Tab Complete in Bash Script

[Jibe]

I am trying to have tab completion in user entry in my bash script. I got the basic tab completion, but I only want to to work for text files. I figured out that if I run it in the current shell (i.e. run it with ". script"), it works perfectly. My only problem with this is that the variables need to auto-clear and I don't want the end user to have to type that (this is commissioned for a friend). My current code is:

#!/bin/bash
echo 'Input name of file'
bind 'TAB:dynamic-complete-history'
rm .bash_history2 2>/dev/null
PotentialFiles=$(ls -tr *.txt)
for i in $PotentialFiles ; do
        echo "$i" >> .bash_history2
done
history -c
history -r .bash_history2
compgen -W "$PotentialFiles" FileChosen
read -e FileChosen

Some of it is a little weird, such as the custom history file, but ignore this. This is only a part of a larger script.

Thank you in advance!

It seems that you need to add one of this commands that sets key binding before doing the "bind" command:

set -o vi

set -o emacs

so if you have the code:

#!/bin/bash

set -o vi
echo -n 'Input name of file: '
bind 'TAB:dynamic-complete-history'
rm .bash_history2 2>/dev/null
PotentialFiles="$(ls -tr *.txt)"
for i in $PotentialFiles ; do
        echo "$i" >> .bash_history2
done
ls -1tr *.txt > .bash_history2
history -c
history -r .bash_history2
compgen -W "$PotentialFiles" FileChosen
read -e FileChosen
