Suppose you mostly use the “stop service –name spooler” during your daily work, for ease you can create a short variable for this command and instead of typing whole command you can use that variable to run this command. Remember all the variables are start with $.
$p= service –name spooler
Now you can use the just $p instead of typing the whole command.

PS C:UsersAdministratorDesktop> .users.ps1
