How do I exit my git commit message? I’m NOT in the VIM, I used the ” commit -m ” command

You won’t lose commits by closing the terminal.

ctrl+c will exit the prompt >

What happened was you opened up a string with the odd number of ' characters.
Bash expects more input for your string, and allows you to enter it after the > prompt.

Try typing ' and hit return, you will get the same thing. If you close the string by typing ‘`’ again, you will be back to your normal bash prompt.
