If you want the new record to be in the same line, then you can use awk to do that. or few head and tail commands with line number will help.

I am giving a simple example with awk here,

Code:
user@host> (/home/user/c_test) $
user@host> (/home/user/c_test) $
user@host> (/home/user/c_test) $ cat test.txt
one
two
three
fourth
fifth
sixth

this was similar to your recorddatabase file, i am trying to enter new value instead of three
Code:
xti@host> (/home/user/c_test) $ awk '{if($0~/^three/){system("read -p \"Entre : \" temp;echo $temp")}else {print $0}} ' test.txt >new.txt
Entre : Hello

Now the new.txt file will have new records
Code:
user@host> (/home/user/c_test) $ cat new.txt
one
two
Hello
fourth
fifth
sixth

user@host> (/home/user/c_test) $

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
