i was trying to run

sudo rm -r ./tmp

but instead typed

sudo rm -r /tmp

Will it be fixed by running?

sudo mkdir /tmp

if i do what permissions should i give it?

I can't think of a reason why this shouldn't work. On my system, the permissions are set by:

sudo chmod 1777 /tmp

I rebooted my system after deleting the /tmp folder and now it is not getting past lightdm. – Juzer Ali Dec 5 '12 at 4:49

You should run the following commands to restore the tmp folder.

sudo -i
# You now have a root prompt and do not need to continue typing sudo
mkdir /tmp
chmod 1777 /tmp

Then you sould be all good

I think that exiting the root prompt after the steps would be worth mentioning. – zxcdw Aug 22 '12 at 0:34
