When I execute commands in the pdksh shell that should set an exit value, $? is not being set. When I use the bash shell, it is. In pdksh: /c/windevel> grep o regexps oo /c/windevel> echo $? 0 /c/windevel> grep Z regexps /c/windevel> echo $? 0 In bash: /c/windevel> grep o regexps oo /c/windevel> echo $? 0 /c/windevel> grep Z regexps /c/windevel> echo $? 1 Grep is just one command I'm using for demonstration. This is true of all commands I've tried so far. Even when I write my own script and exit 1 from it, $? is zero afterwards, which is really hurting my automation efforts. Oh, and I have to use a ksh-like shell, because the same scripts need to run on an AIX box with ksh and no bash.
