Some additional info: These don't work (they should return the same value, right?):
$ (RANDOM=1; echo $RANDOM) 21465 $ (RANDOM=1; echo $RANDOM) 22374 $ (RANDOM=1; echo $RANDOM) 6444 While all of these do: $ RANDOM=1; echo $RANDOM 16838 $ RANDOM=1; echo $RANDOM 16838 $ RANDOM=1; echo $RANDOM 16838 $ cat bla.sh #!/bin/bash RANDOM=1; echo $RANDOM $ ./bla.sh 16838 $ (./bla.sh) 16838 Ctrl+D (in another terminal) $ RANDOM=1; echo $RANDOM 16838 Is anyone looking into this?
