One reason we like Linux is because it's so easy to complete common (administration) tasks via the shell or scripting.
But sometimes, we have to work on Windows, and not able to install cygwin.
Luckily, Microsoft provides PowerShell, and it's preinstalled with Win7, Windows Server 2008 R2 and later Windows release.
Power Shell is cool and useful, it's different from Linux's Shell, as it's completely object-oriented.
Common Folder/File Operations
Create a folder
mkdir c:\f1\f2\f3
md c:\f1\f2\f3
New-Item c:\f1\f2\f3 -ItemType directory
rm -r c:\f1\f2\f3
Create a file
New-Item c:\f1\f2\f3 -ItemType file -force -value "hello world"
cat c:\f1\f2\f3
Delete Files
Remove-Item -Recurse -Force .\incubator-blur #like linux rm -rf
Remove-Item c:\scripts\* -include .txt -exclude *test
Extract lines from files
Get first 10 lines as head -10 in linux
Get-Content -Path my.csv -TotalCount 10
Get last 10 lines as tail -10 in Linux
Get-Content -Path my.csv | Select-Object -Last 10
Get-Content -Path my.csv | Select-Object -Index(10)
Get the 10th to 100th lines
Get-Content -Path my.csv | Select-Object -Index(10..100)
Get 10th and 100th lines
Get-Content -Path my.csv | Select-Object -Index(10, 100)
Search recursively for a certain string within files
Get-ChildItem -Recurse -Filter *.log | Select-String Exception
Get-ChildItem -Recurse -Filter *.log | Select-String -CaseSensitive -Pattern Exception
Tail -f in PowerShell
In powershell 3.0 and newer version, powershel supports: -Tail:
Get-Content error.log -Tail 10 -Wait
Get-Content error.log -wait
Get-Content error.log -wait | Where-Object { $_ -match "Exception" }
-match is case-insensitive. -cmath is case-sensitive.
List All Java Files in All Subfolders
gci -Recurse -filter *.java | % { $_.FullName }
Select-String
(select-string -path audit.log -pattern "logon failed").count
Select-String C:\Scripts\Test.lxt -pattern "failure" -context 3,1
Measure-Object
Display the number of characters, words, and lines in the Text.txt file.
get-content C:\test.txt | measure-object -character -line -word
get-childitem | measure-object -property length -minimum -maximum -average
import-csv d:\test\serviceyrs.csv | measure-object -property years -minimum -maximum -average
Find the five processes using the most memory
Get-Process | Sort-Object -Property WS -Descending | Select-Object -First 10
Delete all files within a directory
Remove-Item foldername -Recurse
Rename all .TXT files as .LOG files in the current directory:
Get-Childitem -Path *.txt | rename-item -NewName {$_.name -replace ".txt",".log"}
Miscs
Restart-Computer –Force –ComputerName TARGETMACHINE
Run a script on a remote computer
invoke-command -computername machine1, machine2 -filepath c:\Script\script.ps1
Using Get-WmiObject
List all WMI classes:
Get-WmiObject -List
Get-WmiObject -Class Win32_ComputerSystem
Get-WmiObject -Class Win32_BIOS -ComputerName .
gwmi win32_service -filter "name like 'Oracle%'" | select name
gwmi win32_service -filter "startmode='auto'" | select name,startmode
(gwmi win32_service -filter "name='alerter'").StopService()
