Filesystem Usage

Filesystem usage reporting

(something like UNIX 'du')

function directory-summary($dir=".") {

get-childitem $dir |

% { $f = $_ ;

get-childitem -r $_.FullName |

measure-object -property length -sum |

select @{Name="Name";Expression={$f}},Sum}

}

directory-summary

directory-summary | sort sum

An alternate approach...

gci . |

%{$f=$_; gci -r $_.FullName |

measure-object -property length -sum |

select @{Name="Name"; Expression={$f}},

@{Name="Sum (MB)";

Expression={"{0:N3}" -f ($_.sum / 1MB) }}, Sum } |

sort Sum -desc |

format-table -Property Name,"Sum (MB)", Sum -autosize

Another approach...

function Get-DiskUsage ([string]$path=".") {

$groupedList = Get-ChildItem -Recurse -File $path |

Group-Object directoryName |

select name,@{name='length'; expression={($_.group |

Measure-Object -sum length).sum } }

foreach ($dn in $groupedList) {

New-Object psobject -Property @{ directoryName=$dn.name; length=($groupedList |

where { $_.name -like "$($dn.name)*" } | Measure-Object -Sum length).sum }

}

Get-DiskUage

Another approach...

function du($path=".") {

Get-ChildItem $path |

ForEach-Object {

$file = $_

Get-ChildItem -File -Recurse $_.FullName | Measure-Object -Property length -Sum |

Select-Object -Property @{Name="Name";Expression={$file}},

@{Name="Size(MB)";Expression={[math]::round(($_.Sum / 1MB),2)}} # round 2 decimal places

}

Remote (Different Domain)

Assumes the remote server is reachable from your local computer

To use Get-CimInstance to connect to a remote computer in a different domain you can do something like this...

$CimSession = New-CimSession -ComputerName myRemoteComputer.myOtherDomain -Credential (Get-Credential)

You will be prompted for credentials. Enter username in the format: myOtherDomain\myOtherDomainUserUse -CimSession $CimSession in place of -ComputerName myRemoteComputer in any of the Get-CimInstance examples above....

Get-CimInstance -ClassName Win32_LogicalDisk -CimSession $CimSession

To use Invoke-Command to connect to a remote computer in a different domain you can do something like this...

Invoke-Command -ComputerName myRemoteComputer.myOtherDomain -Credential (Get-Credential) -ScriptBlock {Get-PSDrive -PSProvider Filesystem} | Format-Table -autosize
