After unzipping electrum-2.8.3.tar.gz to a folder, i moved into that forlder in terminal and ran:
./electrum

and i get the error:
./electrum: Permission denied error

I searched and found a suggestion to change permissions on the electrum.py file to make it executable. So I tried that and it seems to have worked, Electrum Wallet has opened. But I just wanted to check if that sounds right to everyone? Would the Electrum package have to have the permissions updated right after unzipping to make it work or am i missing something? That doesn't seem right that it wouldn't already have the correct perms 'out of the box'?

Do the tar.gz files have to be complied? Not sure if this is going in the right direction?

Thanks!
