Hi, http://mywiki.wooledge.org/ProcessSubstitution
The above webpage says the following. commandA <(commandB; [commandB's exit code is available here from $?]) [commandB's exit code cannot be obtained from here. $? holds commandA's exit code] But I am wondering if there is a walkaround to deal with errors in <(). The ideal behavior should be that if there is a error in <(), then we should not consider commandA is executed correctly even if its return status is 0. Does anybody have a good solution for this situation? Thanks. -- Regards, Peng
