Commands using at

There are a lot of commands, which invokes your player at specified time. But I prefer not to jump from by bed, when alarm start to play. Instead, this script increases volume of mpd over time, which much more pleasant when you just woke up :)

Line can be modified as needed. This considers weekdays to be Mon-Fri. If run any working day it'll provide a parameters for the next working day for "at".

"beep" provided as a sample command.

This can be modified easily to include wait time. If you need something to run "D" days after today:

# D=4;if [ $(date +%u --date="${D} days") -lt 5 ];then AT="+${D} days";else AT="next monday";fi; echo "beep" | at noon ${AT}

Benefit is that it doesn't make you keep the terminal open.

Yep, now you can finally google from the command line!

Here's a readable version "for your pleasure"(c):

Kills all windows in a gnu screen session and terminates it , on pressing Control-f , useful in closing screen session with large number of windows . Add it to your screenrc .

The command when added in screenrc enables logging all open windows by using the C-l (control-l key combination) and disable by C-o . The lines need to be added in separate lines .

The simplest way to do it.

Works for me, at least. (Why are the variables being set?)

You can write a script that does this :

You think Expansys in all these countries will sell the HTC Desire for the same price? Well, you'll be surprised. Most of them will be sold at 499.99 EUR but the cheapest can be found in Germany and the most expensive, in Belgium.

setup for reminder in 5 days, added the date in the future. To run a job at 4pm three days from now, you would do at 4pm + 3 days, to run a job at 10:00am on July 31, you would do at 10am Jul 31 and to run a job at 1am tomorrow, you would do at 1am tomorrow.

you can also run "xmms2 pause & at now +5min

I like the order of the arguments better this way.

Nice little alarm clock to wake you up on time (hopefully).

You can also do 'echo "vlc path/to/song" | at 6:00

This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow.

Does require at, which some environments without crontab still do have.

You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped)

atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null

If you frequently need to connect to your ubersecure mainframe from various uberunsafe machines, you have to face difficult decision: (a) type the password everytime during the session (lame), (b) add local public key to mainframes authorized_keys file (unsafe), (c) as above, but remove this key at the end of the session (pain in the a55). So let's say you save The Command to tempauth file in bin directory of your mainframe's account and make it executable. Then, while you're on one of these unsafe ones, do:

and password prompts stop the harassment for 30 minutes and you don't have to care to remove the unsafe key after that.

Set an alarm to starts in specific time.

Downloads at 12:00

Replace "url" with the correct address of what your're downloading. Replace 01:00 with what time you want. (24-hour clock).

This is an alternative to cron which allows a one-off task to be scheduled for a certain time.
