How can I change a file with Chef?

Question

I have 7 files and 1 war. I need to change values when I deploy them. I have this:

##usuario
#alfresco.user=*****
alfresco.user=********
##pass 
#alfresco.p

Here is an example of how you can use Chef to uncomment a line in a configuration file. The ruby_block is protected with a ::File::grep. The test for Debian is just for fun.

pam_config = "/etc/pam.d/su"
commented_limits = /^#\s+(session\s+\w+\s+pam_limits\.so)\b/m

ruby_block "add pam_limits to su" do
  block do
    sed = Chef::Util::FileEdit.new(pam_config)
    sed.search_file_replace(commented_limits, '\1')
    sed.write_file
  end
  only_if { ::File.readlines(pam_config).grep(commented_limits).any? }
end if platform_family?('debian')
