I've noticed some really strange behaviour with pipes. Try this: mkfifo wow cat < wow & cat < wow & echo hi there > wow If I run this in an rxvt, using tcsh, my window disappears after the echo command! Works ok if you only run one cat. My kernel is 2.2.12. Can anyone explain? Cheers Hamish -- Hamish Moffatt VK3SB. CCs of replies on mailing lists are welcome.
