    Hi folks,

    I just had a question more out of curiosity than anything else...

    For the Terminal command to create a bootable installer, what does "--nointeration" mean at the end:

    sudo /Applications/Install\ macOS\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ --nointeraction

    Also, I've seen another site add an extra bit. They have the same as above except at the end it is "--nointeraction &&say Done". What does "&&say Done" mean?

    I don't use Terminal much and was just curious :)

    Thank you

    The "--nointeraction" keeps createinstallmedia from asking you if you're sure.

    The "&& say Done" is a conditional second command that will speak the word "Done" if-and-when the first completes successfully. You can try just the "say Done" to check it out (or have it say whatever you want).
