this command will beep like an alarm for one minute from 18:57. you can change "1857" to your desired time.

you should have alsa-oss package installed, and you should also be root or part of "audio" group.

I'd prefer this one, you have to install espeak to get this running

Watch the temperatures of your CPU cores in real time at the command line. Press CONTROL+C to end.

GORY DETAILS: Your computer needs to support sensors (many laptops, for example, do not). You'll need to install the lm-sensors package if it isn't already installed. And it helps to run the `sensors-detect` command to set up your sensor kernel modules first. At the very end of the sensors-detect interactive shell prompt, answer YES to add the new lines to the list of kernel modules loaded at boot.

Just replace 15m with desired time. no suffix or 's' for seconds; 'h' for hours

You need to be root or in audio group to write to /dev/dsp.

You may use yes | head -n 2000 for about 1 second beep.

Wrote this as echo -e '\a' not always works as desired (ex. visual bell)

requires sp-auth installed

This command will auto kill sp-sc after vlc is closed, so u wont have to do it manually

A shorter version

Console screensaver.

Turn your terminal into digital clock.

Just a simple way without the need of additional tools. Of course, replace eth0 with your IF.

until (ssh [email protected] 2> /dev/null); do date; sleep 15; done

In this case will execute "date" then "sleep 15" until we are able to ssh into server, such as after a reboot

Could also be like:

until ( ping 10.1.1.39 1> /dev/null); do echo "server 10.1.1.39 is down"; sleep 15; done

Countdown clock - Counts down from $MIN minutes to zero.

I let the date command do the maths.

This version doesn't use seq.

A nice way to use the console in full screen without forget the current time.

you can too add other infos like cpu and mem use.

Does the same but without a pipe and a new shell.

sends notification msg within repeated intervals of time to notify-send ;)

Just for fun.

Mutes the speakers after an hour, in case you fall asleep watching a video...

I used curl instead of lynx.

No need for a colon, and one less semicolon too. Also untested.

There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.

Of course, a fifo is required for piloting the fade out of another song, but with a few bash function, we can mix music in bash like :

crossfadeIn > mplayerfifo1 & crossfadeOut > mplayerfifo2

loop 0 10 > mplayer fifo1

etc etc

can also be invoked as 'exipick -zi | exim -dM' if you do not need/want the delay between flushes.
