Enough of Examples...What are real world examples...
Example 5
Installing an MSI
2. Created a ps1 file with following commands
$box="TestPC002" #this is the name of your server
$product= [WMICLASS]"\\$box\ROOT\CIMV2:win32_Product"
Write-Host "Installing software on $box"
$product.Install("c:\Users\Desktop\Tools\abc.msi")
Do F5, MSI Installed. Easy isn't it..
Example 6
Event Monitoring
# Powershell script to find Error messages in the System eventlog.
get-EventLog system -newest 2000 where {$_.entryType -match "Error"}
Example 7
Writing to EventLog Using Power Shell
function Write-EventLog
{
param([string]$msg = "Default Message", [string]$type="Information")
$log = New-Object System.Diagnostics.EventLog
$log.set_log("Application")
$log.set_source("PSscript")
$log.WriteEntry($msg,$type)
}
write-eventlog "Testing as function" "Information"
Pipelines
Powershell allow you to combine two or more commands into a single custom command that creates an operation known as a pipeline. When commands are chained together in a pipeline, they pass data to each other as objects.
Example 1
Use the Get-Member Cmdlet to discover what types of objects the get-process Cmdlet returns
get-process get-member
Example 2
$a = Get-ChildItem *.txt
foreach ($file in $a)
{
if ($file.length -gt 10)
{
Write-Host $file.name
}
}
In this example, the results from the Get-ChildItem command are put into the $a variable, which is then used by the foreach loop to iterate through the file information.
