands are unavailable, and wget and so on will cause this error.

-bash:/usr/bin/wget:/lib64/Id-linux-x86-64.so.2:bad ELF interpreter:No such file or directory

The operating system is CentOS 7.

Please tell me what the solution is.

Supplemental
I will give up and reinstall.
However, if you know how to solve this problem, please reply for someone else who has made a mistake.

In the case of CentOS 7/64bit, four symbolic links /lib64, /lib, /bin, /sbin have been deleted, so you can recover by pasting them again.

#/usr/lib64/ld-linux-x86-64.so.2 -- library-path/usr/lib64/usr/bin/ln-s/usr/lib64/lib64
# /usr/bin/ln-s/usr/bin/bin
# ln-s/usr/lib/lib
# ln-s/usr/sbin/sbin

As a reference, there were other distributions already mentioned, so please refer to the link:

As you can see in the link, Ubuntu seems to have busybox installed as a standard, so you can recover using it.

The following are the results of running a similar command on CentOS 7/64bit in a virtual environment:
