how to remove item from dock using terminal

I saw an earlier post about removing items from docks, and someone's solution was to run the following AppleScript:

tell application "System Events"

set dockPlistFile to property list file "~/Library/Preferences/com.apple.dock.plist"

tell dockPlistFile

tell property list item "persistent-apps"

set appTileItems to value of (every property list item whose value of property list item "tile-data"'s property list item "file-label" is not "app name")

set its value to appTileItems

end tell

end tell

end tell

tell application "Dock" to quit

I'm not sure exactly what I have to change to make this work for Terminal (i.e. remove the Terminal Icon from the dock). Which parts must be changed?
