Hi,

"countdown" to what ?

- shutdown ?
- PHP / javascript ?

what is the purpose of the countdown that you need.

You are asking a question not quite specific, like "my car is broken, what is wrong " type of question that nobody can help.

Please write what do you need to do and what have you done by now, so you can get appropriate answer.
Otherwise you will get
"Google didn't yeild any great results."

Just a simple countdown timer so I can time when I need to pull things out of the oven, know when the dryer is done, ect.

I use KAlarm (part of KDE).

I used to use kteatime when I ran KDE. Not sue what's available for other DEs though.

You could use sleep

Sleep 5 min and then play a sound.

Code:

sleep 300 && mplayer audiofile.mp3

Sleep 1 min and then have espeak say wake up.

Code:

sleep 60 && espeak "wake up" 2>/dev/null

Or something simple like

Code:

sleep 5 && xterm -fg yellow -T "Wake Up" -g 40x10

A nice tcl/tk timer. You will have to edit it to replace the alarm sound with one you like.

Code:

#!/usr/bin/wish -f
	set intime [lindex $argv 0]
	set intimeI [expr $intime * 60]	

      proc countdown {seconds} {
          init
          countdown_kernel $seconds
      }
      
      
      proc countdown_kernel seconds {
          hands $seconds
          if !$seconds return
          after 1000[list countdown_kernel [incr seconds -1]]
      }
      
      
      proc draw_hand {angle decorations} {
          eval .c create line $::size $::size [get_xy $angle] $decorations
      }
      
      
      proc end_coordinate difference {
          set hand_length [expr $::size * .9]
          return [expr $::size + $hand_length * $difference]
      }
      
      
      proc get_xy angle {
          return[list [end_coordinate [expr sin($angle)]] \
                       [end_coordinate [expr -cos($angle)]]]
      }
      
      
      proc hands seconds {
          catch {.c delete withtag hands}
      
          set twopi 6.283185
          set seconds_angle [expr $seconds * $twopi / 60.]
          draw_hand $seconds_angle "-width 1 -tags hands"
          set minutes_angle [expr $seconds_angle / 60.]
          draw_hand $minutes_angle \
                       "-width 3 -capstyle projecting -tags hands"
      }
      
      proc init {} {
          catch {destroy .c}
          set ::size 90
          set full_diameter [expr 2 * $::size]
          pack [canvas .c -width $full_diameter -height $full_diameter]
          set border 2
          set diameter [expr 2 * $::size - $border]
          .c create oval $border $border \
                         $diameter $diameter \
                         -fill darkred -outline gold  
      }

	  proc helw {} {
			  wm title . "TIME IS UP!"
			   button .bHello -text "                         Times Up!                        " -command exit
			   pack .bHello
			   exec play /usr/share/sounds/tinsha.wav &
	   }
      
      
      countdown $intimeI 
	after [expr $intimeI * 1000]  helw   

	

#	  puts stdout "Time is $intimeI"

It needs an arguement to start. So if you save it as "timer", make it executable and start it for example with "timer 10" if you want to time 10 minutes. I have it bound to keys in fluxbox to time different kinds of tea.

The one on this page looks interesting and fairly easy to customize:

Sorry, I don't know how to code in Linux. I was just looking for an program that would install easy on Fedora running the LXDE desktop.

i did a search using yum:

Well I'm not using GNOME or XFCE.

schneidz · 06-11-2012, 06:28 AM

i came up with this:

Code:

i=10; while [ $i -gt 0 ]; do echo $i seconds remaining; i=`expr $i - 1`; sleep 1;  done

if you need it to be gui, i'll see if i can wrap it around zenity.

Googling "stopwatch fedora" or "stopwatch linux" turned up not much of anything (I googled for stopwatch figuring I might have more luck by finding a stopwatch with a countdown function than I would googling for "counter").

I found this. It counts up, not down, but it might be worth a look.

What about Alarm-clock ?
By the way you describe what tasks you want I would use it.
