I'm trying to understand why subshell setting will be discard.
Under the subshell:
export UMASK=000 && touch output.file
Then back to the parent shell to output into output.file
But output.file has inherited parent shell's UMASK=007

Unless you have some weird version oftouch, then theUMASKenvironmnent variable will have no effect on the execution oftouch. You could try addingls -al output.fileto the end of your subshell's command to confirm.
