Hi Stef,

I'm not sure what you mean by "using Squeak to script", but did you
have in mind something like the following in CommandShell:

script: aScriptString onFailureDo: aBlockWithOneParameter
  "A script is a String containing a list of commands separated
  by Character cr. Evaluate each command in aScriptString until
  a failure is encountered. On failure, answer the result of
  evaluating aBlockWithOneParameter with the last proxy to have
  been evaluated as its parameter. Otherwise, answer the last
  process proxy to have been evaluated."

  "CommandShell new open; 
    script: 'who
        help
        ls -l NOSUCHFILE
        help'
    onFailureDo: [:p | 'the proxy that failed was ', p printString]"
