Question

I’m looking for a tool that will, in bulk, add a license header to some source files, some of which already have the header. Is there a tool out there that will insert a header, if it is not already present?

Edit: I am intentionally not marking an answer to this question, since answers are basically all environment-specific and subjective

#!/bin/bash  for i in *.cc # or whatever other pattern... do   if ! grep -q Copyright $i   then     cat copyright.txt $i >$i.new && mv $i.new $i   fi done
