读取系统运行状态的shell脚本

最近在学习shell，老大让写一个读取系统配置信息的脚本当作练习和工作验收，我就写了这么一个脚本，读取操作系统，内核，网卡，cpu，内存，磁盘等信息，目的是让看的人一眼就能看出这台机子的配置以及目前的运行状况：

#!/bin/bash
    #Get system infomation
    (
    sys_time=$(date +"%Y-%m-%d %k:%M:%S")
    #os_version=$(lsb_release -a | sed -n '/Description/p' | awk -F '[:]' '{print $2}' | sed 's/^[[:space:]]*//')
    os_version=$(cat /etc/issue | grep Linux)
    kernel_release=$(uname -r)
    netcard_num=$(ifconfig -a | grep eth | wc -l)
    echo "[public_info]"
    echo -e "sys_time=$sys_time\t#系统时间"
    echo -e "os_version=$os_version\t#操作系统版本"
    echo -e "kernel-release=$kernel_release\t#内核版本"
    
    #########NETCADE INFOMATION##########
    echo 
    echo "[netcard_info]"
    echo "netcard_num=$netcard_num"
    echo "#网卡名字|IP|MAC|网卡驱动|网卡速率|网卡发送流量(bytes)|网卡接收流量(bytes)|网卡总流量(bytes)"
    for((n=0;n<$netcard_num;n++))
    do
    Receive_byte=$(cat /proc/net/dev | grep eth$n | awk '{print$2}')
    Send_byte=$(cat /proc/net/dev | grep eth$n | awk '{print$10}')
    echo "netcard_$((n+1))=eth$n|\
    $(ifconfig eth$n | grep "inet addr" | awk '{print$2}' | awk -F'[:]' '{print$2}')|\
    $(ifconfig -a | grep eth$n | awk '{print$5}')|\
    $(ethtool eth$n | grep Speed | awk '{print$2}' | sed 's/^[[:space:]]*//')|\
    ${Receive_byte}|\
    ${Send_bytei}|\
    $(($Receive_byte + $Send_byte))"
    done
    
    ##########CPU INFOMATION##############

    cpu_used=$(mpstat | grep all | awk '{print$3}')
    echo
    echo "[cpu_info]"
    echo -e "cpu_model=$cpu_model\t#cpu型号"
    echo -e "cpu_core_num=$cpu_core_num\t#cpu核数"
    echo -e "cpu_phical_count=$cpu_phical_count\t#cpu个数"

    echo "#磁盘总容量(单位M)|已用容量(单位M)|可用流量(单位M)|已用百分比（%）|挂载目录"
    df -Pm | grep / | awk '{print$2"|"$3"|"$4"|"$5"|"$6}'
    exit 0
    ) >system_infomation.txt

运行的结果是这个样子的：
