ABOUT OBJECTS
Short Description
Provides essential information about objects in Windows PowerShell.
Long Description
Every action you take in Windows PowerShell occurs within the context of
objects. As data moves from one command to the next, it moves as one or
more identifiable objects. An object, then, is a collection of data that
represents an item. An object is made up of three types of data: the
objects type, its methods, and its properties.
Types, Methods, and Properties
The object type tells what kind of object it is. For example, an object
that represents a file is a FileInfo object.
The object methods are actions that you can perform on the object. For
example, FileInfo objects have a CopyTo method that you can use to copy the
file.
Object properties store information about the object. For example, FileInfo
objects have a LastWriteTime property that stores the date and time that
the file was most recently accessed.
When working with objects, you can use their methods and properties in
commands to take action and manage data.
Objects in Pipelines
When commands are combined in a pipeline, they pass information to each
other as objects. When the first command runs, it sends one or more objects
down the pipeline to the second command. The second command receives the
objects from the first command, processes the objects, and then passes new
or revised objects to the next command in the pipeline. This continues
until all commands in the pipeline run.
The following example demonstrates how objects are passed from one command
to the next:
Get-ChildItem C: | where { $_.PsIsContainer -eq $false } | Format-List
The first command Get-ChildItem C: returns a file or directory object for
each item in the root directory of the file system. The file and directory
objects are passed down the pipeline to the second command.
The second command where { $_.PsIsContainer -eq $false } uses the
PsIsContainer property of all file system objects to select only files,
which have a value of False ($false) in their PsIsContainer property.
Folders, which are containers and, thus, have a value of True ($true) in
their PsIsContainer property, are not selected.
The second command passes only the file objects to the third command
Format-List, which displays the file objects in a list.
