shell脚本常用方法

1.数组循环输出

#!/bin/bash

array=(
0,1,2,3.0
0,11,22,33.0
0,111,222,333.0
0,1111,2222,3333.0
)

for((row=0;row<${array[@]};row++))
do
    echo "${array[rows]}"
    var=`echo "${array[rows]}" | awk -F "," '{printf "%d", $2}'`
    echo $var
done

 2.函数调用及传入参数

#!/bin/bash

str="whatinfo"

function print_info() {
    echo "donothing/"$1
}

print_info $str
