Shell腳本函數

1.讀取配置

配置文件：
key=value

#!/bin/bash
declare -A kv_dict=()

function LoadConf()
{
    file_name=$1

    IFS="="
    while read key value 
    do
        kv_dict[$key]=$value
    done < $file_name
}

2.修改文件指定行

參考鏈接

3.自定義shell命令

#!/bin/bash

check_path(){
    str=${1}
    len=${#str}
    let begin=len-1
    tmp=${str:begin:len}
    if [ "${tmp}" == "/" ]
    then
        return 0
    else
        return 1
    fi
}

    check_path ${2}
    ret=$?
    if [ ${ret} -eq 0 ]
    then

    else
