sudo rm /lib64/libc.so.6

[linrio]

I make a mistaken that delete the libc.so.6 by sudo rm /lib64/libc.so.6.
I try to run

sudo LD_PRELOAD=/lib64/libc-2.12.so ln -s /lib64/libc-2.12.so libc.so.6
sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

And, it can not rebuild the soft link also:

[llf@k20-1 lib]$ sudo ln -sf /lib64/libc-2.14.so /lib64/libc.so.6
sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

How to address this mistake?
