How to create a shell script that would create a copy of a file (selected by the user) and copy it to a directory (selected by the user) in Bash?

How to solve this task? > To create a copy of a file. > > - The file should be in your current directory (the name of the file to be given by the user) > - The destination directory name to be given by the user. This is how far I've got: echo "Enter the name of the file:" read filename cp -r /home/$FILE ;; Just to add more info, this is what the full exercise is based on: The script should offer a menu with the following options: 1. To create a backup copy of a script file. > The name of the backup copy should have backup after the name of the script and be date stamped e.g. work3Script_backup_10_11_2015. > It should be saved to your home directory using the Environment Variable for your home directory. > The script should error check that the file exists and is a normal file. If this is not the case then the script should allow the user to re-enter the filename until a valid filename is entered 2. To create a date stamped log file called e.g. log_file_10_11_2015 containing > A list of who is logged into the system > The disk usage and > Your currently running processes. > The file should be saved to an existing directory called log_dir which should be situated off your home directory 3. To create a copy of a file. > The file should be in your current directory (the name of the file to be given by the user) > The destination directory name to be given by the user. > The script should error check that the file exists and is a normal file. If this is not the case then the script should allow the user to re-enter the filename until a valid filename is entered. > The script should check that the destination directory exists. If this is not the case then the script should allow the user to re-enter the destination directory until a valid directory is entered. Here is the menu I created:

#!/bin/bash

while true
do
echo "=============================="
echo            "Menu"
echo "=============================="
echo "Option 1 Backing up files: "
echo "Option 2 Date stamped log file: "
echo "Option 3 Create a copy of a file: "
echo "Option 4 Moving a file to place giving by the user: "
echo "Enter q to quit the menu: "
echo -e "\n"
echo -e "Enter your option: \c"
read answer
case "$answer" in

1) while true ; do
   echo "Enter the file name:"
   read filename
   if [ -f "$filename" ]; then
       echo "The file exists."
       break
   else
       echo "File doesn't exist."
   fi
done

FILE=$(date +"outcome3_backup_%d_%m_%y.sh")
touch /home/robert/$FILE ;;


2)FILE=$(date +"log_file_%d_%m_%y.txt")
  touch /home/robert/log_dir/$FILE

  echo "Users online: " > /home/robert/log_dir/$FILE
  (users) >> /home/robert/log_dir/$FILE


  echo "Running proccesses:" >> /home/robert/log_dir/$FILE
  ps -a >> /home/robert/log_dir/$FILE


  echo "Available disk space:" >> /home/robert/log_dir/$FILE
  df --total -h|head -n 1 >> /home/robert/log_dir/$FILE
  df --total -h|tail -n 1 >> /home/robert/log_dir/$FILE ;;


3) ;;


q) exit ;;
