I can think of many examples of this...You can use the ip/if* commands to set your network interface in the here and now, but you can edit a file like /etc/network/interfaces to make the changes permanent.You can set a bash environment variable by exporting it form the shell, or to make it permanent for your account, you can place the same command in .bashrcIn vim you can :set nowrap to make sure the text file you have open doesn't wrap; but you can also add the same command to .vimrc to keep this the same everytime you open vim.So given these examples; what is this called?
How is the ability to do something on the fly and the ability to make that same thing permanent referred to in Unix / Linux?
terminology
The on-the-fly and permanent tags did existed, no such UNIX or Linux specific terms.
