== Select Menus ==

A select menu looks like:

{{{
1) /bin           3) /dev          5) /home         7) /lib64        9) /mnt         11) /proc        13) /run         15) /srv         17) /tmp         19) /var
2) /boot          4) /etc          6) /lib          8) /lost+found  10) /opt         12) /root        14) /sbin        16) /sys         18) /usr
#? 
}}}

Note that `#? ` as shown above is the default `$PS3` value.

This menu is printed to `STDERR` and waits for the user to make a selection from that menu.

----



== Usage ==

The above menu was generated with:

{{{
select name in /*; do
  break
done
}}}

The expansion is handled in the same manner as [[Bash/Looping#For_Loops|for loops]]. That includes the implcit default of iterating over `$@`.

The user selection is made available as `$name` in the above example. The 'loop' needs to be explicitly broken.
