Linux查看进程内存占用情况以MB为单位进行直观显示【测试成功】

巴韭特锁螺丝 2023-09-18

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 11
PID 0 MB COMMAND
2390 301.926 MB java
2887 120.707 MB opt/py3/bin/python3.6
2842 119 MB opt/py3/bin/python3.6
2873 117.539 MB opt/py3/bin/python3.6
2118 117.258 MB mysqld
2843 115.965 MB opt/py3/bin/python3.6
2504 44.9688 MB app/gogs/gogs
1221 40.5703 MB usr/bin/dockerd
1022 20.9922 MB usr/bin/containerd
1952 17.1953 MB bin/drone-server

3、htop命令

[root@Devlops ~]# yum -y install htop
