Frankly, `ls /proc/[0-9]/fd/ \| wc -l` would be my\r\nexpedient. \r\n\r\n Otherwise, I'd suggest `lsof`, either as an OS call, or\r\npulling apart the sources to see where it's grabbing its\r\ninformation. \r\n\r\n Remember that `/proc` is system state, and that file\r\noperations on /proc may be the preferred operational method. \r\n --\r\n Karsten M.

Post #74,534 by admin 1/14/03 8:31:20 PM Reply	Yabut The alternative is sysctl, which also changes drastically between releases. In fact, the manpage for sysctl specifically says to use /proc instead. Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."

That's for the whole system (I think); I need by process -NT - (admin) - (1) - Jan. 14, 2003, 08:30:36 PM EST
