Hi,

Code:
 
function amendRecord() {
clear
 
        read -p "Please enter the Staff ID of the record you wish to edit: " strID
        output=$(grep "$strID" recordDatabase)
 
        strID=$(echo $output | cut -d ":" -f1)
        strForename=$(echo $output | cut -d ":" -f2)
        strSurname=$(echo $output | cut -d ":" -f3)

        strTech=$(echo $output | cut -d ":" -f5)
        strComm=$(echo $output | cut -d ":" -f6)
 
                        if [[ -z "$output" ]] ; then
                                echo "You have entered an invalid ID, please try again."
                                sleep 2
                                amendRecord
                        fi
                        if [[ -n "$output" ]] ; then
                                read -p "The record: ($output) is about to be amended.. Press Y to continue or N to cancel: " yesNo
                                        case $yesNo in
                                                [Yy]) echo "Editing Record"
                                                        #EDIT CODE GOES HERE!!! ;;
                                                [Nn]) echo "Cancelling edit.."
                                                      sleep 0.5
                                                      loadWelcomeScreen ;;
                                                *)    echo "You did not press Y or N, please try again.."
                                                      sleep 0.5
                                                      amendRecord ;;
                                        esac
                        fi

NAME
chsh - change your login shell SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username] DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one. chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries. OPTIONS
-s, --shell shell Specify your login shell. -l, --list-shells Print the list of shells listed in /etc/shells and exit. -u, --help Print a usage message and exit. -v, --version Print version information and exit. VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root. EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid. SEE ALSO
login(1), passwd(5), shells(5) AUTHOR
