# Done!

In the description of the problem we haven't mentioned the `select` loop.

The `select` loop helps us to organize a user menu. It has almost the same syntax as a `for` loop:

```bash
select answer in elem1 elem2 ... elemN
do
  # statements
done
```

The `select` prints all `elem1..elemN` on the screen with their sequence numbers, after that it prompts the user. Usually it looks like `$?` (`PS3` variable). The answer will save in `answer`. If `answer` is the number between `1..N`, then `statements` will execute and `select` will go to the next iteration — that's because we should use `break` statement.

A working example might look like this:

```bash
#!/bin/bash

PS3="Choose the package manager: "
select ITEM in bower npm gem pip
do
  echo -n "Enter the package name: " && read PACKAGE
  case $ITEM in
    bower) bower install $PACKAGE ;;
    npm)   npm   install $PACKAGE ;;
    gem)   gem   install $PACKAGE ;;
    pip)   pip   install $PACKAGE ;;
  esac
  break # avoid infinite loop
done
```

This example, asks the user what package manager to use. Then, it will ask what package we want to install and finally proceed to install it.

If we run this, we will get:

```
$ ./my_script
1) bower
2) npm
3) gem
4) pip
Choose the package manager: 2
Enter the package name: bash-handbook
<installing bash-handbook>
```

In the next exercise you will take a look at what functions are in bash.
