Problem
You want to know the location of the currently running script.
Solution
To determine the location of the currently executing script, use this function:
function GetScriptPath
{
SplitPath $myInvocation.ScriptName
}
Discussion
Once we know the full path to a script, the SplitPath cmdlet makes it easy to determine its location. Its sibling, the JoinPath cmdlet, makes it easy to form new paths from their components as well.
By accessing the $myInvocation.ScriptName variable in a function, we drastically simplify the logic it takes to determine the location of the currently running script.
