Bash Parse Arrays From Config File

Question

I need to have an array for each \"section\" in the file containing:

[array0]
value1=asdf
value2=jkl

[array1]
value1=1234
value2=5678

I want t

Answer 1

You can declare array in bash scripts with

declare -a =(value1 value2 value 3)

Then you can use them like this

echo ${[index]}

Edit:

Ok, to construct arrays from config file. I would recommend to have a different file for each array you would like to create.

So here are the steps

1.config file (create a file and place your values in it)

100
200
300

2.script file (read values from file and prepare an array)

    array=()

    #setup array
    while IFS=$'\n' read -a config
    do
      array+=(${config})
    done < file_name

    #access values
    echo ${array[0]}
    echo ${array[1]}

IFS denotes the delimiter
-a specifies the array name you want to extract to, so that you can access them inside the while loop.
