1. 使用 ps 查看系统中运行的进程
bash-3.00# ps -ef | more
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 9ÔÂ28 - 4:18 /etc/init
root 102554 1 0 9ÔÂ28 - 0:02 /usr/dt/bin/dtlogin -daemon

root 168042 204930 0 9ÔÂ28 - 0:00 /usr/sbin/inetd
系统中每个活动进程的内存使用情况，并以一种恰当的方式进行了排序。
bash-3.00# ps gv | head -n 1; ps gv | egrep -v "RSS" | sort +6b -7 -n -r
