Hi Manoj,

There's a '\n' in your 'host', you have to 'host.chomp' that away.

Your first example should have worked already, but you compared against a String value rather than the host var:
'line.include? "host"' vs 'line.include? host'

Cheers, Torben

sorry Daniel,

Here is the output with Chef log as you advised , as you in logs in bold below it did match but it did not go in the if loop.

hostc=Mixlib::ShellOut.new("hostname -s")

hostc.run_command

host=hostc.stdout

hostp=`hostname -s`

Chef::Log.info " host name is #{hostp} "

puts " hostname is #{host}"

File.open("/local_app/account-rest.properties", "r").each_line do |line|

Chef::Log.info "#{host} Account Rest line: #{line}"

  if line.include?(host)

    Chef::Log.info "Found host #{host} in #{line}"

Thanks Daniel,

but i always get the value of hostname when i run my chef client( even the MixLIb shell out did not fix the issue ) , also i want only the hostname not the fullyqualified hostname so unfortunately i can not use fqdn :( 

hostc=Mixlib::ShellOut.new("hostname -s")

hostc.run_command

host=hostc.stdout

hostp=`hostname -s`

Chef::Log.info " host name is #{hostp} "

puts " hostname is #{host}"

File.open("/local_app/account-rest.properties", "r").each_line do |line|

  puts line

  puts host

   line.chomp

if line.include?(host)

puts " found host #{line}"

Sean brought this up in your previous thread but it’s most likely due to the back ticks being evaluated during the compile phase versus the run phase. Use Chef::Log.info to output debugging information and avoid shelling out in favor of Mixlib::ShellOut. Also, you can get the node hostname through node[:fqdn].

host = node[:fqdn]

Chef::Log.info "Hostname is #{node[:fqdn]}"

File.open("/local_app/account-rest.properties", "r").each_line do |line|

  Chef::Log.debug "#{host} Account Rest line: #{line}"

  if line.include?(host)

    Chef::Log.info "Found host #{host} in #{line}"

    account_value = line.split(':').last

    Chef::Log.info "Found account value #{account_value}"

Hi All,

i have written this code but it never goes in if condition , i ma not sure why , 

if i replace the host with the real value of the hostname -s it does work , i am not sure what the issue is ,

might be a syntax error but Ruby does not complain about it , it silently ignores the if condition

please advise.

host=`hostname -s`

puts " hostname is #{host}"

File.open("/local_app/account-rest.properties", "r").each_line do |line|

  puts line

  puts host

   line.chomp

if line.include? "host"

puts " found host #{line}"

value = line.split(":").last

puts " found account value  #{value}"

puts value

end
