zenity auto-close instantly closes

Hi all,

I'm trying to make this simple script work. If I remove the zenity auto-close option, the progress bar goes nicely from 100 to 0, and time counts down. But I don't get an exit code to use, and the zenity box stays there.
If I do use the auto-close option, the zenity message instantly disappears without counting down, with an exit code 0.

I would like this to close automatically after timeout (10 minutes, adjustable), with the same exit code as if I would click the "OK" button, and also being able to cancel the automatic shutdown, by clicking "cancel".

Any ideas what I'm doing wrong here?

Thanks in advance!!

code:

Code:

#!/bin/bash



CD=10  # number of minutes before shutdown



CDA=$CD

(

while [ $CDA != 0 ]

do

        echo "# Shutdown? \nAutomatic shutdown in $CDA minutes" 

        BAR=$(($CDA * 100 / $CD))

        echo $BAR ; sleep 60

        (( CDA-- ))

done

) | 

zenity --progress --title="autoshutdown" --auto-close





if [ "$?" = 0 ] ; then

        notify-send 'shutdown cancelled'

else

        shutdown -p now

fi

you certainly don't need the brackets around the while loop, you can put the pipe right behind 'done'.

i just tried this, and it's working as desired:

Code:

$ i=0;while sleep 1; do echo $((i++)); done | zenity --progress --title="autoshutdown" --auto-close

$ zenity --version

2.32.1

maybe the error is with the rest of your script, and not the zenity command itself?

Welcome to LinuxQuestions.

From the man pages.

--auto-close Close dialog when 100% has been reached

Since your starting at 100% zenity will instantly close. What you need to do is have your text count down and your bar count up. Here is a quick loop.

Code:

i=90

while sleep 1; do 

  y=$((100-$i))

  echo "# Shutdown? \nAutomatic shutdown in $y minutes"

  echo $((i++))

done | zenity --progress --title="autoshutdown" --auto-close

Wow. How could I have missed that... lol
Thanks!

For anyone interested, my perfectly working script now:

Code:

#!/bin/bash



CD=10  # number of minutes before shutdown



CDA=$CD

CDB=0

TOTAL=$(($CD * 60))  #minutes to secs

SEC=0

SCDN=1

(

while true

do

        echo "#Automatic shutdown in $CDA minutes, $SEC seconds.\nPress cancel to prevent automatic shutdown." 

        BAR=$(($CDB * 100 / $TOTAL))

        echo $BAR ; sleep 1

        if ! (( $CDB % 60 )) ; then

                (( CDA-- ))

                SCDN=1

        fi

        (( CDB++ ))

        SEC=$((60 - $SCDN))

        (( SCDN++ ))

done 

) | zenity --progress --title="autoshutdown" --auto-close



if [ "$?" = 1 ] ; then

        notify-send 'shutdown cancelled'

else

        notify-send 'shutdown initiated'

        sleep 3

        shutdown -p now
