How about this one: cmd | perl -lne 'BEGIN{open(O,">>out")||die "open:$!"} print O $1 if (/^\d* (\S*)/)' The longest part of that is the handling of the output file. :) Just curious, what is this for? -- Randomly Generated Tagline: "I don't know if all the people in New England are repressed, but I knew a girl from New Hampshire, now she wasn't repressed, she could do long division with her thighs." - Joe Bob Briggs

Re: [Wlug] VNC performance

by Andy Stewart

HI Brad et al, Definitely get that wallpaper (background) to be some plain, boring, solid color, or it will adversely effect VNC performance unless you have really good network bandwidth. Background gradients really kill the performance in many cases. Once that's done, make sure the server and viewer are speaking the same number of colors. I believe the server defaults to 8 bit color. If the server is run with 24 bit color (for example) and the viewer is only 8 bit color, VNC has to transpose and that can reduce performance. Also, try using a Java enabled browser as a VNC client. Sometimes, it works better than the native vncviewer, but only for 8 bit color situations. This is heavily dependent on the Java implementation. Finally, check the network and make sure you aren't bandwidth limited. I'vve seen VNC takes 500 kb/sec on my cable modem during "compilcated" screen redraws, but then settle back down during more idle periods. If you are bandwidth limited, you might try www.tightvnc.com. I hope this helps. Let us know your results.

RE: [Wlug] VNC performance

FYI: Regedt32 is a slightly uglier RegEdit but includes the ability to change the permissions of certain keys (i.e. driver enum keys etc). Even when logged in administrator (which is probably why you cant change the registry - are you logged in as administrator or similar rights?) certain keys do not have write/delete access. Using regedt32 allows you to change the permission (assume admin rights) of such keys and therefore modify them. I only use regedt32 as a last resort when modify the Windows Registry, otherwise use regedit. --- "Evans, Robert" <Robert.Evans(a)stratus.com> wrote: > Try using a registry editor on Windows: > (Typically in these places on Windows 2000) > C:WINNT egedit.exe > C:WINNTsystem32 egedt32.exe > > Robert N.

Re: [Wlug] VNC performance

by Baris Hasdemir

i have used win as tightvnc server and a linux as a client but only for once. When I connected, the other party told me that her wallpaper has disappeared, and she wanted me to put that back there upon leaving her computer. I also didn't see any wallpapers while I was connected. I thought it may because of tightvnc so didn't touch any setting related with the wallpaper. and when I disconnected from her pc she told that the wallpaper was back. I hadn't meant to do that, I think it is a default setting. (may be in a more recent version of tightvnc server) hope it helps, baris On Mon, 3 Dec 2001 14:35:39 -0500 Brad Noyes <maitre(a)ccs.neu.edu> wrote: > Hi All, > I remember some time ago talking with Andy, and others about VNC performance at a > wlug meeting.

Right click on windows desktop, choose settings->background, then under wallpaper select (None). That disables windows wallpaper. Maybe there's something else.
