Is there a built-in way to both save and copy a screenshot to the clipboard at the same time? From what I've seen it seems like the basic hotkeys do not allow such a thing, besides if I use the following command on the terminal :

screencapture -ci somepath/screenshot.jpg


It only copies the screenshot to the clipboard but doesn't create the file screenshot.jpg at all (-c copies to clipboard and -i makes the user select a rectangle region to capture)

Thanks for your help.

The description of the command uses the word 'or' to indicate that only one action is possible: save the screencapture to a file or to the clipboard:
