Long running tasks display no live output

[dscowan]

Output appears to only show up after the commands all execute. I have an inline script with several commands. Some execute quickly but I see no output until the entire script has executed.

All output and errors is collected and after that printing in one step.
I need to do it because errors come in xml format and i need to cleanup it for better read
I may try to change code for live output, but errors anyway will be collected and printed after all.
And I not sure that simple change will help.
