This should take into account our previous behaviour, the behaviour of other shells and POSIX (with the most recent interpretations).= The effect of expansions and errors in redirections varies depending on what ki= nd of command the redirection is applied to (special builtin, other simple command, subshell, compound command). Different from what I wrote in my previous comment, bash also has a differe= nt error behaviour between true (shell aborts) and /usr/bin/true (shell contin= ues with non-zero exit status). --=20 You are receiving this mail because: You are the assignee for the bug.=
