Show a curses based menu selector

whiptail --checklist "Simple checkbox menu" 11 35 5 tag item status repeat tags 1
Not so much handy by itself, but very nice in shell scripts. This makes you a handy ncurses based checklist. Much like terminal installers, just use the arrow keys and hit 'Space' to adjust the selections. Returns all selected tags as strings, with no newline at the end. So, your output will be something like: "one" "two" "three" "four" "etc" For those who prefer bash expansion over gratuitious typing: whiptail --checklist "Simple checkbox menu" 12 35 3 $(echo {one,two,three,four}" '' 0"} ) Things to note: The height must includes the outer border and padding: add 7 to however many items you want to show up at the same time. If the status is 1, it will be selected by default. anything else, will be deselected.
Sample Output
#menu appears as this:
___________________________________
|                                 |
|    [ ] tag     item             |
|    [*] repeat  tags             |
|                                 |
|                                 |
|                                 |
|                                 |
|      <Ok>          <Cancel>     |
|                                 |

What Others Think

Many thanks. Really nice for shell scripts ! And it seems it comes with default install.

Under ubuntu, it is included as part of the default install as well via the 'ubuntu-minimal' package; it is also a recommended dependency of gdm.
