Note the first file in the archive should always be “mimetype”.

mysql databasename -u username -p -e “select * from Table” > ./file.txt

autocorrect=”off” autocapitalize=”off”

Note the use of the keyword “off”. It seems to ignore you if you try to use “false” instead.

1) Connect the new drive to your Mac using an external USB dock.

2) Insert your OS X DVD (Snow Leopard) and use “startup disk” to have your system reboot from the DVD. Or, you can just reboot and hold down the ‘C’ key on your keyboard to make it boot from the DVD.

3) From the installer program, go to utilities and launch disk utility.

4) Erase the new drive and create a partition (Mac OS Extended Journaled). I’ve had problems using the entire disk in the past. I recommend you size the partition to be slightly smaller than the entire disk. A few hundred MB is probably enough. You can drag-and-resize the partition right in disk utility.

5) Using the restore function, drag the original hard drive to the source box and drag your new disk partition to the destination box. I unchecked the option to erase the drive again and let it just copy over all the files from the original drive. Once you start, it will probably take a few hours.

6) Quit disk utility, shut down and physically swap out the hard drives and boot up from the new one.

Slight variations from this process in the past have resulted in problems such as startup disk not being able to bless the new disk and make it bootable which is very frustrating of course.

Here is a quick tip to get your installation ID if you can’t view it in the activation window. Run cmd.exe as administrator and type ‘slmgr -dti‘. This will display your entire installation ID in a popup window. When the system gives you numbers to type in to reactivate, the same problem may occur where the input boxes are cut off and out of view. Type the numbers even if you can’t see them and as long as you don’t make a typo, it will accept them and activate.

1) Telnet to port 25 of your mail server.
telnet your.mailserver.com 25

2) Issue some SMTP commands starting with this.
HELO random.victim.com
The server will respond with something like this:
250 your.mailserver.com Hello so.and.so [XX.XXX.XXX.XX], pleased to meet you

3) Now you type this.
MAIL FROM: yourself@random.victim.com
The server will respond with something like this:
250 2.1.0 you@random.victim.com… Sender ok

4) Now you type this.
RCPT TO: asdfasdf@your.mailserver.com
The server SHOULD respond with a 550 like this:
550 5.1.1 asdfasdf@your.mailserver.com… User unknown

If instead it responds with something like this, then your server configuration probably needs fixed to prevent backscatter:
250 2.1.5 asdfasdf@your.mailserver.com

While trying to install the latest update to Parallels Desktop 5, I ran into an installation road block because the installer claimed 10 different Parallels applications were running and needed to be closed. Clearly, this was not the case. My first thought was to blame Parallels, but then an Adobe Acrobat and Adobe Reader update failed for the same reason–the installer claimed certain applications were running when they were not. While using the OS X Terminal, I realized certain commands were not working. I could not “less” a file. “grep” returned nothing even when I searched for strings that were clearly there. It turns out my entire /usr/bin directory had multiple executable files showing 0 bytes! “less” showed 0 bytes and also showed thousands of links to it–the same was true for many standard command line utilities. Installers like Parallels and Adobe depend on command line utilities found in /usr/bin. For example, to determine if certain programs are running, the installer will run a shell script that uses the “ps” command. If you’re curious what that would look like, here is the exact script that Parallels Desktop 5 uses:

#!/bin/sh

if ps -w -w -A -ocommand | grep -nq ‘^/Library/Parallels/Parallels Server.app/Contents/MacOS/prl_vm_app’; then

exit 1

fi

if ps -w -w -A -ocommand | grep -nq ‘^/Library/Parallels/Parallels Service.app/Contents/MacOS/prl_vm_app’; then

exit 1

fi

exit 0
