Exploring Commands: Step-by-Step Exercises | MicrosoftВ® Windows PowerShell(TM) Step By Step (Step By Step (Microsoft))

In this exercise, we explore the use of command-line utilities in Windows PowerShell. You will see that it is as easy to use command-line utilities in the Windows PowerShell as in the CMD interpreter; however, by using such commands in the Windows PowerShell, you gain access to new levels of functionality.

Start Windows PowerShell by using Start | Run | Windows PowerShell. The PowerShell prompt will open by default at the root of your Documents And Settings.
Change to the C:\ root directory by typing cd C:\ inside the PowerShell prompt:
```
 Cd c:\
```
Obtain a listing of all the files in the C:\ root directory by using the dir command:
```
 dir
```
Create a directory off the C:\ root directory by using the md command:
```
 Md mytest
```
Obtain a listing of all files and folders off the root that begin with the letter m:
```
 Dir m*
```
Change the working directory to the PowerShell working directory. You can do this by using the Set-Location command as follows:
```
 Set-location $pshome
```
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"
```
After a few counters have been displayed in the PowerShell window, use the ctrl-c command to break the listing.
Display the current boot configuration by using the bootcfg command:
```
 Bootcfg
```
Change the working directory back to the C:\Mytest directory you created earlier:
```
 set-location c:\mytest
```
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
```
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
```
Print out the current date by using the Get-Date cmdlet. This is shown here:
```
 get-date
```
Clear the screen by using the cls command. This is shown here:
```
 cls
```
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
```
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
```
This concludes the step-by-step exercise. Exit the Windows PowerShell by typing exit and pressing Enter.
