Rene Paul,

Try this. Example command line from MacOS.

~/Pharo/vms/120-x64/Pharo.app/Contents/MacOS/Pharo --headless pharo12.image eval 1000 factorial

Replace ~/Pharo/vms/120-x64/Pharo.app/Contents/MacOS/Pharo by the path to the VM you like to use.
Replace pharo12.image by the path to the image you like to use.

It will output:

Ciao,
Koen

Hi - the following is a bit old but might still work (and I plan on revisiting it myself) - but my poor man's Pharo build system does the following (note the | tee which I use to capture any load errors that I can grep and cause a build failure). This might be the kind of thing you are looking for - or as others have said you can run headless.

echo -e "\e[1m\nLoading project packages...\e[0m"
pharo Pharo.image --no-default-preferences --save --quit st settings.st loadProject.st config.st
"{'$PROJECT_NAME'. '$DOMAIN_LOGIN'}" 2>&1 | tee LoadProject.log

echo -e "\e[1m\nVerifying project load history...\e[0m"
if (grep -f ../scripts/errorPatterns.txt LoadProject.log | grep -v -f ../scripts/errorPatternsIgnored.txt); then
echo -e "\e[91m\nERRORS detected in package load!\e[0m";
exit 1;
fi

What stops you copy and paste?

Using ANSI Smalltalk, you'd do
[:stream | stream print: 1000 factorial; cr; close] value:
(FileStream write: 'factorial.txt'.
Pharo has never provided an ANSI-compatible FileStream class, which is
a pain for
trying to write portable code.  In Pharo you have to write
'factorial.txt' asFileReference writeStreamDo: [:stream | stream
print: 1000 factorial; cr].

In Pharo 9, you'd have to change #write: to #newFileNamed:.
I wanted to check this in Pharo 12, but PharoLauncher has stopped working.
