Fedora :: Crontab - Alarm Clock Functionality To Wake Up Computer
Jul 6, 2010
I have a feature that keeps me going back to Mac every night, and I was wondering if there was an equivalent. I have a nice app called alarm clock on Mac that plays music from my library on specified days of the week and times AND can wake the computer from sleep to do so. I was wondering if there was a Linux equivalent, such as crontab, that could do all those things. It's the last barrier to almost full time Linux use.

I am trying to set up an alarm via crontab. I can play music by "/usr/local/bin/mp3blaster /home/burak/Desktop/kemannnnn.mp3" command on terminal. However when I wrote this line in crontab it doesn't play:
04 19 * * * root /usr/local/bin/mp3blaster /home/burak/Desktop/kemannnnn.mp3

I'm running Ubuntu Hardy 8.04 and in the UK we changed from GMT to BST last Sunday (27th March)
On GMT I was waking on LAN at 23:30, all was working fine then we changed to BST. What I usually do is leave the BIOS clock on GMT and change the Wake on Alarm to 22:30. I did this, shut down Ubuntu fine, but its not waking up at all at 22:30, or any other time I set the WOA to. I had this problem a few years ago on an old ASrock mobo and cant remember how I sorted it - maybe by blanking the bios, cant remember.

I'm looking for an easy to use alarm clock program that I can suggest to new users. The two I have tried so far have fallen short of my expectations. "Alarm Clock" from the Ubuntu software repository starts out okay, but when the alarm actually goes off, getting it to stop seems pretty unintuitive. Click on the Alarm Clock icon, then click a Stop button in the new window that pops up. Sounds easy enough except that the icon used for "Stop" is just this grey square, so for users who are not familiar with linux or this program, it isn't even obvious that it is a button. I had one user actually uninstall the thing in order to get it to shut up. Preferably one should be able to silence the alarm by click on the alarm icon (or right clicking, if a 'doze' behavior is preferred) The other one I tried was alarm-clock-applet, which wants me to locate an alarm sound on my filesystem. Uh, no.
Does anyone know of a simple, basic alarm clock system that anyone can just sit down and immediately use without having to 'get in to the head' of the developer? Are the KDE alarms better? Am I missing something about either of these programs which would make them easier to use?

I installed 'Alarm Clock' from the Software Center and would like to have said app autostarts. There is an option in Alarm Clock to autostart with Gnome but that doesn't work so I assume the reason being I'm not root.
How to autostart Alarm Clock?
Also, in System > Preferences > Startup Applications, the 'Add' asks for a command. Is this like Windows whereas I simply point it to the app I want started? I don't even know where apps are installed. Who said ignorance is bliss?

So, I'm attempting to write an alarm clock from scratch without a GUI, doing this through a bash script. So far I wrote the file that actually initiates the song, and I was trying to set up a crontab so I could do it at a certain time, making it function like an alarm clock, but it isn't seeming to work, any input on why
Code:
SHELL=/bin/bash
12 5 * * * /home/angelo/music.sh
That is my crontab

I left the linux world for a few years and now i am trying to re-learn my shell scripting basics. I am writing a script for an alarm clock, but i seem to be running into a few issues.
declare -i H
declare -i M
declare -i currentH
declare -i currentM
declare -i minutesLeft
[code]....
My script, instead of doing what it should, produces the following errors:
./alarm: line 19: echo 11: No such file or directory
./alarm: line 26: 6: command not found
[code]....
and if i choose the time 11:06, files called 11 and 6 are creating in the working directory. I am sure it is something really simple, but i haven't used linux or scripting on my computers in around 6 years.

I'm trying to set up the Alarm Clock app to automatically launch Rhythm Box and begin playing a specific internet play lists I have there. I have one template set up to launch Pandora and I could probably get it to launch Rhythm Box but, how do I get it to launch Rhythm Box and begin playing a certain radio station playlist?

I must be overlooking something here, but I can't find out how to add "Alarm Clock Applet" to my panel. In Ubuntu Software Center, there's a picture of the program right in the panel and feature to add to panel, but there's no option for me to do this. "Add to Panel" doesn't have the application either.

My laptop's clock (Acer Extensa 5220) seems to be slow. I've corrected it 5 minutes forward last week and now have just corrected minute forward again. Is there a program [apart from time servers] to correct clock properly, for example, by shifting it a bit every hour? Is there already a program to put it to crontab or I should hack up a script? Or I should check more things?
I have found that HW clock is right, but system time is slow: about a second each 2.1 hours.
root@vi-notebook:~# dmesg | egrep 'clock|unstable'
[ 0.103785] Switching to clocksource tsc
[ 0.265274] Marking TSC unstable due to TSC halts in idle
[ 0.265514] Switching to clocksource acpi_pm
[ 1.321408] rtc_cmos 00:09: setting system clock to 2010-10-30 00:10:48 UTC (1288397448)
Is placing "hwlock --hctosys" to crontab a right thing?

