How to get Linux autocompletion with numbered menu?

I recommend https://github.com/junegunn/fzf, I started to replace all my in-shell menu choices with this GREAT tool.

It has bash support, batteries included.

Create bash script file with .sh extension

touch menutools.sh

Make bash script file executable

chmod +x menutools.sh

Insert bash interpreter to the script

echo '#!/bin/bash' > menutools.sh

Edit your script file with your menu based script

#!/bin/bashecho '*********************************************'echo '*               Menu of Tools               *' echo '*********************************************'echo -e "\n\n"echo "(1) Create file"echo "(2) Copy file"echo "(3) Move file"echo -e "\n\n"echo "Enter your choice: "read userChoiceif [ $userChoice == "1" ]; then  clear;  echo '*********************************************'  echo '*               Menu of Tools               *'   echo '*********************************************'  echo -e "\n\n"  echo -e "************[Creating file]**************\n\n"  echo "(1) Enter name for the file: "  read fileName  touch $fileName  echo "$fileName created successfully." fi

Run the script

./menutools.sh

or

bash menutools.sh
