I am writing a console mode shell scipt.I am trying to read a char in my shell script
test.sh

echo "Enter the word"
read ch
echo $ch

Output
-------
[Unix@myunix ~]$ ./test.sh
Enter the word
Hello wonld^[[D^[[D

Issue: Here u see i miss spelled Hello world as Hello wonld.

I am trying to use left arrow keys to go back to the characted 'n' and change it to 'r'. Here the left arrow keys are pressed 2 times. It is displaying ^[[D instead of going back one character.

Can you pls let me know what changes i need to make to work as i expect.

I am using "GNU bash, version 4.2.39(1)-release"

Thanks and Regards,
Jagadish
