Yes, very weird. You'd get zero if `ls` managed to finish before `close` closed the pipe, but that's not very likely. Or maybe AIX processes in general or AIX's `ls` specifically behave differently when they encounter a closed pipe. Or maybe the shell doesn't relay the death of the child to its parent in AIX. On AIX, what output do you get from `/bin/sh -c 'perl -e'\''kill TERM => $$'\''' ; echo $?` [download]	[reply] [d/l] [select]
