  1. The problem statement, all variables and given/known data:
    I need to create dialog interface for adress book i created a while ago but i don't know how to read info from forms

  2. Relevant commands, code, scripts, algorithms:

#!/bin/bash
knyga="adresu-knyga.txt"

       dialog --ok-label "Submit" \\
      --backtitle "Linux User Managment" \\
      --title "Useradd" \\
      --form "Create a new user" \\
                                    15 50 0 \\
    "Pavarde:" 1 1  "$pavarde"      1 10 10 0 \\
    "Vardas:"    2 1        "$vardas"       2 10 15 0 \\
    "Telefono numeris:"    3 1      "$tel"          3 10 8 0 \\
    "El.pastas:"     4 1    "$pastas"       4 10 40 0 \\
