I've never known 'echo' to wait for input, and haven't heard of this echo &
pub combination. Do you have some link to a tutorial showing how they are
used?
However just wildly guessing, are you wanting to get output from a long
running command without blocking the Pharo UI?
In that case, what about...
[ *stringVar := (PipeableOSProcess command: 'echo...') output ] fork. *
*?*
