Is there a *Nix utility by which I could append content to a file (say, append the content of a template file into the end of a second file), only if the content isn't already available in the second file, partially or fully?



One could use this grep solution but I find the code there a bit complicated at the moment and would prefer a dedicated utility if there is one.
