结合zabbix统计/proc/meminfo文件中的内容

vim memory_status.sh

#!/bin/bash   #脚本解释器说明
MemTotal(){
        awk '/^MemTotal/{print $2}' /proc/meminfo    #打印/proc/meminfo文件中以MemTotal开头行的以空格分割的第二列元素的值,单位为kb

} 
$1   #第一个位置参数，位置参数的值为相应函数名，则会调用相应函数

:wq!

chmod +x memory_status.sh

执行命令：

./memory_status.sh MemTotal   获取 /proc/meminfo 文件中 MemTotal 字段的值
