Here's a transcript. x1 is your script, modified to print its pid to make killing it easier, and with the addition of `echo HUP' to the SIGHUP signal handler. I used bash-4.2, bash-4.1.7, and bash-4.1.9. Have you tried opening a bug report with Red Hat? Vendors have been known to make their own changes to a package. $ ./bash /usr/homes/chet/x1 2415 rm: cannot remove `out.log': No such file or directory first loop: HUP 4158 out.log second loop: HUP HUP HUP HUP HUP 4158 out.log $ cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 8) $ ./bash --version GNU bash, version 4.2.8(2)-release (i686-pc-linux-gnu) Copyright (C) 2011 Free Software Foundation, Inc.
