Chmod permision

[Galvin]

Hello Support Team,

By mistake I changed chmod permission. I fired the command

chmod 000 /bin/chmod

But now I am not able to give the permission. The error is "-bash: /bin/chmod: Permission denied" Please Help me!

Now How can I change permission?

mv current /bin/chmod and wget same file from another server. Please check OS version.
