一、需求背景

    Linux默认top或者ps命令，查看出来占用情况显示单位不友好、不易懂。

二、命令参数

   1、 以MB为单位显示

    ps aux --sort=-%mem | awk '{print $6/1024 " MB", $11}' | head -n 11

   2、 以MB为单位显示，同时显示进程ID

    ps aux --sort=-%mem | awk '{print $2, $6/1024 " MB", $11}' | head -n 11

    [root@Devlops ~]# ps aux --sort=-%mem | awk '{print $2, $6/1024 " MB", $11}' | head -n 11PID 0 MB COMMAND2390 301.926 MB java2887 120.707 MB /opt/py3/bin/python3.62842 119 MB /opt/py3/bin/python3.62873 117.539 MB /opt/py3/bin/python3.62118 117.258 MB mysqld2843 115.965 MB /opt/py3/bin/python3.62504 44.9688 MB /app/gogs/gogs1221 40.5703 MB /usr/bin/dockerd1022 20.9922 MB /usr/bin/containerd1952 17.1953 MB /bin/drone-server

    3、htop命令
