I have requirement to create tab delimited file with values coming from variables.
File will contain only two columns separated by tab.
Header will be added once.
Values will be keep adding upon the script run.
If values already exists then values will be replaced.
I have done so far below work:
Above piece of code:
Will read node.xml file. Look for props. assign variables as below:
e.g.,
There are multiple Nodes in nodes folder so for loop to take care.
Currently I'm able to write values into output file node.txt
Problems:
First time script will run ok. File will be perfect.
But Next time on run Header will be added again and if the folder contains same node names those will be added.
If I use only ">" method with echo then only last node will be added, ignoring the others.
Header method I used to add always print
upon run. I couldn't figure out why.
Is there any other method to add header in tab delimited style.
Shall use sed or awk instead of echo to make output file?
Replace the existing entries.
Help needed to make it working as per needs.
Thanks,

KNIFE-NODE(1) Chef Manual KNIFE-NODE(1)NAME
knife-node - Manage the hosts in your infrastructure
SYNOPSIS
knife node sub-command (options)
DESCRIPTION
Nodes are data structures that represent hosts configured with Chef. Nodes have a name, a String that uniquely identifies the node,
attributes, a nested Hash of properties that describe how the host should be configured, a chef_environment, a String representing the
environment to which the node belongs, and a run_list, an ordered list of recipes or roles that chef-client should apply when configuring a
host.
When a host communicates with a Chef Server, it authenticates using its node_name for identification and signs its reqests with a private
key. The Server validates the request by looking up a client object with a name identical to the node_name submitted with the request and
verifes the signature using the public key for that client object. NOTE that the client is a different object in the system. It is associ-
ated with a node by virtue of having a matching name.
By default chef-client(8) will create a node using the FQDN of the host for the node name, though this may be overridden by configuration
settings.
NODE SUB-COMMANDS
The following node subcommands are available:
BULK DELETE
knife node bulk delete regex (options)
Deletes nodes for which the name matches the regular expression regex on the Chef Server. The regular expression should be given in quotes,
and should not be surrounded with forward slashes (as is typical of regular expression literals in scripting languages).
CREATE
knife node create name (options)
Create a new node. Unless the --disable-editing option is given, an empty node object will be created and displayed in your text editor. If
the editor exits with a successful exit status, the node data will be posted to the Chef Server to create the node.
DELETE
knife node delete name (options)
Deletes the node identified by name on the Chef Server.
EDIT
knife node edit name (options)
-a, --all
Display all node data in the editor. By default, default, override, and automatic attributes are not shown.
Edit the node identified by name. Like knife node create, the node will be displayed in your text editor unless the -n option is present.
FROM FILE
knife node from file file (options)
Create a node from a JSON format file.
LIST
knife node list (options)
-w, --with-uri
Show corresponding URIs
List all nodes.
RUN_LIST ADD
knife node run_list add name run list item (options)
-a, --after ITEM
Place the ENTRY in the run list after ITEM
Add the run list item to the node's run_list. See Run list
RUN_LIST REMOVE
knife node run_list remove node name run list item (options)
Remove the run list item from the node's run_list.
SHOW
knife node show node name (options)
-a, --attribute [ATTR]
Show only one attribute
-r, --run-list
Show only the run list
-F, --format FORMAT
Display the node in a different format.
-m, --medium
Display more, but not all, of the node's data when using the default summary format
Displays the node identified by node name on stdout.
RUN LIST ITEM FORMAT
Run list items may be either roles or recipes. When adding a role to a run list, the correct syntax is "role[ROLE_NAME]"
When adding a recipe to a run list, there are several valid formats:
Fully Qualified Format
"recipe[COOKBOOK::RECIPE_NAME]", for example, "recipe[chef::client]"
Cookbook Recipe Format
For brevity, the recipe part of the fully qualified format may be omitted, and recipes specified as "COOKBOOK::RECIPE_NAME", e.g.,
"chef::client"
Default Recipe Format
When adding the default recipe of a cookbook to a run list, the recipe name may be omitted as well, e.g., "chef::default" may be
written as just "chef"
