So I plan to use a zenity information message box to output a SHA256 within a "nemo_action". I have tried many different methods to accomplish this - none have so far been successful.
Below is my most recent failure:
zenity --info --title="Check SHA256 for %n" --text="$(sha256sum %f)"
and when added to nemo_actions:
Exec=zenity --info --title="Check SHA256 for %n" --text="$(sha256sum %f)"
Thank you for your time. David.
