I had a need to copy a file "commit-msg" to git folders called "hooks" while preserving permissions. Since there were a lot of these folders this command helped a lot.
find . -type d -name hooks -exec cp -p commit-msg {} \;
Explanation:
find -type -d :: Unix find command for directory
-name hooks :: name of the folders
cp :: Unix copy command
-p :: preserving permissions
{} :: whatever are the results
\; :: end execution
