This behavior differs from that of all other Bourne family shells I have tested (bash 2.05, ksh93 2001-07-04, pdksh 5.2.14, zsh 4.0.2, Solaris 7 /usr/bin/sh and /usr/bin/ksh). I noticed this because it breaks the evaluation of several (non-critical) tests in the configure script of gtar 1.13.22. >How-To-Repeat: -------> false cat >>foo <<EOF $? EOF cat foo <------- Returns 0 for FreeBSD sh, 1 for all other shells. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
