Are you *sure* you're using the Cygwin grep? In general, mixing MS SFU and Cygwin in the PATH is not a good idea. Try explicitly using /bin/grep, i.e., Guilty as charged. That was it. Thank you. I did one better and uninstalled MS SFU, which is about what it deserves. Now it works as preditcted. Thank you for the help, and for the clue-by-4 on the diagnostic tool that uncovered the problem. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
pdksh not setting $? with exit status of commands
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. Thanks. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

The closest thread I could find is negative error status: gcc vs. cl, which invloves both negative exit values and Windows commands, neither of which are relevant to my problem. I'm trying to use Cygwin binaries inside Cygwin's pdksh shell, and expecting 0 or 1. If you can recall anything else about the thread you mentioned, I would appreciate it. For what it's worth, the search page will not let me search on $?. I tried searching for ksh exit Thanks for your help. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

You ran grep then echo separated by a ;, while I ran it on two separate lines. These should do the same thing (as it does on my other target, AIX), but it doesn't appear to. When I run your example in my Cygwin pdksh shell, I get the same results as you. It looks like I can use that format as a workaround for the problem, but I sure would like to understand why it doesn't work as expected in my example, when both examples produce the same results in AIX's ksh, so I can predict these kinds of problems in the future better.
