Replaces the command window (to list files type dir or ls or ipconfig). Has full support for .net. These can be written in text files, and run (I think the extension is .ps1).
You can start a program…
start notepad
TeamCity
…has the option for a powershell build step (rather than msbuild or nant)
Access the Registry (HKCurrent user)
cd HKCU:
Find running services
get-service
Get-Service | Export-CSV d:\service.csv
Get-Service | Where-Object {$_.status -eq “stopped”} > d:\running-services.txt
Open event logs
show-eventlog
Write .net:
# create the FtpWebRequest and configure it
$ftp = [System.Net.FtpWebRequest]::Create(“ftp://ftp.guardianprofessional.co.uk”)
$ftp = [System.Net.FtpWebRequest]$ftp
$ftp.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile
$ftp.Credentials = new-object System.Net.NetworkCredential(“username”,”password”)
$ftp.UseBinary = $true
$ftp.UsePassive = $true
# read in the file to upload as a byte array
$content = [System.IO.File]::ReadAllBytes(“C:\me.png”)
$ftp.ContentLength = $content.Length
# get the request stream, and write the bytes into it
$rs = $ftp.GetRequestStream()
$rs.Write($content, 0, $content.Length)
# be sure to clean up after ourselves
$rs.Close()
$rs.Dispose()

Powershell to rename
To rename all files in a [tmpfiles] folder, and replace all spaces with a dash…
gci -Path c:\tmpfiles | rename-item -newname {$_.name -replace ” “, “-”}
could also be written
gci | %{rni $_ $_.name.Replace(” “, “-”)}
The shortcuts here are:
gci = Get-Childitem
% = ForEach-Object
rni = Rename-item
| = pipes into next section
To Search for text in a folder
Select-string c:\projects\*\*.aspx -pattern “div”
To find big files
Get-ChildItem -path c:mydata -recurse | where { ($_.Length /1GB) -gt 2 } | foreach { ($_.length/1GB).Tostring(“0.00?) }
Filters:
Get-Process | Where-Object {$_.Name –eq “iexplore”}
