What is the PowerShell equivalent of bash's exec()?

Question

Newbie to PowerShell here. What's the best way to run a new script from within the current process without creating a subshell? In Bash, you would do this via:

source script # Executes the commands in script within the current shell

or

exec script # Same as source, except it completely replaces the current process with script

Is there an equivalent for this in PowerShell?

Answer 1

You can also use .\Script.ps1

Or start typing the name and use TAB to complete the script name.

Dot-sourcing a script allows a function to become available on the command line.

For example:

Function Get-LocalTime { 

$CurTime = Get-Date

"The Date and time currently is $CurTime"

}

Now we dot source (name the above script Example.ps1) PS C:\>. .\Example.ps1

Allowing us to simply type and Tab complete Get-LocalTime

-edit to comment, you can define a function and use the function immediately in the same script. So in Example.ps1, at the last line just enter Get-LocalTime
