Yes, I was a long time ATTer, where the ksh was invented. Quit top-posting, and http://cygwin.com/acronyms/#YSHFRTT The OP already made it clear that changing /etc/password was not what he meant (that only changes your interactive shell), rather he was asking how to make /bin/sh be pdksh instead of bash (for all scripts, so that an arbitrary script ./foo can use pdksh features). If a shell script starts with a #! line, then that's the shell that will be used, regardless of the user's /etc/passwd shell or the current setting of $SHELL. And if a shell script does not start with a #! line, then it will be executed with /bin/sh, again regardless of /etc/passwd or $SHELL. So the only way to change the equation is to change /bin/sh, or to use an appropriate #! line in all affected scripts. Personally, I find #! the more robust option (just like I recommend that you should use #!/bin/bash if you intend on using a bash feature, rather than blindly relying on the fact that /bin/sh defaults to bash in cygwin). -- Eric Blake ebl...@redhat.com+1-801-349-2682 Libvirt virtualization library http://libvirt.org -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Ah, so you mean how to change /bin/sh to be pdksh instead of bash. Simple:
cp /bin/{pdk,}sh
But be prepared to redo that every time you upgrade bash via setup.exe,
and don't come crying to the list if things break that were expecting
bash when they got pdksh.
I did not realize I was commandeering the thread. My apologies - it won't

Merely changing a Subject: line does not change the In-Reply-To: headers
that form threading.

Thanks. I was hoping to effect the change environmentally - not
have to change exe's.
Should I follow that route, no crying will ensue.
I will probably just continue using the shebang line for safety.
