You can backup your config files before editing them, like this:

cp configbeingedited.conf configbeingedited.conf__orig_datestring

This way, when things break or don’t function how you like, you can easily copy the original config file back into position, restoring the original functionality.

    Some Zsh:

    bak () {
  emulate -L zsh
  for 1 {
    cp -i $1 $1.bak
    ls -l $1 $1.bak
  }
}

      This is a clean way to make your own new command called ‘bak’, to automate making a second copy of the file.
