Just interested in what other people have automated.

Here's what I have set up:
Code: 
#CRONTAB FILE 
# Classic crontab format:
# Minutes Hours Days Months WeekDays Command

#----AlarmClock----
30 4 * * * "C:\cron\Winamp\winamp.exe"

20 7 * * 1 C:\cron\WakeUp1.bat
45 7 * * 2 C:\cron\WakeUp2.bat
30 7 * * 3 C:\cron\WakeUp3.bat
45 7 * * 4 C:\cron\WakeUp4.bat
20 7 * * 5 C:\cron\WakeUp5.bat
#20 7 * * 6 C:\cron\WakeUp5.bat
#20 7 * * 7 C:\cron\WakeUp5.bat

#----Desktop Background----
01 7 * * 1 "C:\cron\Desktop (10).bat"
01 7 * * 2 "C:\cron\Desktop (9).bat"
01 7 * * 3 "C:\cron\Desktop (8).bat"
01 7 * * 4 "C:\cron\Desktop (3).bat"

I had it set up as an alarm but it didn't work so I turned it off.

..I use to have it setup to run a backup script I wrote when I was developing my own DE using fvwm.
 
Oh, I was just thinking about setting up some cron stuff last week. I want to write a script that sorts through some of my mail boxes and cleans out spam and such.

Any good cron tutorials out there?
 
I'm in a contentious situation with a supervisor at an employer. I have a script set up in cron to check an email account every set time interval. If I email a certain "kill switch" to an email account, it will render the server in to a non-functional state.
 
I cron everything and I'm working on cronning myself out of a job. Here's the latest.

Problem to solve: I love CBC's As It Happens, but I'm not always near the radio when it's on. The cron calls the script, and the script records the ogg stream to /htdocs and kills itself after 90 minutes when the show's over.

Code: 
# Record AIH daily
30 18 * * * /home/anthem/recordcbc.sh

Code: 
~# cat recordcbc.sh

#!/bin/bash
runtime=${1:-90m}
mypid=$$
# Run aih in background
/usr/bin/vlc --intf dummy --http-caching 5000 mms://a888.l961736887.c9617.g.lm.akamaistream.net/d/888/9617/v0001/reflector:36887 --sout '#transcode{acodec=vorb,ab=96,channels=2}:duplicate{dst=std{access=file,mux=ogg,dst=/var/www/htdocs/public/stream.ogg}}'&
aihpid=$!
#Sleep for the specified time.
sleep $runtime
kill -s SIGTERM $aihpid
mv /var/www/htdocs/public/stream.ogg /var/www/htdocs/public/`date '+%y%m%d'`.ogg

I don't TELL them I've cronned it all, they just think I'm really anal and mail out my network status reports at exactly 2:37 every morning (also showing that I'm working to all hours.)

First one does a daily nmap and compares it to the previous one to see if anybody attached any devices or opened new ports on the company network.

Second one does a weekly nessus scan and posts the results to a web page.

What I'm working on now is for the first to trigger the second, so any network change automatically get its ass nessussed.

Click to expand...

Any cron tutorial will just show you syntax for the timing of what you're running. What you need is scripts (or windows "batches"*) that do all the dirty work. cron just runs those on a schedule.

I had another one back in the TWS.net days to wget a daily map of TW's asskicking.

Hey where's you awesome sig? ...or was that Thanatos?

*Batches? We don' need no steenkin' batches!
