??? top in console does not report all programs. "ps aux|less" may be better. Besides "mem" in top is slightly less than physical memory since it is memory size of user spacke program if I remember correctly. physical ram space = kernel + user -- ~\^o^/~~~ ~\^.^/~~~ ~\^*^/~~~ ~\^_^/~~~ ~\^+^/~~~ ~\^:^/~~~ ~\^v^/~~~ + Osamu Aoki <[EMAIL PROTECTED]>, GnuPG-key: 1024D/D5DE453D + + My debian quick-reference, http://qref.sourceforge.net/quick/ +
