Fri 22 Oct 2021 03:14:17 PM UTC, comment #2: I see, I just did not see the obvious. Now it also works for me! Next time I'll surely consult stackexchange first, cause I think bash bugs are pretty unusual. Thanks though!	Dominik Kummer <domson>
Fri 22 Oct 2021 01:20:14 PM UTC, comment #1: You have to enable that behavior. This is from the man page. The info manual contains similar language. "All other aspects of the shell execution environment are identical be- tween a function and its caller with these exceptions: the DEBUG and RETURN traps (see the description of the trap builtin under SHELL BUILTIN COMMANDS below) are not inherited unless the function has been given the trace attribute (see the description of the declare builtin below) or the -o functrace shell option has been enabled with the set builtin (in which case all functions inherit the DEBUG and RETURN traps), and the ERR trap is not inherited unless the -o errtrace shell option has been enabled."	Chet Ramey <chet>
Wed 20 Oct 2021 10:55:18 PM UTC, original submission: The signals ERR and RETURN are not printed inside a function scope but outside. I need to define a function that writes several filtered environments (declare/shopt/trap) into a file, but ERR and RETURN are always omitted.	Dominik Kummer <domson>
