Has anybody a Berkeley style "sysline" for SUN and for System V.
If yes and s/he is willing to share, I would appreciate a
copy very much.
Thanks in advance

I have several programs that all started their lives by myself digging through ps. I cannot be sure if this is derivitive code since I COULD NOT have written them on my own if I had not had ps as a reference. Also, when I get source, what are my rights then? I am using information that I could not have gotten otherwise and making public code out of it. Any comments? Anybody have a public domain kernel dive model I can use as a reference so that what I write is public? :-) -- Josh Siegel (siegel@hc.dspo.gov) (505) 277-2497 (Home) I'm a mathematician, not a programmer!

(The latter has a few problems: (1) it only does load averages if you have the load average daemon I posted earlier [I will repost it], this requires shared memory; (2) I haven't the faintest what JCPU and PCPU are (I worked from an example w output, not a man page or live code), so what my program does is almost certainly wrong.) Since we are not a source site, none of them are based on UN*X source. (None of them look up the actual arguments to a command, either; I *do* have limits to how far I can mindread the kernel! :-) Unfortunately, none of them are Berkeley sysline, since I don't know what that program does. An example of my status line is: (imagine this on your status line) ------------------------------------------------------------------------------- jove brandon load: 0.78 0.55 0.34 No msgs Thu 04/23 11:11 ------------------------------------------------------------------------------- current program username load average mail date/time (needs avenrun daemon) It also shows sender and subject of new mail as it arrives, and also scans an event file (~/.alarm) and displays messages from it when a time, date/time, or weekday/time matches. It uses terminfo (could use termcap, but the process table/ublock stuff won't work under BSD UN*X anyway, so why bother?). ++Brando -- Brandon S.
