This tutorial will introduce to you inside out how setting Powershell PATH environment variables should be done. Let’s jump right in for further helpful information!
What Is Windows PATH Environment Variable?
The Windows PATH environment variable is a place to assist applications seeking executables. That means it has the power to either break or the installation of a system or tool.
For example, a path of a specific file could be C:\demo\subfolder1\TestFile_11.txt. This path comprises the following if you divide it into its component parts:
- C: The drive, the qualifier, or the designated path. The portion of the path leading from the left up to the colon (:) character is known as the qualifier.
- \demo\subfolder1\: The folder and any associated subfolders or containers are collectively referred to as \demo\subfolder1\.
- TestFile 11.txt: The leaf’s filename is TestFile 11.txt. As such, the final component or piece of a route is the leaf.
The PATH variable may be managed by administrators using PowerShell, which requires string manipulation.
How To Set Powershell PATH environment variables?
Employing The [Environment] Method
Utilizing the [Environment] variable, which makes use of the fundamental components of the.NET framework, is an alternate method for changing PATH environment variables.
Keep in mind that doing this will permanently alter the PATH environment variables. Throughout all scripting contexts, it will remain persistent.
You may use the below syntax to modify the PATH environment variable.
[Environment]::SetEnvironmentVariable("PATH", $Env:PATH + ";C:\Program Files\Scripts", [EnvironmentVariableTarget]::Machine)
In the syntax provided, there are three parameters for the function [Environment]::SetEnvironmentVariable. The list includes:
- PATH is the kind of environment variable that has to be changed in this situation.
- The environment variable’s new value.
- The environment variable target provided the environment variable’s position. (Level of the Machine, User, or Process)
As such, adopting Write-Output to get the $Env:PATH output now will display the previous PATH environment variable. To update and view the outcome, close your current PowerShell window and open a new one.
Utilizing The $Env:PATH
The PATH variable may often be set by heading to the operating system’s control panel. The $Env:PATH environment variable, on the other hand, allows us to output all of our file paths within Windows PowerShell.
C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Program Files\Common Files\Microsoft Shared\Microsoft Online Services;C:\Windows\System32\WindowsPowerShell\v1.0\
Additionally, we’ll set our PowerShell PATH environment variables using $Env:PATH. Execute the code snippet below to make a backup of your current PATH variable before you begin.
$Env:PATH += ";C:\Program Files\Scripts"
Don’t fail to include the addition (+) operator to attach the value to the variable as well as the semicolon (;), which serves as a separator between your file locations.
You can introduce your own path at the beginning using the following syntax in case you wish it to be called first before the predetermined pathways.
$Env:PATH = "C:\Program Files\Scripts;$Env:PATH"
The PATH environment variable in a PowerShell session will only be momentarily altered by using the $Env:PATH variable. We may employ the technique below to permanently alter the value of our PATH environment variable.
That way, the PATH environment variable will return to its predetermined state when the PowerShell window is closed.
Above is all that could be provided regarding setting Powershell PATH environment variables. Hopefully, this article will work wonders for your coding anyhow. See then!
