[chef] execute bash command

[Gareth Allen < >]

Hi all,

I've written my first custom resource to remove an omd site,  I'm
trying to include an echo in my execute statement as the application
requires user input.  My provider looks like this:

#----------
action :remove do
  execute "remove-site" do
    command "echo -e 'yes' | /usr/bin/omd rm #{new_resource.site_name}"
    only_if { ::File.directory?("/opt/omd/sites/#{new_resource.site_name}") }
  end
end
#----------

Then my recipe:

#----------
omd_site 'test' do
  action :remove
end
#----------

The chef-client shows the following and succeeds, but the site is
never removed.

- execute echo -e 'yes' | /usr/bin/omd rm test

If I run the command manually everything works as expected.  Below is
the output.

----------
PLEASE NOTE: This action removes all configuration files
             and variable data of the site.

In detail the following steps will be done:
- Stop all processes of the site
- Unmount tmpfs of the site
- Remove tmpfs of the site from fstab
- Remove the system user <SITENAME>
- Remove the system group <SITENAME>
- Remove the site home directory
- Restart the system wide apache daemon

I assume the problem is with the echo statement.  Any ideas?
