Smalltalk system: 'abc' Paolo
Thanks shellOut := Smalltalk system: 'sleep 5 && ls -l /etc && sleep 10'. Transcript showCr: shellOut printString. That worked a treat. Is there anything one should be aware of when choosing between the two ways of calling shell commands? The system: call above appeals since it is synchronous and provides the shell output, but just wondering if there is a situation when it is better to use the "Filestream popen: dir" command. And is there a way to get access to the standard error stream? Thank you again Stephen
