What is the command that would let me perform this? I need to way for the User to press ENTER, not a silly Y/N. (It's for general accomplishment actually haha).

Your code will work as is.

The script will wait until the user presses ENTER. You might add an -s option to prevent any other characters being echoed to the screen, and you don't need a variable name since you aren't going to check it:

Code:
read -sp "Press ENTER to go back to menu"
echo "Thank you!"

NAME
run - run an executable SYNOPSIS
run [ -s] [-e] [-n] [-t string] program DESCRIPTION
The run command runs program, using the PATH variable to find it. By default, when program has completed, the user is prompted (Press ENTER to continue:), before being returned to FMLI. The argument program is a system executable followed by its options (if any). OPTIONS
The following options are supported: -e If -e is specified, the user will be prompted before returning to FMLI only if there is an error condition -n If -n is specified, the user will never be prompted before returning to FMLI (useful for programs like vi, in which the user must do some specific action to exit in the first place). -s The -s option means "silent", implying that the screen will not have to be repainted when program has completed. Note that the -s option should only be used when program does not write to the terminal. In addition, when -s is used, program cannot be interrupted, even if it recognizes interrupts. -tstring If -t is specified, string is the name this process will have in the pop-up menu generated by the frm-list command. This feature requires the executable facesuspend (see face(1)) to suspend the process and return to the FMLI appli- cation. EXAMPLES
Example 1: Sample output of run command Here is a menu that uses run: menu="Edit special System files" name="Password file" action=`run -e vi /etc/passwd` name="Group file" action=`run -e vi /etc/group` name="My .profile" action=`run -n vi $HOME/.profile` ATTRIBUTES
