ps aux的功能是打印出所有进程
ps是最基本也是最强大的进程查看命令
aux都是参数
a = show processes for all users 显示所有用户的进程u = display the process’s user/owner 显示用户x = also show processes not attached to a terminal 显示无控制终端的进程
在下面即将介绍的axo中
o = 格式，，用户定义的
1) Displaying top 10 CPU_consuming processes: 展示消耗CPU最多的10个进程# ps aux|head -1; ps aux|sort -rn +2|head -10 2) Displaying top 10 memory-consuming processes: 展示消耗内存最多的10个进程# ps aux|head -1; ps aux|sort -rn +3|head
To view custom columns we use the below command[root@server ~]# ps axo stat,euser,ruser,%mem,pid,%cpu,comm
Here stat -> status of the processeuser -> effective userruser -> real user%mem -> percentage of memory utilized by processpid -> process ID%cpu -> percentage of memory utilized by processcomm -> command
To view top 10 memory utilized process process[root@server ~]# ps axo ruser,%mem,comm,pid,euser | sort -nr | head -n 10RUSER %MEM COMMAND PID EUSERroot 0.4 sshd 3189 rootroot 0.4 sshd 2486 rootroot 0.2 master 1194 rootroot 0.1 rsyslogd 2918 rootroot 0.1 ps 3355 rootroot 0.1 login 1217 rootroot 0.1 bash 3191 rootroot 0.1 bash 3080 rootroot 0.1 bash 2488 root
