Script to install Sophos Antivirus for Mac

Scripting Forums AppleScript | Mac OS X
#1

I want to install Sophos Antivirus for Mac but I’m not having much luck. I can copy the .app file to Applications but how can I make a sudo command where it pulls the current username and places it in the command below
I need to be able to run this script on tons of computers without typing in the username for the current user.
What command can I do to do that?

sudo /Users//Applications/Sophos\ Installer.app/Contents/MacOS/Sophos\ Installer --install

#2 
tell application "System Events" to set theUser to name of current user

-- or

tell application "System Events"
	set theUsers to name of users -- this lists all human users by their short name
end tell
#3

You can use $USER in your command :

for this line :
sudo /Users//Applications/Sophos\ Installer.app/Contents/MacOS/Sophos\ Installer --install

use this :
sudo /Users/$USER/Applications/Sophos\ Installer.app/Contents/MacOS/Sophos\ Installer --install
