I'm running the latest development release. Tasklist appears to be WMI heavy. I ran Process Monitor and it appears that when running tasklist /m under bash, WMI is significantly more active. WMI actually opens tzres.dll (Time Zone Resources) about 150,000 times vice a mere 800 times when executing through a standard command prompt. Moreover, WMI really doesn't appear to be doing much of anything with tzres.dll... just open/close/open/close/open/close. Very curious indeed. -- 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

RE: Running tasklist /m in cygwin hangs
Hi, Running "tasklist /m file.dll" hangs in Cygwin even though it works perfectly fine in the cmd window. Is there any reason for this? I am using a somewhat older cygwin (1.7.25) on a Windows 7 box, and do not want to upgrade unless newer cygwin doesnt show the problem.
