Bash Select keyword Select keyword can be used for getting input argument in a menu format
Example
Suppose you want the user to select keywords from a menu, we can create a script similar to
#!/usr/bin/env bash
select os in "linux" "windows" "mac"
do
echo "${os}"
break
done
Explanation:
Here select keyword is used to loop through a list of items that will be presented at the command prompt for a user to pick from. Notice the break keyword for breaking out of the loop once the user makes a choice. Otherwise, the loop will be endless!
Results: Upon running this script, a menu of these items will be displayed and the user will be prompted for a selection. Upon selection, the value will be displayed, returning back to command prompt.
>bash select_menu.sh
