I just tried this, and the only problem I see in 1.21.5 is that the
read builtin overwrites the 'Select Option...' bit, since in fish, the
read builtin displays a full prompt. The way to fix this is to Specify
the 'Select' bit as a the prompt for 'read'. Replace:
echo 'Select Option [1 - 5 or x to Return] :'
tput cup 8 38
read menu
with:
read -p 'echo "Select Option [1 - 5 or x to Return] : "'
Another sidenote: Fish ships with a small utility called 'set_color',
used to set terminal colors. I find it easier to remember 'set_color
--bold --background=green red' than the various tput options to do the
same thing. Using set_color, you could change the prompt to:
read -p 'printf "Select Option [%s1 - 5%s or %sx%s to return]: "
(set_color --bold) (set_color normal) (set_color --bold) (set_color
normal)' menu
