It doesn't understand cygwin ttys. If you remove the 'tty' from the settings then -t will probably work in a standard cygwin console. It will not work right with applications like 'rxvt' or 'ssh' which use cygwin ptys. There is no workaround for this other than using cygwin's perl. >If there is something more you need to know, then please _tell me what >it is_.

I've noticed that the following one line *application does not display 'is a tty': * *perl -le 'print "is a tty\n" if -t STDIN' * *My cygcheck output is attached as per http://cygwin.com/problems.html ." -- Please use the resources at cygwin.com rather than sending personal email.

Sigh.
I read the FAQ; I found nothing.
I looked in the archives (obvious from my posting).
"Smart questions" (ESR notwithstanding) are in the eye of the beholder.
This is Perl 5.8.0
Windows 2000 Pro
theoretically latest cygwin (I installed it recently)
BASH_VERSION='2.05b.0(1)-release'
CYGWIN='ntsec tty'
If there is something more you need to know, then please _tell me what it is_.
Don't be cryptic.
I've been using Unix since 1983; I've been using cygwin since October 15, 2003.
