  1. <#
  2. .SYNOPSIS
  3. Search a downloaded Canadian Civil Aircraft Register database for an aircraft registation and if found, return the aircraft manufacturer and model (tab-delimited)
  4.  
  5. .DESCRIPTION
  6. First, create a subdirectory 'C' in this script's parent folder.
  7. Next, download the Canadian Civil Aircraft Register database (see links section), unzip it and move the file carscurr.txt (and optionally the other files as well) to the 'C' folder.
  8. Now run this script with an aircraft registration as its only parameter (see examples section).
  9. The script will first look for the specified registration code in column 1 of the carscurr.txt file.
  10. If a match is found, the manufacturer and model are found in columns 4 and 5.
  11. The script will display a tab-delimited string with the registration, the manufacturer and the aircraft model (<registration><tab><manufacturer><tab><model>).
  12. If the script was started by another PowerShell script, the calling PowerShell script may also read the manufacturer and model from the variables $Manufacturer and $Model, passed on by this script.
  13. 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 and model.
  14. Get-Help './AirRegCCmd.ps1' -Examples will show 2 examples of this script being called by another script.
  15. The script contains a "second" script in a comment block, showing the "official' way to deal with the database's CSV files; however, the method used, regular expressions on plain text files, is about 4 times faster.
  16.  
  17. .PARAMETER Registration
  18. A valid Canadian aircraft registration, i.e. C-xxx or C-xxxx (where each x is a single alphanumeric character/digit)
  19.  
  20. .PARAMETER Quiet
  21. Ignore all errors and do not display any error messages; in case of errors, just terminate with return code 1.
  22.  
  23. .PARAMETER Help
  24. Show the script's help screen
  25.  
  26. .PARAMETER Debug
  27. Show some progress messages
  28.  
  29. .OUTPUTS
  30. A tab-delimited string <registration><tab><manufacturer><tab><model> and manufacturer and model are also stored in output variables $Manufacturer and $Model.
  31.  
  32. .EXAMPLE
  33. . ./AirRegCCmd.ps1 "C-AHA"
  34. Will return tab-delimited string "N1944S<tab>BOEING<tab>E75N1", and set variables $Manufacturer to "BOEING" and $Model to "E75N1"
  35.  
  36. .EXAMPLE
  37. "C-AHA" | . ./AirRegCCmd.ps1
  38. Will also return tab-delimited string "N1944S<tab>BOEING<tab>E75N1", and set variables $Manufacturer to "BOEING" and $Model to "E75N1"
  39.  
  40. .EXAMPLE
  41. . ./AirRegCCmd.ps1 "C-AHA" -Debug
  42. This will return:
  43.  
  44. Start searching AHA in carscurr.txt file at <date> <time>
  45. C-AHA   Boeing  E75N1
  46.  
  47. Finished at <date> <time> (elapsed time <time elapsed>)
  48.  
  49. .EXAMPLE
  50. Create and run the following PowerShell script:
  51. ===============================================================
  52. $Registration = 'C-AHA' ; $Manufacturer = '' ; $Model = ''
  53. [void] ( . "$PSScriptRoot\AirRegCCmd.ps1" -Registration $Registration )
  54. Write-Host ( "Registration : {0}`nManufacturer : {1}`nModel        : {2}" -f $Registration, $Manufacturer, $Model )
  55. ===============================================================
  56.  
  57. Besides setting variables $Manufacturer to "BOEING" and $Model to "E75", it will return:
  58.  
  59. Registration : C-AHA
  60. Manufacturer : BOEING
  61. Model        : E75N1
  62.  
  63. .EXAMPLE
  64. Create and run the following batch file:
  65. ===============================================================
  66. REM Note that there should only be a TAB and nothing else between delims= and the doublequote
  67. FOR /F "tokens=1-3 delims=	" %%A IN ('powershell . ./AirRegCCmd.ps1 C-AHA') DO (
  68. 	ECHO Registration : %%A
  69. 	ECHO Manufacturer : %%B
  70. 	ECHO Model        : %%C
  71. )
  72. ===============================================================
  73.  
  74. It will return:
  75.  
  76. Registration : C-AHA
  77. Manufacturer : BOEING
  78. Model        : E75N1
