As far as I see it, you use the two in distinct cases:
- save alone is exclusively used for copying an image. There is no point in no quitting in this case.
- execution+save is used either to start a server process (hence noquit is desired), or to setup an image (hence, quit is desired). I think favoring the server process is possibly the more common case. On the other hand, you are right in that it is not uniform with respect to the first case, but I think it is not unreasonable.

Do you know why the default behaviour is inverted for that case?

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 ].
