[SOLVED] Using Kdialog in bash script. How to exit the script if one closes the Kdialog window?

[oshunluvr]

I have a set of Service Menus for Dolphin that use Kdialog for pop-up actions and user input. I noticed when I have a Yes-No dialog box open, if I close it rather than responding Yes or No, the script does not exit - it continues to the next part of the script, which is a password prompt. If I close the password dialog, the script exits.

Obviously, the desired action would be for the script to quit/exit when any Kdailog window is closed.

Anyone know how to make this happen?

Sample from a script:

if [[ $isreadonly = "true" ]]; then
    kdialog --title "READ-ONLY btrfs Subvolume."\
    --yesno "This folder is a READ-ONLY btrfs Subvolume.\n Would you like to change this Read-Only subvolume to Read-Write?"\
    --no-label "Yes, make it Read-Write"\
    --yes-label "No, leave it Read-Only"

#close dialog silently
        if [[ "$?" = 0 ]]; then
            exit 0
        fi
    
    PASSWD="$(kdialog --password "This task requires SUDO access. Enter your password: ")"

#allow cancel to exit cleanly
        if [[ -z "$PASSWD" ]]; then
            kdialog --passivepopup "Info action cancelled" 6
            exit 0
        fi
​
​

So if I launch the command from the service menu and get the "kdailog --yesno..." window as above and close it by clicking on the "X" on the window titlebar, I still get the "kdialog --password..." window. But if I then close the password window, the script exits.

It seems like I should be able to correct the behavior by re-writing this part and reversing the action:

#close dialog silently
        if [[ "$?" = 0 ]]; then
            exit 0
        fi
    ​

OK, this seems to have worked;

#close dialog silently
if [[ "$?" -eq 0 ]]; then
continue
else
exit 0
fi​

Nope. Now it exits all the time even when I choose the action.

EDIT: Oops! I used -eq (equal to) rather than -ne (NOT equal). NOW it works, lol

Just noticed this... in bash or zsh I find the (( )) construct more natural, and so less error prone:

if (( $? == 0 )); then
