solved “command not found” bootable install usb

When creating a bootable disk on USB in terminal I kept getting “command not found”

best practice is to go to your applications folder in your hard drive under “devices” in finder, right click your install macOS file of choice, show package contents. Open contents, resources folders and double click “createinstallmedia”

file. Copy the line of code which corresponds with all the terminal codes on the support websites beginning with the first / after your username, and use that as the beginning of your code that you put into terminal. In my case the command was not found because it couldn’t find the file, because my root folder was actually in a partition called OSXSSD, which had to be added to the command after /volumes.

i hope this helps someone customize their command to their actual setup!!
