Apple - How does the sudo key symbol work?
I get the key symbol when running
read -s in Terminal.
As this seems to work the same for
read -s as for
sudo, I assume this is a feature of Terminal (to display a key symbol whenever input is requested in silent/hidden mode).
The simplest answer is just write the script without sudo
then tell the user to run it with sudo e.g.
the script will run with root privileges
`this has the advantage that the user knows what asks for and where the password is used, if in your script you could be taking a copy or leaving it in memory
