It is possible to run sift from the command line, this offers several advantages:

• With no need to update a GUI or plots the application will run much faster
• With experience it makes it possible to quickly execute commands
• Creating a bat file it is possible to completely automate processing

To start sift in command line mode, open a command line console, navigate to sifts install directory and run sift with any argument that starts with a single dash (-) if you do not want to run any commands as Sift is launched you can instead pass -NoGUI

• Commands are prefixed with a dash these are considered a reserved character, but Sift will ignore any dashes that are within double quotes so file-name.txt will cause an error, where “file-name.txt” will not.
• Commands and parameters are case insensitive
• any parameters containing a space or a dash (e.g. a folder path) must be wrapped in double quotes (“”)
• Command parameters are named not positional, so the order they are passed does not matter
• Some commands have a default parameter, in these cases the parameter name can be omitted, for example with -loadLib the directory parameter name is optional. so either of the following will work: -loadLib directory “folder path” or -loadLib “folder path”. These parameters are marked as default in the list below
• Commands can be entered all at once in the same command that launches sift, or one at a time
• Enter the command -Help to get a list of all available commands
• Pass the parameter Help to any command to get a list and description of all of its parameters
• To exit pass the command -Exit, or press Ctrl + C to quickly exit at any time (Sift will exit once the current command finishes executing)
• Most commands have one or more aliases that will be accepted

All commands and their parameters are listed below
