Get-ComputerInfo
Accessing the properties of a command
Get-Computerinfo -Properties csusername Get-Computerinfo -Properties csusername | Get-Member Get-ComputerInfo | Format-List OsType,osName,csusername
Write output to the screen, like Echo
Write-Output "Hello World"
Read Text file
Get-Content filename.txt
Rename-Computer Restart-Computer Get-Date Get-TimeZone
Update Windows From PowerShell
Import csv file The pipe it to another function
import-csv .\filename.csv |
Rename Files using csv list / excel file (exported to CSV)
If you execute the script in the same directory as the files, you don't have to add the full path, but if it's in a different directory the the full path is needed
You can start with an excel file. Header has to be Path and NewName
Path | NewName |
---|---|
cat.jpg | cat01.jpg |
dog.jpg | dog02.jpg |
rat.jpg | rat03.jpg |
Path refers to the Old Filename and NewName is the New Filename
The reason why we add the Path, and NewName is because the Rename-Item function accepts a Path string and a NewName string
import-csv ./rename.csv | rename-item
The CSV File
Path,NewName dog.jpg,222-dog.jpg rat.jpg,333-rat.jpg cat.jpg,111-cat.jpg
Pass txt file to a command
The parentheses is needed to execute that portion first, then pass the content to the Test-Connection
Test-Connection -ComputerName (Get-Content .\filenamewithcomputernames.txt)
Get a Count of Item. Like WC in Linux
Get-ChildItem . -name | Measure-Object
Count : 417 Average : Sum : Maximum : Minimum : Property :
Sorting Object in the pipeline
Get-Process | Sort-Object ID,ProcessName -Unique
