Help for record (2 dimensional array.)
I am going to develop a address book using the shell scripting commands without sed, awk, .... I am thinking to apply the concept of 2 dimenstional array. Can I create a two dimensional array for the insertion/updation/deletion of record in unix. If yes then tell me plz or recommend me some material. If any other solution then also tell me.

Most shells do not have arrays, and those that do, have only one-dimensional arrays.

You can simulate 2-dimensional arrays using eval.

Code:
setv() {
    setv_var=$1
    eval "$setv_var=\$2"
}

_getv() {
    eval "_GETV=\$$1"
    case $# in
        2) eval "$2=\$_GETV" ;;
    esac
}

getv() {
    eval echo "\$$1"
}

Sample run:
Code:
$ setv q_1_2 "Something here"
$ getv q_1_2
Something here
