Add function in Powershell

Hi,

I'm new to Powershell, I do know my way around but the basics only.
I found a function which I like to implement.

How do I do this (where do I copy this function and how do I call for it)?

Please advise.

You either have to add the complete path
PS> . c:\powershell\Function.ps1

Open in new window

or if the script is in same path where you run the script then (as you mentioned in your post)
. .\Function.ps1

Open in new window

You can dot source the script.. For example save the function it in to a ps1 file and run it in PowerShell console as shown below. Once it is done. Function saved in the .ps1 file will be available in console..


PS> . c:\powershell\Function.ps1

Open in new window

PS : There is a space after dot.

You can refer the following article for other examples..

I have added the function but then what? If I call for the function I get errors "the term -myscript.ps1" is not recognized as the name of a cmdlet, function, script file ...

I had to add an extra . before the ps1.
My path is that long so I did not use c:\... just the .\myscript.ps1 that doesnt work unless you add an extra .

So that is . .\Myscript.ps1

For example.. if you have following function saved in to a function.ps1 file in C:\temp

Function Test-Echo ($String){
Write-Host "Hello $String"
}

Open in new window


Here is how you use it..

Example
Another option is to just copy and paste the code in to the PowerShell console and then start using the function.
