You can instead of
rm -f redo-afn2-dev.out; ./redo.sh afn2-dev & jobs -x tail --pid %./redo.sh -F
-n +0 redo-afn2-dev.out
Type
h=afn2-dev; rm -f redo-$h.out; ./redo.sh $h & jobs -x tail --pid %./redo.sh -F
-n +0 redo-$h.out
Then, when you need change hostname you find this command and just change h=
