Add function in Powershell

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

Select allOpen in new window

PS : There is a space after dot.

You can refer the following article for other examples..

No, not clear at all.

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"
}

Select allOpen in new window

Here is how you use it..


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