PowerShell switch case call function

Code below collect user input and uses switch case statement to check if the input matches, and if it matches a function is called that will execute commands.

Here’s the code:

#get or read from user input

$computer_name = read-host ("Enter Computer Name:") 

switch ($computer_name ) 

{ 

 #if the input is computer_1 then function func_comuputer1 is called

 computer_1    {func_computer1} 

 computer_2    {func_computer2} 

}  

#function called if computer_1 is the input

function func_computer1 { 

write-host "You entered Computer_1"

#or replaced with other function like reboot / shutdown /or other commands

#Restart-Computer -ComputerName computer_1 

}
 

#function called if computer_2 is the input

function func_computer2 { 

write-host "You entered Computer_2"

#or replaced with other function like reboot / shutdown /or other commands

#Ex: Enter-Pssession computer_2 

}



Code below will keep asking for input and will only exit if a specific string matches to exit the script.

Here’s the code: 

 do {

  $computer_name = read-host ("Enter Computer Name:")

  write-host "Enter exit_computer to exit."

 switch ($computer_name ) 

{ 

 computer_1    {func_computer1} 

 computer_2    {func_computer2} 

 }

  #keep asking for computer name until user entered exit_computer

} until ($computer_name -eq "exit_computer")

  

function func_computer1 { 

write-host "You entered Computer_1"

#or replaced with other function like reboot / shutdown /or other commands

#Restart-Computer -ComputerName computer_1 

}

function func_computer2 { 

write-host "You entered Computer_2"

#or replaced with other function like reboot / shutdown /or other commands

#Ex: Enter-Pssession computer_2 

}


Cheers..till next time!

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.

So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out.

Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data.
