# Working with Files and Folders
|
|
|
|
## Get-Help
|
|
|
|
## Get-Children
|
|
|
|
Gets items in a specified location. To list the folders in my drive C, I will run
|
|
the command below:
|
|
|
|
```
|
|
Get-ChildItem c:\
|
|
```
|
|
|
|
This will list all the top-level folders. To list all files, folders include sub-folders use the `-Recurse` parameter.
|
|
|
|
## Copy-Item and Move-Item
|
|
|
|
You could use the __Get-ChildItem__ Cmdlet to list items in a folder, then pipe
|
|
the result to __Copy-Item__ Cmdlet to copy the items to a new location. The
|
|
command below will do the job:
|
|
|
|
```
|
|
Get-ChildItem C:\Dropbox | Copy-Item -Destination C:\NewFolder
|
|
```
|
|
|
|
The above PowerShell command will only copy the top-level folders and
|
|
files - it will NOT copy sub-folders and files. To copy all files and folders
|
|
including sub-folders, include the -Recurse parameter in the __Get-ChildItem__
|
|
command as shown below:
|
|
|
|
```
|
|
Get-ChildItem C:\Dropbox -Recurse | Copy-Item -Destination C:\NewFolder
|
|
```
|
|
|
|
While the __Copy-Item__ Cmdlet copies items from one location to another the
|
|
__Move-Item__ Cmdlet moves the item.
|
|
|
|
## RemoveItem
|
|
|
|
## NewItem
|
|
|
|
__New-Item__ can be used to create files, folders and registry keys and entries. The command below creates a text
|
|
file called weekly_file.txt in c:\logfiles folder:
|
|
```
|
|
New-Item -Path c:\logfiles -Name weekly_file.tx
|
|
```
|
|
|
|
## RenameItem
|
|
|
|
__Rename-Item__ Cmdlet is used to rename things in Windows. This Cmdlet can
|
|
rename files, folders and registry keys. This command will rename
|
|
weekly_file.txt to monthly_file.txt
|
|
|
|
```
|
|
Rename-Item -Path C:\logfiles\weekly_file.txt -NewName monthly_file.txt
|
|
```
|
|
|
|
## Export-Csv
|
|
|
|
__Export-Csv__ converts a set of string into CSV and saves in a file. This Cmdlet
|
|
is very important in reporting.
|
|
|
|
```
|
|
Get-Command -Verb Export
|
|
```
|
|
|
|
```
|
|
Get-Command -Verb Export | Select-Object CommandType, Name, Version, Source | Export-Csv -
|
|
NoTypeInformation -Path C:\NewFolder\ExportCommands.CSV
|
|
```
|
|
|
|
# Managing Processes
|
|
|
|
## Get-Process
|
|
|
|
This PowerShell Cmdlet lists all the processes running on a local computer. If
|
|
you use the ComputerName parameter, you can display the processes on a
|
|
remote computer.
|
|
|
|
### Start-Process and Stop-Process
|
|
|
|
The __Start-Process__ Cmdlet can start a stopped process while the __Stop-Process__ Cmdlet
|
|
can stop a running process.
|
|
To start a process, pipe the output of __Get-Process__ command to the __Start-Process__ command.
|
|
As an example, to stop a process with ID 10500, use the command below.
|
|
|
|
```
|
|
Get-Process -Id 10500 | Stop-Process
|
|
```
|
|
