  1. <#
  2. .SYNOPSIS
  3. Search the online Icelandic aircraft registration database for an Icelandic aircraft registation and if found, return the aircraft manufacturer and model (tab-delimited)
  4.  
  5. .DESCRIPTION
  6. Run this script with an aircraft registration as its only parameter (see examples section).
  7. The script will try to find the registration in the online Icelandic aircraft registry.
  8. If a match is found, the script will display a tab-delimited string with the registration and the manufacturer/model (<registration><tab><tab><manufacturer_and_model>).
  9. If the script was started by another PowerShell script, the calling PowerShell script may also read the manufacturer/model from the variable $Manufacturer, passed on by this script.
  10. If the script was started by a batch file, the calling batch file can use 'FOR /F' on this PowerShell script's screen output to find the manufacturer/model.
  11. Get-Help './AirRegPHCmd.ps1' -Examples will show 2 examples of this script being called by another script.
  12.  
  13. .PARAMETER Registration
  14. A valid Icelandic aircraft registration, i.e. TF-xxx (where each x is a single letter)
  15.  
  16. .PARAMETER Quiet
  17. Ignore all errors and do not display any error messages; in case of errors, just terminate with return code 1
  18.  
  19. .PARAMETER Help
  20. Show the script's help screen
  21.  
  22. .PARAMETER Debug
  23. Show some progress messages
  24.  
  25. .OUTPUTS
  26. A tab-delimited string with <registration><tab><manufacturer_and_model>, and a variable $Model set to manufacturer AND model
  27.  
  28. .EXAMPLE
  29. . ./AirRegTFmd.ps1 "TF-NPK"
  30. Will return tab-delimited string "TF-NPK<tab>Douglas C47A" and set variable $Model to "Douglas C47A"
  31.  
  32. .EXAMPLE
  33. "TF-NPK" | . ./AirRegTFCmd.ps1
  34. Will also return tab-delimited string "TF-NPK<tab>Douglas C47A" and set variable $Model to "Douglas C47A"
  35.  
  36. .EXAMPLE
  37. Create and run the following PowerShell script:
  38. ===============================================================
  39. $Registration = 'TF-NPK' ; $Model = ''
  40. [void] ( . "$PSScriptRoot\AirRegTFCmd.ps1" -Registration $Registration )
  41. Write-Host ( "Registration : {0}`nModel        : {1}" -f $Registration, $Model )
  42. ===============================================================
  43.  
  44. Besides setting variable $Model to "Douglas C47A", it will return:
  45.  
  46. Registration : TF-NPK
  47. Model        : Douglas C47A
  48.  
  49. .EXAMPLE
  50. Create and run the following batch file:
  51. ===============================================================
  52. REM Note that there should only be a TAB and nothing else between delims= and the doublequote
  53. FOR /F "tokens=1-3 delims=	" %%A IN ('powershell . ./AirRegTFCmd.ps1 TF-NPK') DO (
  54. 	ECHO Registration : %%A
  55. 	ECHO Model        : %%B
  56. )
  57. ===============================================================
  58.  
  59. It will return:
  60.  
  61. Registration : TF-NPK
  62. Model        : Douglas C47A
