Example

method: powershell_execution
params:
  repairedRegex: OPTIONAL_VALUE
  successRegex: OPTIONAL_VALUE
  command: VALUE

Execute either a command, a script or a binary - it supports piping. If the execution succeed, it parses the output as a string. It the output contains the successRegex, it defines a success, else if the output contains the repairRegex, it defines a repair, else it defines an error. successRegex and repairRegex are both optional, but at least one must be defined otherwise the method will always return an error.

Examples:

To return success if process explorer is running, the command parameter needs to be

Get-Process | ForEach { ${const.dollar}_.ProcessName }

as the output of the command is a toString() on the generated objects, so you need to extract the relevant data. And the successRegex needs to be explorer.

Note: the regular expression/string to compare to the output are case insensitive and not anchored.

Note: powershell scripts exiting with a non-zero exit code will always result in an error

Note: the $ need to be escaped, otherwise $_ is evaluated at runtime
