Interactive script to give user option of what text to add

Hello all,

I have created a script that will remove the first two lines of one text file (body.txt) and then add the text from a different text file (header.txt) directly to the beginning of the freshly modified body.txt file. It is as follows:

Code:

#!/bin/bash

## This script will add a header to the text file generated from the ChemCraft program.  
## Make sure you have modified the header template files to your specific needs!

sed '1,2d' body.txt >tmp && mv tmp body.txt
cat /home/$USER/header.txt body.txt >tmp && mv tmp body.txt

I want to add the option to this script of letting the user choose which header to add. Let us say that there are four possible headers that one could add i.e. head1.txt, head2.txt, head3.txt and head4.txt and that these files are all located in /home/$USER/.

How would I go about modifying my script in such a way to so that the user would be prompted to chose one of these i.e., when they run the script, they get and must choose either the number 1, 2, 3 or 4.

Code:

Please chose the header you want to add:
1. head1.txt
2. head2.txt 
3. head3.txt
4. head4.txt

Once the user has chosen the number, then the script runs and uses the one that they chose, rather than the specific one I have in my file. I would also like it if the only values the numbers 1 through 4 would be accepted.

thanks

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME

       x2sys_merge - Merge an updated COEs tables

SYNOPSIS

       x2sys_merge -Amain_COElist.d -Mnew_COElist.d

DESCRIPTION

       x2sys_merge  will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
       file should only contain updated COEs relatively to the first one.  That is, it MUST NOT contain any new  two  tracks  intersections  (This
       point  is  NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
       to recompute only the COEs between the edited files and the rest of the database.

       -A     Specify the file main_COElist.d with the main crossover error data base.

       -M     Specify the file new_COElist.d with the newly computed crossover error data base.

OPTIONS

       No space between the option flag and the associated arguments.

       EXAMPLES
	      To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try

	      x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
