I have a file called, resources.html and I need this file to goto in a every subdirectory in do_roots directory.
You probably want to create symbolic links to the file rather than copy it, or possibly create hard links to it. To actually COPY, replace XXX below with "cp". To create SYMBOLIC LINKS, replace XXX with "ln -s". To HARD LINK, replace XXX with "ln".
# cd do_roots
# echo "the file contents" > resources.html
# for dir in `find . -type d -print`
XXX resources.html $dir/
