How to switch between sftp and Terminal shell

If you are on the sftp> prompt and want to check out something on your Terminal shell from which you logged into SFTP you can do that by using the command ! on the sftp> prompt.

Just type ! on sftp> prompt and I am taken back to my Zsh shell on the macOS, I can do whatever i want to do on the Zsh shell (check files, dir locations, execute script, etc) and when I want to return to the sftp> just type bye

Example: ! and bye to swtich between sftp> and shell

sftp> pwd
Remote working directory: /
sftp> ls 
pub          readme.txt   
sftp> !
.zshenv Startup file read...
