user@host ~ % sleep 60 ; echo "\a"  & 

should do, whatever you need
60 is time in seconds so put 3600 for an hour

with the & you can close the terminal

I learned a new bash command today - 'trap' . And to make the sound stop playing when you close the timer window you can add:

trap 'killall aplay' EXIT

at the beginning of the original script.

#!/usr/bin/bash
xterm -e "bash -c \"echo $TIME; read\""

Then I ran it like this:

$ TIME=3 countdown.sh

and it opened an xterm window and printed the number '3'.
Then I ran it your way, like this:

$ TIME=3 & countdown.sh

And it opened an empty window. I think when you insert a '&' it breaks up the simple command and makes it into two commands, so the variable is no longer set in the environment for the second command. It shouldn't be a problem to take out the '&' because setting a variable is non-blocking.

My altered code:
snip...

--field="   3 Minutes!/home/USER/alarm_96_icon.png":fbtn "bash -c '/home/USER/bin/newtimerwindow3 &  sleep 3m ; aplay /home/USER/alarm-1000.wav'" \

...end snip.

I would like to pass the variable TIME to this script:

#!/bin/bash
##script to open new countdown from newtimer script (yad)

xterm -fa 'Monospace' -fs 48 -geometry 20x4 -e 'bash -c "/home/USER/bin/countdowntimer 3"

Instead of "..countdowntimer 3", I've tested "..countdowntimer $TIME" - no luck.

As you see, it's all very crude, but fun and maybe even a bit functional.

Crude example:

--field="   3 Minutes!/home/USER/alarm_96_icon.png":fbtn "bash -c 'TIME=3 & /home/USER/bin/newtimerwindow &  sleep 3m ; aplay /home/USER/alarm-1000.wav'" \

In the receiving script I use $TIME , but it throws everything off, and nothing opens or happens. Like this:

cat bin/countdowntimer
#!/bin/bash

hour=0
## min="$1"
min="$TIME" 
sec=0
        while [ $hour -ge 0 ]; do
                 while [ $min -ge 0 ]; do
                         while [ $sec -ge 0 ]; do
                                 echo -ne "$hour:$min:$sec\033[0K\r"
                                 let "sec=sec-1"
                                 sleep 1
                         done
                         sec=59
                         let "min=min-1"
                 done
                 min=59
                 let "hour=hour-1"
         done

If you want a different theme/look you can add this at the top of the script:

export GTK_THEME="Clearlooks-Phenix-Sapphire"

Of course, chosen theme is up to taste. Or no taste.

Memory is just detritus that clogs the mind

detritus

If I were to use that word, I'd pillage and plunder it and make it detritusimus   

...as the title says, it's a simple countdown timer that I made for myself and my work. You can adjust the times in the code for your own needs. They're pretty self-explanatory.

After choosing a timer, you can close the window.

Dependencies: bash yad papirus-icon-theme

If you don't have papirus-icons, the icons may not show up on the GUI due to how they are named. You can change it in the code if needed. Just replace clock-applet-symbolic with your chosen icon's name in the code.

This is what the GUI looks like (on my systems). Click on a timer and close the window. The timer will still count down and sound off when it's finished despite closing the window.

If using alsa-only (aplay...as shown in the code below), you must use a .wav sound file. If using pulseaudio, you can use just about any type of sound file.

If you're using pulseaudio, replace aplay with paplay (adjust the code to your needs). I know nothing about pipewire, so I'm not sure what would be needed for that.

I didn't make a desktop.file for it; I just have the script in my file manager and execute it when needed. Sorry.

In the code below, you will also need to replace the path to the sound file that you want to use for the alarm.

Warning!!! Whatever sound file you choose, it will play the entire sound file. So, you might want to choose a file that's only a few seconds long.

The code...

#!/usr/bin/env bash

yad --form --columns=1 --width=260 --borders=5 --title="Timer" --no-buttons --height=250 --width=270 --window-icon="/usr/share/icons/Papirus-Light/24x24/panel/alarm-clock-panel.svg" --center --text-align=center --text="
