You did mention ] HKLM/Software/Cygwin/setup, the "rootdir" value. But you noted that that is in version 1.7. (When mentioning it, by the way, you might also mention REG.exe, a program to do registry access, and the options for FOR that allow running a program and getting the results in a variable in CMD.exe. I hadn't heard of REG until I went searching just now.) -- Tim McDaniel, tmcd@panix.com -- 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/