I'm trying to make an "alarm clock" with mpd and gxmessage. Gxmessage allows you to assign unique exit codes for its buttons to use in your script. This is what I have so far:
Code:
#!/bin/bash
vol=$1
mpc clear
mpc load alarm
[Code].....
Now I know I'm way off with the case statement, because when the alarm_message function is called within the case, both of the exit codes I assigned to the buttons (-buttons "Stop":1,"Sleep":2 ) return to their default value.
What I would like is for every time the "Sleep" button is pressed, it would pause mpc, sleep for an amount of time, play, then open gxmessage again to restart the case statement (retaining the exit codes I assigned to the buttons). Am I on the right track?

This isn't stricly an Ubuntu question, but it is in the cause of an Ubuntu-powered home server Essentially: does wake-on-lan work if the computer is Shut Down (ie to all intents and purposes 'off' except for the hardware switch on the back), assuming that the motherboard and network interface (which in my case are one and the same) support wake-on-lan?
Also, if wake-on-lan is turned on, will this mean power going to anything other than the network interface (e.g. will PSU, CPU, case fans still be on?)Finally, will all of this work on Ubuntu 10.10 (assuming that the computer components are compatible)?
EDIT: Just to be clear, the Ubuntu system will be receiving the wake-on-lan 'call' (from a Squeezebox, though from my very limited knowledge of this stuff I don't think the source matters)

I have an interesting issue. I have a computer running Ubuntu 10.10. I have a wireless USB Microsoft keyboard attached to this, and I have a cheap USB infrared remote also attached to it.The wireless USB Microsoft keyboard can wake up the system from suspend. The USB infrared remote cannot.To start off, I made sure my /proc/acpi/wakeup had wakeup enabled for all usb devices.
Code:
xbmc:~$ cat /proc/acpi/wakeup
Device S-state Status Sysfs node

Is there any way to find out which device/event caused Ubuntu (10.10) to wake up from the most recent sleep/hibernation? I am trying to troubleshoot some sleep issues on a new box, and knowing what's causing it to wake up would help. I did check /var/log/pm-suspend.log but all it seems to say is Sat Dec 11 22:18:27 GMT 2010: Awake.

I have a dual core with an Intel integrated video HTPC (ubuntu 9.2). The suspend mode works for me and by pressing the power button, it wakes up the computer fine. How could I do the wake up from a keyboard, mouse or even a remote control,Does anyone know or has this issue?
When in sleep, keyboard and mouse seem to be dead, no response at all.

I just installed antix. It asked for time zones and I set all of that up but it is 3hrs off. My computer clock is correct, why can't I just set up antix to recognize my computer clock? Or why doesn't it just use that as a default?

Does anyone know or recommend some software or a script to remotely power on a PC from standby to on, or even better from completely off?
I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)

I added an ext4dev filesystem to my hard drive as /dev/sda3 and mounted at /share with the goal of putting all of my multimedia files on it and sharing it through NFS. I followed this guide: [url]
Of course, this was from lenny (hence the -dev). The partition was fine, and I mounted it numerous times. I also performed a dist-upgrade to squeeze. I shutdown that computer with the usual 'shutdown -h now' and disconnected the AC power cord from it, because I wasn't planning on using that machine for awhile. As far as I could determine, everything was fine before I unplugged it.
Every time that computer is powered off, the clock resets to 1999 because the battery is bad. So I am used to getting the "last mount time is in the future" error.
Three weeks after halting, I powered the computer back on. It was unplugged until this point. I got an error message when it attempted to mount /dev/sda3
I then removed its line from /etc/fstab, rebooted. and tried to check it, but I just keep getting the same error-- even with the '-b 8193' option.
The machine is still using the 2.6.26 kernel from lenny. I am building a new one right now (2.6.30), hoping that the problem is caused by the ext4dev/ext4 module. Otherwise I don't know what to do.

I have had some problems with Evolution. It sometimes freezes on start-up: I have to force it to quit. If I open "System Monitor", and end the evolution-alarm-notify task, then I can restart evolution successfully. I therefore suspect it is that which is causing trouble. What is it and how do I stop it?

I've been an ubuntu user for a while, and just started trying out fc15. In nautilus, there used to be an "emblems" side panel, as well as an emblems tab in the file properties window. (emblems being the little overlays you could assign to files or folders, like a tick or a cross or a smiley fdace or whatever). Is there some package I need to install to get this functionality back? Has it never been present in fedora, or is it a change in gnome3 / fc15?
