Question

I am having trouble with my Linux Bash programming and in need of some help; below are the requirements that need to be met, please help Thank you

1. Display the user a nicely structured menu with five items.

2. The first three items will execute a bash utility. You may use the examples in the command_menu sample program in your text.

3. The fourth item should execute a bash utility of your choice, but not one included in the command_menu example

4. The final item should allow the user to exit the program

5. The menu should use a 'case' control structure to make the selection

6. The menu should run inside a control structure (i.e. loop) allowing multiple menu choices until the user chooses to quit.

Explanation / Answer

pause(){

read -p "Press [Enter] key to continue..." fackEnterKey

}

user_confirm(){

e_header "I am a sample script"

seek_confirmation "Do you want to print a success message?"

if is_confirmed; then

e_success "Here is a success message"

else

e_error "You did not ask for a success message"

fi

pause

}

# do something in two()

two(){

echo "two() called"
