Like control key is represented by a '^' in the terminal, what is the equivalent for the command key (mac)?

I am trying to remap my bash shortcuts using stty

For eg

stty eof ^D

But instead of control, I want to use the command key.

EDIT:

Okay so the issue I was trying to solve was that I wanted to interchange command and control keys because I work on osx and linux and the different key combinations cause me a lot of pain.

So I interchanged the modifier keys using osx preferences. But now all the bash shortcuts like Ctrl+C etc had become equivalent of using the key sequences 'cmd+c' - which is not acceptable.

Thankfully iTerm2, supports remapping of modifier keys as well, so for iterm2 I reversed them again which means iTerm2 recognizes command as command and control as control.

So problem solved for now.
