I would also like to see this example in the documentation: $ ( echo sub-$BASH_SUBSHELL ); echo main-$BASH_SUBSHELL sub-1 main-0 This example answers all doubts raised in this discussion. It also hints at the fact that: ( echo 'sub-$BASH_SUBSHELL' ) does not work like an inexperienced quoter could wrongly assume.
