像这样：

#!/bin/bash

onoff=off # all unset by defaul
dialog1(){ dialog --output-fd 1 --extra-button --extra-label "Select All" --checklist "Select options:" 0 0 0 "$@"; }
dialog2(){ choices=$(dialog1 "${options[@]}"); }

set_options(){ # make options array dynamic
    options=(
        1 "Option 1" $onoff
        2 "Option 2" $onoff
        3 "Option 3" $onoff
        4 "Option 4" $onoff
    )
}

set_option
dialog2

case $? in          # if 'Select All' presssed
     3) onoff=on    # set all to on
        set_options # reassemble options
        dialog2;;   # and run dialog again
esac

clear
echo $choices
