OK. Thanks, good to know that. -- Still, not sure why I have to export the SHELL var to GNU screen now since in the past several years I have not done this. Recently I stopped using 'putty -ssh localhost' for my terminal, and I'm using 'rxvt' instead, but I can not see why that would matter. In Linux, 'screen' sets up login shells correctly, I use the same ~/.screenrc for both cygwin and linux, and I'm not exporting SHELL to screen in linux. Non cygwin question: what is the best way to tell GNU screen to read /etc/passwd to get SHELL, and start all new screen windows with login shells? -- thanks, Tom -- 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
