Hi Denys, (at least newer) coreutils package contain a TIMEOUT command with a slightly different syntax then Busybox. Is this intentional or a bug? What about upstream compatibility? Coreutils: timeout [-s SIGNAL] NUMBER[SUFFIX] PROG [ARGS] NUMBER is SECONDS except with suffix m, h or d Busybox: timeout [-s SIGNAL] [-t SECONDS] PROG [ARGS] -- Harald
