PowerShell Learning Notes-Pipelines

For the command-line administration tool, piping is an important concept. PowerShell also provides pipeline functionality to connect multiple commands in a single sequence line to achieve some of the more complex tasks.

Output to a CSV or XML file

As a system administrator, often look at some system status, such as: the current process of the system, the operation of services and so on. Although we can view it through the GUI application, it is sometimes necessary to look at the command line to output to a CSV or XML file, and then perform some analysis, comparison, and skills.

"Output to CSV": get-process | Export-csv

Use Notepad to view the output files.

Comparing the results of executing the get-process command in the console, you can see that the information exported to the CSV file is much more than the information displayed on the screen. This is due to limited screen capacity, and PowerShell only displays the most important information on the screen.

Second, transfer to the printer

"Command": get-process | Out-printer

Outputs the command result directly to the default printer.

Because the test system does not have a physical printer installed, the command stores the results directly to the PDF document.

Whether the command can form a meaningful pipeline is a certain rule, and listen to the tell.
