Unable to run any command on mac terminal

I have changed by mistake the mode of /usr to 644 on my mac from terminal so now non of my process is accessible.

I can't use sudo and I am unable to find any way to login as root user so I will be able to change /usr's mode back to 777.

Please give me any suggestion

Here is the error it shows when I open new tab in terminal.

could not create a new process and open a pseudo-tty

I followed trojanfoe's suggestion. Here are the steps to fix this issue:

On system boot press Command+R it will take you to OS X Recovery
Click on Repair Disk Utility
Select your disk where os is installed
Click on repair file permissions

It will repair your permissions now you just need to restart your mac.
