I spoke too soon. It is working correctly, I think. It is taking *much* longer between updates. It used to display updates once every 'percentage cycle' for setiathome (I would get one update per x.xxxxx% done, and there are typically 9 lines between each run, and eas run inc-ed the % by .1). Now I see one update per full percentage point; the data is obviously being writen to the file more regularly than this, it just isn't seen by tail. I log the output because I run setiathome in the background when the machine comes up, but I want to be able to see its progress. (no, I don't run it as root :) -- David Cross | email: crossd@cs.rpi.edu Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
