Git Bash
:wq
Explanation
- : ( colon symbol ) is the beginning character in the execution sequence.
- w stands for write, as you would like the system to overwrite the former state of your file with this newer state.
- q is for quit, as after the system has done overwriting your file, proceed to exit out of the editor.
Result
Your window will revert back to the terminal/command prompt screen for further commands.
