根据PID过滤查看进程所有信息
#!/bin/bash
read -p "输入要查询的PID: " P
#筛选第二列等于输入的PID号
n=ps aux | awk '$2~/^'$P'$/ {print $11}' | wc -l
if [ $n -eq 0 ];then
echo "该PID不存在!"
exit
fi
echo "--------------------------------"
echo "进程PID: $P"
echo "进程命令:ps aux | awk '$2~/^'$P'$/ {print $11}'"
echo "进程所属用户:ps aux | awk '$2~/^'$P'$/ {print $1}'"
echo "CPU占用率:ps aux | awk '$2~/^'$P'$/ {print $3}'"
echo "内存占用率:ps aux | awk '$2~/^'$P'$/ {print $4}'"
echo "进程开始运行时间:ps aux | awk '$2~/^'$P'$/ {print $9}'"
echo "进程运行的持续时间:ps aux | awk '$2~/^'$P'$/ {print $10}'"
echo "进程状态:ps aux | awk '$2~/^'$P'$/ {print $8}'"
echo "进程虚拟内存:ps aux | awk '$2~/^'$P'$/ {print $5}'"
echo "进程共享内存:ps aux | awk '$2~/^'$P'$/ {print $6}'"
echo "--------------------------------"
执行结果如下
[root@localhost ~]# sh PID_INFO.sh
输入要查询的PID: 6870
