why does command line execution gives different result to script execution in powershell

Running the following command in powershell command prompt works as i would expect:

Get-Service "my_service"
*output*
 Status   Name               DisplayName                           
------   ----               -----------                           
Running  my_service          My_SERVICE

However if make a ps1 scritp as follows my output is not what i would expect.

$my_service_check = Get-Service "my_service"
echo "My Service Status: $my_service_check"

*output*
my_service:  System.ServiceProcess.ServiceController

why does the script not return the same output as the command?

It's more to do with where you have the quotation marks in the echo statement.

In your example, $my_service_check is a System.ServiceProcess.ServiceController object- it's not a string that just contains the data you see. You could call methods on it, for example- $my_service_check.Start().

Now if you had 

echo "My Service Status:" $my_service_check

PowerShell is smart enough to realize you want to output the human-readable data in that object- and you get the pretty results.

Because you have

echo "My Service Status: $my_service_check"

PowerShell is displaying the object itself as a string- which is almost never what you actually want.

Using the below script seems to output the results as you want it:

$myService = Get-Service #SERVICE_NAME

Write-Host "My service: " $myService

Pause

Output:

My service: SERVICE_NAME

Press Enter to cotinue...:
