I tried alarm-clock-applet but i have to set up several countdown and i cannot launch them together, is however useful.

I would an app that let me use an only timer with multiple alarms. For example 30s+45s+60s+45s+120s (that aren' t countdowns) that i can launch wiht one click or even better set up to repeat X times.

Is possible maybe with some script? (An app would be better).

  • Could you clarify a bit? You'd call the script with parameters 30 45 60 45 120 cycle=5. Then an alarm sounds at 30 seconds, 75 seconds, 135 seconds, 180 seconds and 300 seconds? Then the cycle repeats 4 more times? Does a pop-up message appear simultaneously with the alarm? Do you already have an alarm file or will you be using system sound alert? Instead of parameters on command line do you envision a GUI panel with up to 10 timers + a cycle count? – WinEunuuchs2Unix May 23 '18 at 22:54
  • Yes an alarm sounds at 30 seconds, 75 seconds, 135 seconds, 180 seconds and 300 seconds, they are sequential. Then the cycle repeats x more times. A pop-up windows isn' t needed. I already have an alarm file. Yes a GUI would be better. – Scorpion Jun 5 '18 at 8:51

multi-timer bash script

The multi-timer bash script works in Ubuntu versions 14.04, 16.04 and 18.04. It also works in Windows 10 with Ubuntu 16.04 Desktop installed.

Features

  • Retains configuration between uses.
  • Up to 19 timers run sequentially in a set.
  • Progress bar for each timer.
  • Set of timers can be run multiple times.
  • Progress bar for set.
  • Progress bar for all sets.
  • Optional prompt to start each timer and/or set.
  • Optional pop-up message when each timer and/or set ends.
  • Optional alarm when each timer and/or set ends.
  • Optional lock screen when each timer OR set OR all sets end.
  • Optional interface to Sysmonitor Indicator so Systray shows countdowns.
  • Optional close progress bar display when all sets of timers end.

Requires yad package sudo apt install yad

Notebook Configuration Tab

yad (Yet Another Dialog) has a feature that allows multi-timer fields to be divided between two separate panels accessed within one window via notebook tabs.

The Configuration Tab lets you:

  • define time units in Seconds/Minutes
  • define how many times to run set of timers.
  • link to sound file used for timer alarms
  • option to lock screen at end of each timer, set, or all sets
  • additional options as illustrated below

Notebook Timers Tab

The Timers Tab allows you to:

  • Define alias for each timer rather than Timer 1, Timer 2, etc.
  • Set the number of seconds or minutes each timer runs.

Progress Bar Display

As multi-timer counts down progress bars are used for:

  • each active timer (zero duration timers are not shown)
  • each set (if two or more active timers in set)
  • all sets (if two or more sets run)

Bash Script

Copy and paste the bash script below to filename multi-timer. I suggest the directory /home/<your_user_name>/bin/. Afterwards mark the script as executable using:

chmod a+x /home/<your_user_name>/bin/multi-timer

Changing number of Timers

At line number 78, 79 and 80 you will see this:

# No. of timers default is 17 for 768 line screen and TMR_DURATION_NDX is 30
TMR_DURATION_NDX=30 # Set to 28 for 800x600 screen, 32 for 1920x1080 screen
MAX_TIMERS=17       # Set to 15 for 800x600 screen, 19 for 1920x1080 screen

Although 19 timers are supported, they might only fit on a 1920x1080 screen. About 17 (the default setting) will fit on the average 1024x768 screen. If you have Super VGA with 800x600 resolution you might only get 13 to 15 timers.

You must change the values on lines 85 & 86 at the same time:

Bash field name    ----------- Values to assign ---------
TMR_DURATION_NDX   23  24  25  26  27  28  29  30  31  32
MAX_TIMERS         10  11  12  13  14  15  16  17  18  19

eg If you want a maximum of 12 timers, set TMR_DURATION_NDX=25 and MAX_TIMERS=12.

After changing the Index and Maximum save the multi-timer file. If you have already run the program once a configuration file may have been created and it will have to be deleted. Use this command to remove the old configuration file:

`rm ~/.multi-timer`

Note that ~/ is a short cut to your home directory, ie /home/your_user_name/.

#           to delete configuration file before running update.

#       2018-06-19 Set fWindows flag to TRUE/FALSE instead of true/false.

#           Alarm only sounding for first timer but pop-up appears for all???
#           See changes to /etc/pulse/default.pa below:
#### Automatically suspend sinks/sources that become idle for too long
# Nov 4, 2018 - causes 3 to 5 second delay if last sound was 30 seconds ago.
# So you get sound delayed unpausing video or miss multi-timer alerts. Add #
# load-module module-suspend-on-idle
#           Although this fixes delay when switching between sound sources,
#           still change default alarm to sound file over 5 seconds long.

#       2018-12-05 HDD LED indicator flashing constantly while progress bars
#           are updated / program sleeps. Make LastWakeMicroSeconds dependant
#           on lost time log enabled only.

#       2019-03-23 Change default number of timers from 17 to 10 which suits
#           Windows 10 better and is more realistic number for most users.

Sysmonitor Indicator Interface

You can have the System Tray / Application Indicator Area update with the time remaining along with a "spinning text pizza" as illustrated in the GIF in above the bash listing.

To setup Sysmonitor Indicator see this Q&A: Can BASH display in systray as application indicator?

  • But i need to set seconds not minutes, is impossible with lock-screen-timer right? – Scorpion May 23 '18 at 11:44
  • Seconds can be changed to minutes with some minor changes. I'm off to work but I'll look at it tonight. – WinEunuuchs2Unix May 23 '18 at 11:46
  • Looks pretty good so far. Keep up the good work ! – Sergiy Kolodyazhnyy May 28 '18 at 20:54
  • Impressive work. +1ed – Sergiy Kolodyazhnyy Jun 1 '18 at 2:06

    It is not that i need a multitimer, i have enough with one in the morning and i would like to don't have to use it :D... But this deserves another +1 . And thank you for letting us know about yad. I knew zenity but it has an ugly warning message in the shell when you launch it. I will definitely try with yad the next time. – kcdtv Jun 1 '18 at 2:15
