PowerShell WriteLine - Shell-Bash

Introduction

PowerShell is a powerful scripting language that is used by system administrators for managing and automating Windows-based servers. It comes with a set of built-in cmdlets that can be used for various tasks such as querying system information, managing files, and manipulating the registry.

One of the important cmdlets in PowerShell is the WriteLine cmdlet, which is used to output text to the console. This cmdlet is similar to the Console.WriteLine() method in C# and is used to display messages to the user.

In this article, we will discuss the PowerShell WriteLine cmdlet and how it can be used in Shell and Bash scripts.

Syntax

The syntax for the WriteLine cmdlet is as follows:

Write-Output [-InputObject] <Object> [-NoEnumerate] [-Separator <String>] [-Width <Int32>] [<CommonParameters>]

The -InputObject parameter is mandatory and should contain the message that you want to output to the console. The other parameters are optional and can be used to change the behavior of the cmdlet.

Usage

The WriteLine cmdlet can be used in a PowerShell script by simply calling the cmdlet and passing in the message to be displayed. For example:

Write-Output "Hello, world!"

This will display the message "Hello, world!" to the console.

In a Shell or Bash script, the PowerShell cmdlets can be executed by using the pwsh command. For example:

pwsh -c 'Write-Output "Hello, world!"'

This will run the PowerShell command and display the message "Hello, world!" to the console.

Conclusion

PowerShell is a powerful scripting language that is used for managing and automating Windows-based servers. The WriteLine cmdlet is an important tool that can be used to display messages to the user. In Shell and Bash scripts, the PowerShell cmdlets can be executed by using the pwsh command.
