You can find the answer to your question in the class comment:

Usage: st [--help] [ --quit ] <FILE>

--help    list this help message

--quit    if specified, the image exits without saving after evaluating FILE

--save    if specified, save the image after evaluating FILE

<FILE>    a file containing valid Pharo expressions

Documentation:

The ST command line handler runs Pharo code stored in a file without quiting.

Example:

pharo Pharo.image st code.st

# By default files ending in .st are recognized and evaluated

pharo Pharo.image code.st

Hi there,

can someone clarify this for me?

lets say you execute in the terminal:

pharo-vm-nox some.image save awesome.image �delete-old

it starts, saves the image and deletes the old one and quits returning control to terminal

but if you do:

pharo-vm-nox some.image ImageBuilder.st save awesome.image �delete-old

it stays forever open

I was taking a look at this but what is �quit� option? can someone explain the behaviour of this please?

STCommandLineHandler>>end
        | quit  |

        quit := self commandLine hasOption: 'quit'.

        (self commandLine hasOption: 'save')
                ifTrue: [ Smalltalk snapshot: true andQuit: quit ].

        quit
                ifTrue: [ self exitSuccess ].
