I want to use user input of special characters in conditional statement.
I tried:

read -p "press arrow up" foo

if [ $foo == "^[[A" ]; then echo yes; fi

It did not do what I wanted it to do.

In bash, you could use ANSI-C quoting

#!/bin/bash



read -p "press arrow up " foo



if [ "$foo" = $'e[A' ]; then

  echo 'yes'

fi
