So you’re using some old app, like FoxPro and it points to a drive letter. You only have one disk but need to spoof or mimic that drive letter. Well, subst to the rescue. Basically, pick a letter. Let’s say S: as it’s not currently in use. Then use the subst command followed by the letter followed by the path to map a drive letter to it. For example, if you want tot mount up c:/sales as S: then use this command: subst s: c:/sales Now, don’t misuse this command as a replacement for, let’s say net use. If it’s a network path still map it using the net use…

Regular Expressions
Basically, a regular expression is a pattern describing a certain amount of text. Their name comes from the mathematical theory on which they are based. But we will not dig into that. Since most people including myself are lazy to type, you will usually find the name abbreviated to regex or regexp. I prefer regex, because it is easy to pronounce the plural “regexes”.

Xsan: Metadata Network
Xsan needs an out-of-band metadata network. This network is used to transfer information, or metadata on files being written to the SAN. The metadata network on an Xsan should be low latency. Nothing should potentially interfere with the transfer of data. Therefore, make sure that you disable all the management features of your switch. But make sure it’s a good switch. I prefer to use a managed switch, disabling all the management features.

To start this off, I thought I’d cover a little of how I like to travel rather than little notes about where. So when I fly I like to be unencumbered with my bags. So I almost always check my bags. Then when I see people running up and down the isles trying to get their gargantuan bags crammed into little cubby holes I can laugh at them… Of course, this means I have to wait for my bag to come out on the carousel but that’s a small price to pay for…

The Basics of pico (or nano)
At your Unix shell prompt, type: pico filename Replace filename with the name of the file you want to create or edit. For example, to create a file and name it indiana.txt, type: pico charles.txt If the file already exits, Pico opens it for you to edit. If it doesn’t exist yet, Pico creates it and places you in an editing buffer. Pico displays a menu bar of commonly-used commands at the bottom of the screen. Pico accepts commands from your keyboard but not from your mouse. To insert text into your Pico editing screen at the cursor, just begin typing. Pico inserts the text to the left of the…
