Chef Multi line command

I'm trying to write a recipe in Chef but I'm stuck on how I can do a multi line execute into command line in Linux. Firstly is the recipe and following that is the error output I receive. 

node['freeswitch']['source']['dependencies'].each { |d| package d }

execute "apt_update" do
  command "wget -O - https://files.freeswitch.org/repo/deb/debian/freeswitch_archive_g0.pub | apt-key add -&&"
    "echo "deb http://files.freeswitch.org/repo/deb/freeswitch-1.6/ jessie main" > /etc/apt/sources.list.d/freeswitch.list &&"
    "apt-get update &&"
    "apt-get install -y --force-yes freeswitch-video-deps-most &&"

    # because we're in a branch that will go through many rebases it's
    # better to set this one, or you'll get CONFLICTS when pulling (update)
    git config --global pull.rebase true
end

Below is the error output

Here's a recipe that adds the apt repo and installs the package:

# recipes/default.rb

# the package resource can handle multiple packages at once
package node['freeswitch']['source']['dependencies']

# set up a new apt repo, import the key, automatically triggers `apt-get update`
apt_repository "freeswitch" do
  key "https://files.freeswitch.org/repo/deb/debian/freeswitch_archive_g0.pub"
  uri "http://files.freeswitch.org/repo/deb/freeswitch-1.6/"
  components ['main']
  distribution node['lsb']['codename']
end

# finally, install this package. You could even merge the first line with this one.
package "freeswitch-video-deps-most"

You just have to declare the apt cookbook as a dependency in your metadata.rb:

# metadata.rb
name 'whatever'
...

depends "apt"

It's really easy, when you get a bit used to it. Bonus: it's idempotent.

The && is the logical and operator of a shell. Either you explicitly start the command in a shell, like:

execute 'Execute a shell' do
    command "bash -c 'cmd1 && cmd2 && ..'"
end

or you use the bash resource:

bash 'Execute bash script' do
    code <<-EOH
    cmd1 \
    && cmd2 \
    && ... 
    EOH
end

  1. Using 'bash' resource

    bash 'install' do
  user 'root'
  cwd "#{Chef::Config['file_cache_path']}/temp"
  code <<-EOH
     tar -xzvf #{Chef::Config['file_cache_path']}/temp/temp.tgz -C #{Chef::Config['file_cache_path']}/temp
     ./install.sh
  EOH
end

  2. Using 'execute' resource

    execute 'Verification Test' do
  cwd "#{Chef::Config['file_cache_path']}/temp"
  command <<-EOH
    tar -xzvf #{Chef::Config['file_cache_path']}/temp/temp.tgz -C #{Chef::Config['file_cache_path']}/temp
    ./install.sh
  EOH    
  live_stream true
  returns 0
end

Advantage of using 'execute' resource is, we can use 'livestream' property to print the output of the resource commands when chef client runs.
