Posted by: Jennifer Zelazny | 0 Comments

Everyone needs a good UNIX quick reference for the times you cannot remeber the command you need, but you know exists, and I recently found a good one, good enough to bookmark until I compile my own. The Univeristy of Washington’s Quick Reference: Unix Commands

cheers! windows applications without windows.

Posted by: Jennifer Zelazny | 0 Comments

This weekend, in between validatint my code, football, and SoCom II, I ran into a cool project that I think is worth mentioning: Darwine. For people like me that do not always have access to a PC but believes in QA for multiple browsers/platforms, there are times when all I need is IE for Windows. I do not want to buy a PC or super slow Virtual PC…I just need to open a window or two in IE, look at it, make adjustments to my code and get on with my day. Enter: Darwine. Darwine is an open source project/port… Read More »

sed and awk.

Posted by: Jennifer Zelazny | 0 Comments

In my latest bit of training, I learned about sed and awk. sed is a line editor (stream editor) (scripting with ed). awk is a pattern-directed scanning and processing language and divides each line to fields by separating words by spaces or other specified field separators. Some tidbits about using sed to quickly edit files: To use multiple commands in one line, separate the commands by semi-colons ( ex. sed -n ‘/jappler/s/=/!/g ; /jappler/p’ jappler.txt) the example command will look for all lines with jappler and on those lines, it will replace all equal signs with exclamation points in the… Read More »

regular expressions help.

Posted by: Jennifer Zelazny | 0 Comments

No, the site was not hacked, I chose to write about regular expressions. I am in my last section of my UNIX/Linux Systems Administrator training and I am equally excited about regular expressions as I was about learning subnets. I know regular expressions are very powerful, and I remember enjoying subnets after I finally figured them out, so I will give it a shot. I just feel like I did when I was forced to take world history. Anyway, I already found a useful web site that covers the basics of regular expressions that I wanted to share.

growl.

Posted by: Jennifer Zelazny | 1 Comment

I am always looking for cool stuff for Mac OS X…and I have been carrying around a bookmark for growl for the last few months, and today I finally installed it. Growl is “a global notification system for Mac OS X .” Translation: something really cool that works with multiple apps. So you have mail checking mail all day and you would like to be notified of new mail, or perhaps you are listening to iTunes, and the song changes and you would like to know what you are listening to, growl will notify you with a cool little window….

more helpful UNIX stuff.

Posted by: Jennifer Zelazny | 0 Comments

While I am taking my UNIX/LINUX Systems Administration training, I pick up cool UNIX tidbits and it is time to share some more of my latest tidbits. (First installment) Random commands and information I have jotted down: When compiling something from source code, I used to always use: ./configure then make then make install, but I learned you can combine commands so you can use: ./configure; make together in one statement while compiling source code. Daemon stands for Disk And Execution MONitor Sometimes we don’t want to remove an account, but we need to disable it temporarily. A common way… Read More »

UNIX/LINUX training update.

Posted by: Jennifer Zelazny | 0 Comments

Well, two parts of my training done, and two more to go. I have to say, when I saw that I would have to spend 40 hours learning about networking and dns, I was a little worried, but now looking back at it, I really learned a lot and enjoyed what I learned. Who knew?

network help.

Well. Today I relived my college days as a student taking Math 110 (Business Calculus). I felt like I understood…so much that I thought I got a 90% or above on the exam…then reality would set in and I would get a 47%. Welcome to 2004, Networking/DNS now replaces Math 110…and I am stuck on trying to understand subnets. All day long tryng to figure all this out…but I have to say, I stumbled upon a great resource, and the reason for my posting: Learntosubnet.com. I hope others can benefit from this great resource like I did. I look forward… Read More »

configuring ipfw on mac os x 10.3.

Posted by: Jennifer Zelazny | 0 Comments

Sometimes the GUI is awesome. Sometimes you just need more control over your conf files that the GUI offers. I wanted to have more specific firewall rules for my computers and servers running Mac OS X Client, more than the default OS X 10.3 built-in firewall configuration that is provided. First, let’s look at all the files involved with Apple’s default firewall. System Preferences: Sharing: Firewall tab.If you want the security of a basic firewall, you can simply “start” the firewall. Using this option, Mac OS X will look at what services you have enabled (ex. Personal File Sharing, FTP,… Read More »

helpful UNIX commands.

Well, I am halfway through my UNIX filesystem training and I wanted to share some useful commands I have learned along the way: grep -i = grep ignoring cases grep -v name = grep ignoring all lines with “name” in it grep word * = grep in the current directory for all lines with “word” in it pwd = command to tell you waht directory you are in cat = will display files quickly (like pico but read only) hitting “q ” in while viewing a man page or other text will take you to a prompt less = reads… Read More »
