    Subshells? Or scripts executed in a new shell? Can you provide a minimal example of this behaviour? Commented Jun 25, 2018 at 4:54

    Possible duplicate of difference between "function foo() {}" and "foo() {}" Commented Jun 25, 2018 at 5:03
  • AFAICT, both bash -c 'foo() { echo bar; }; (foo)' and bash -c 'function foo { echo bar; }; (foo)' work fine, and the linked question's answers do not mention any difference related to export behaviour. (And neither bash -c 'function foo { echo bar; }; bash -c foo' nor bash -c 'foo() { echo bar; }; bash -c foo' work: both fail with foo not being found.) Commented Jun 25, 2018 at 5:04
  • @muru I guess not subshells - in my case the bash script would be sourced by the shell, and then the bash functions executed in the new shell (I guess that's not a subshell). Commented Jun 25, 2018 at 5:09

    @AlexanderMills "in the new shell"? Is that new shell the same that sourced it? Can't you just show what you're doing? Commented Jun 25, 2018 at 5:41
