Way, way too many times, I've seen some sort of process chewing up all my system processing cycles in Windows. Unfortunately, many times if I try to kill these processes, the system won't let me stating "access is denied". To work around this, use the following command to start up the task manager as "system".

at TIME /interactive taskmgr

where TIME is 1 minute from now.

Here's some examples of bash loops:

#!/bin/bash
for i in $( ls ); do
echo item: $i
done

#!/bin/bash
for i in `seq 1 10`;
do
echo $i
done

#!/bin/bash
COUNTER=0
while [ $COUNTER -lt 10 ]; do
echo The counter is $COUNTER
let COUNTER=COUNTER+1
done

#!/bin/bash
COUNTER=20
until [ $COUNTER -lt 10 ]; do
echo COUNTER $COUNTER
let COUNTER-=1
done

As I shift to UDEV, it is helpful to know how to get information about a particular device in order to set up a UDEV rule. Here's how to get that information:

udevinfo -a -p `udevinfo -q path -n /dev/sda1`

And here is the command to reload the rules:

udevcontrol reload_rules

Here's how to rebuild the indexes for Cyrus IMAP. It uses the program squatter for the indexing. This needs to be run as user 'cyrus'

for i in strav sportchk derv; do /usr/sbin/squatter -r -v user.$i; done

For some time now I've had issues with PowerDVD for playback. The screen would be black except for the borders where you coould actually see the movie playing. I've done search after search and never found a resolution until now. Apparently there is a conflict with ObjectDock. Simply unload ObjectDock and PowerDVD works like a champ.
