Linux Question

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

Answer

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'
    code <<-EOH
    cmd1 \
    && cmd2 \
    && ... 
    EOH
end
