> How do I run a "hello world" program from the command line? You can load and run a smalltalk source file, at the OS command-line, something like — ./pharo Pharo.image st helloworld.st You can pre-load smalltalk source files, save a memory image, and use default startup behavior to run the saved bytecode — ./pharo helloworld.image > deploy that to another machine It's just moving files (VM + bytecode image) so — rsync, ssh

  You can do something like: `Stdio stdout nextPutAll: 'Hello, World!'.`

    Are you suggesting that `FileStream stdout` doesn't work, or that using `Stdio stdout` is in some way better, or that `nextPutAll:` will add a newline, or that … ?

      I think `FileStream` is deprecated in the new version of Pharo.
