There are workaround for shell which don=E2=80=99t check the pipe status, a= s described in https://unix.stackexchange.com/questions/14270/get-exit-status-of-process-t= hats-piped-to-another (((((exec 3>&- 4>&-; someprog); echo $? >&3) | filter >&4) 3>&1) | (read xs; exit $xs)) 4>&1 but this looks bizarre and you have to do it for every command in the pipe line. --=20 You are receiving this mail because: You are the assignee for the bug.=
