PS C:/> get-help get*

PS C:/> get-help getdrive -example

1.Retrieve an alphabetic listing of all currently defined aliases, and inspect the list for one assigned to either the Get-Help cmdlet or the key stroke combination gh. The command to do this is as follows:
get-alias |sort
2.After you have determined that there is no alias for the Get-Help cmdlet, and that none is assigned to the gh key stroke combination, review the syntax for the Set-Alias cmdlet. Use the -full argument to the Get-Help cmdlet. This is shown here:
get-help set-alias -full
3.Use the Set-Alias cmdlet to assign the gh key stroke combination to the Get-Help cmdlet. To do this, use the following command:
set-alias gh get-help

1.Change to the C:/ root directory by typing cd C:/ inside the PowerShell prompt:

Cd c:/
2.Obtain a listing of all the files in the C:/ root directory by using the dir command:

dir
3.Create a directory off the C:/ root directory by using the md command:

Md mytest
4.Obtain a listing of all files and folders off the root that begin with the letter m:

Dir m*
5.Change the working directory to the PowerShell working directory. You can do this by using the Set-Location command as follows:

Set-location $pshome
6.Obtain a listing of memory counters related to the available bytes by using the typeperf command. This command is shown here:

typeperf "/memory/available bytes"
7.After a few counters have been displayed in the PowerShell window, use the ctrl-c command to break the listing.

8.Display the current boot configuration by using the bootcfg command:

Bootcfg
9.Change the working directory back to the C:/Mytest directory you created earlier:

set-location c:/mytest
10.Create a file named Mytestfile.txt in the C:/Mytest directory. Use the fsutil utility, and make the file 1,000 bytes in size. To do this, use the following command:

fsutil file createnew mytestfile.txt 1000
11.Obtain a “directory listing” of all the files in the C:/Mytest directory by using the Get-ChildItem cmdlet. This is shown here:

get-childitem
12.Print out the current date by using the Get-Date cmdlet. This is shown here:

get-date
13.Clear the screen by using the cls command. This is shown here:

cls
14.Print out a listing of all the cmdlets built into Windows PowerShell. To do this, use the Get-Command cmdlet. This is shown here:

get-command
15.Use the Get-Command cmdlet to get the Get-Alias cmdlet. To do this, use the -name argument while supplying Get-Alias as the value for the argument. This is shown here:

get-command -name get-alias
16.This concludes the step-by-step exercise. Exit the Windows PowerShell by typing exit and pressing Enter.
