readconf.sh

xargs -I{} echo  {} < ./conf.txt

Replace echo with your own script/program

 

Method Two:

a=('1 2 3'  '4 5 6'  '7 8 9')
 
for i in "${a[@]}" ; do
b=($i) #此时b就相当于二维数组里面的一维数组了，然后可以再次遍历
    for j in "${b[@]}"; do
        #do someting
    done
done

The shell script reads the file line by line into a two-dimensional array

#!/bin/bash
unset array
for x in `cat xxx.properties`
{
    #字符串截取：从左至右第一个'='之前的内容
    #echo ${x%%=*}
    #字符串截取：从左至右第一个'='之后的内容
    #echo ${x#*=}
    array[${#array[@]}]="${x%%=*} ${x#*=}"
}

echo ${#array[@]}
echo ${array[@]}
