Question Extraction de donnée de Get-DirStats

Bonjour,

Je pense que vous connaissez le script get-dirstats qui permet de faire une extraction de dossier + taille + nombre de fichier d'un emplacement donnée.

J'aimerais une petite précision si je peux me permettre, Lors de l'extraction de la taille des dossiers, j'aimerais convertir cette donnée en GB, car pour le moment elle est seulement en Octet.

Voici ma ligne de commande :
[code:1].\Get-DirStats.ps1 -Path D:\Projets -FormatNumbers -Total | Export-Csv D:\test.csv -Encoding utf8 -Delimiter \";\" -NoTypeInformation[/code:1]

voici le script :
[code:1]# Get-DirStats.ps1
# Written by Bill Stewart (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.)
# Outputs file system directory statistics.

#requires -version 2

<#
.SYNOPSIS
Outputs file system directory statistics.

.DESCRIPTION
Outputs file system directory statistics (number of files and the sum of all file sizes) for one or more directories.

.PARAMETER Path
Specifies a path to one or more file system directories. Wildcards are not permitted. The default path is the current directory (.).

.PARAMETER LiteralPath
Specifies a path to one or more file system directories. Unlike Path, the value of LiteralPath is used exactly as it is typed.

.PARAMETER Only
Outputs statistics for a directory but not any of its subdirectories.

.PARAMETER Every
Outputs statistics for every directory in the specified path instead of only the first level of directories.

.PARAMETER FormatNumbers
Formats numbers in the output object to include thousands separators.

.PARAMETER Total
Outputs a summary object after all other output that sums all statistics.

Merci de votre futur aide

Bonne soirée à vous

salut tcottin

pour avoir l'affichage en Go il faut divisé le resultat par 1024*1024*1024 ou en plus simple /1GB

il faut aussi que le formats des nombres soit utilisable pour la division, c'est pour ça que j'ai enlevé l'option \"-FormatNumbers\"
[code:1].\Get-DirStats.ps1 -Path i:\temp -Total | select path, files, @{e={$_.size/1GB};n=\"Size(Go)\"} | Export-Csv D:\test.csv -Encoding utf8 -Delimiter \";\" -NoTypeInformation[/code:1]

tu peux rajouter aussi un arrondie, ici à 4 chiffres apres la virgule :
[code:1].\Get-DirStats.ps1 -Path i:\temp -Total | select path, files, @{e={[math]::round($_.size/1GB,4)};n=\"Size(Go)\"} | Export-Csv D:\test.csv -Encoding utf8 -Delimiter \";\" -NoTypeInformation

Merci !!! C'est parfait !

Je me prennais la tête depuis ce matin pour comprendre, je tentais de modifier dans le script, mais je suis pas encore une très grand expert de powershell.

Merci de votre aide, mes compétences augmente encore avec votre Select

Merci, et bonne journée et bon week end.
