Thanks a lot for the help Daniel,
it worked , i used node.hostname as you suggested and it provided me the
value i was looking for, Thanks a lot for the help,
its been troubling me from last 3-4 hours now, i am not using Mixlib Shell
out rather i wrote ruby_block and ruby for this, i hope thats the right way
to do it,
all this time this host.chomp was the issue.
Thanks again everyone for the help

If you can’t use node[:fqdn] due to it including the rest of the node’s
hostname then you need to call .chomp on the output from
ShellOut.run_command:
chef > Mixlib::ShellOut.new('hostname -s').run_command.stdout
=> "disrupt\n”
Otherwise you’ll never match that ‘account-rest.properties’ file since it
contains “pdevecsas300:acc1” and not “pdevecsas300\n:acc1”. I’d really
recommend leveraging as much of chef’s helpers like node attributes and
Ruby classes (File, Dir) as possible instead of shelling out. Look at
node.hostname, it may return the result you’re looking for without shelling
out; otherwise, use node.hostname.split(‘.’).first so you just get the
first part of the hostname that’s contained in the file you’re loading.

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}"
end

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
