+function chef-client {
+ <#
+ .SYNOPSIS
+ A chef-client is an agent that runs locally on every node that is under management by Chef.
+ .DESCRIPTION
+ When a chef-client is run, it will perform all of the steps that are required to bring the node into the expected state, including:
+
+ Registering and authenticating the node with the Chef server
+ Building the node object
+ Synchronizing cookbooks
+ Compiling the resource collection by loading each of the required cookbooks, including recipes, attributes, and all other dependencies
+ Taking the appropriate and required actions to configure the node
+ Looking for exceptions and notifications, handling each as required
+ .EXAMPLE
+ chef-client --help
+ #>
+ [CmdletBinding()]
+ param (
+ [parameter(ValueFromRemainingArguments=$true)] $All
+ )
+
+ # Take each input string, escape any \ ' or " character in it and then surround it with "s.
+ # This is to defeat the second-level parsing performed by the MSVCRT argument parser used
+ # by ruby which only understands \ ' and ".
+ #
+ # This is a fuster cluck. Don't touch this unless you are sure you understand regexes.
+ # The \\ is to request a literal \ match in a regex.
+ # The "" is to inject a literal " character in a PS string surrounded by "s.
+ # The replacement pattern must be '\$1' and not "\$1" because $1 is not a real variable
+ # that needs substituting - it's a capture group that's interpreted by the regex engine.
+ # \ in the replacement pattern does not need to be escaped - it is literally substituted.
