Hi, While building busybox-20080618, with defconfig, I stumbled upon a problem with 'ls'. ./busybox ls; echo $? 1 ./busybox ls qwert; echo $? 0 Looks like the status logic is inverted. if (ENABLE_FEATURE_CLEAN_UP) dfree(dnp, nfiles); return (exit_failure == 0); should be return (exit_failure == 1); or return (exit_failure); regards George
