My growing list of Mac Terminal Commands -- BSD

ssh - username@server.name to connect


cut - This will cut off a line or lines from a given line number to another


grep - awesomely awesome searching tool within the shell


xaurgs - I'm not sure what this means or does but it has the effect of saying "I REALLY MEANT IT" when you execute a command


ps - this will list processes


pwd - this will tell you what your current directory is.


ls - this will list the contents of a directory


cd - this will change you from one directory to another


mkdir - this will make new directory


rmdir - this will remove a directory


man - typing this command with another will return the manual for the command that follows it ie man ssh will give me the manual for the ssh command.


vi - console text processor


> - placing this after a command will write the commands output to a file ps > ~/desktop/processes.txt  will create a text file on the desktop that shows the outout of the ps command. 


| -  this is called pipe and it will pass the output of a one command to another command for example ps | grep 1234 will send the out put of ps to grep and grep will then return instances of the string 1234


logout - ends a session


exit - ends a session


clear - clears the console screen.


say - will call the Mac text to speech app and then speak whatever text you put after the command you can also have it read a file alternately you can have it speak into a file to be played at a later time.


pcast - this will invoke the podcast application, it has about a million flags --server -- user -- pass --camera --start --listworkflows are some of the most important


nano - the Mac BSD super tiny text processor tool the replacement for pico, although pico is still available


host - this tool will return to you the dns lookup information for the host you define.  e.g.  host aces.uiuc.edu  will return aces.uiuc.edu has address 128.174.122.17 aces.uiuc.edu mail is handled by 5 incoming-relays.cites.uiuc.edu.  If you type host 128.174.122.17 the output is 17.122.174.128.in-addr.arpa domain name pointer rhl1.aces.uiuc.edu.


nslookup - another DNS reverse lookup tool that can be leveraged from the Mac PS terminal.

Amazing technology from Japan

 

 

 

 

Amazing technology from Japan . . .



Look closely and guess what they could be...



Are they pens with cameras?  
NO




Any wild guesses?
No clue yet?  NOT YET
 



Ladies and gentlemen... congratulations!
You've just looked into the future...
yep that's right!

You've just seen something that will replace your PC in the near future.

Here is how it works:



In the revolution of miniature computers, scientists have made great developments with bluetooth technology...



These are the forthcoming computers you can carry in your pockets .



This "pen type of instrument" produces both the monitor as well as the keyboard on any flat surface from where you can carry out functions you would normally do on your desktop computer.


 





Can anyone say,
"Good-bye laptops!"

Dear Dell: Thank You


Hello Client Name:

Please allow me to introduce myself. My name is Tech Name and I will be helping Unit Name with IT needs. Secretary Name forwarded me your questions about the differences between the Toshiba and Dell. I think you raise an excellent question that is definitely worth an answer.

There are several reasons that I recommend Dell’s exclusively for my support environment. One of the biggest factors is the Dell Next Business Day Gold Warranty with Complete Care Protection. Basically it provides three things that other computer manufacturers don’t provide:

1. A quick and easy channel for me to contact Dell, because of Gold Support I rarely if ever wait on hold for hardware technical support. In addition Gold Support allows me to do my own troubleshooting and then report that to Dell instead having to wait while I go through the same troubleshooting steps that I’ve already done while a Dell tech is on the phone with me.

2. Next Business Day on-site support. Very few companies offer true Next Business Day on-site support. Dell’s NBD support is quite good. Also, I have experience with nearly all of the Dell Techs in the area and have come to know many of them by name which means I have greater confidence in their repairs. Also since a technician is dispatched for any hardware related repair it allows me to manage my time effectively, letting the trained Dell technician use their expertise, allowing me to not have to learn how to repair every model that Dell sells. Laptop repair can be especially labor intensive and tedious if you don’t do it all the time. As a quick example, It once took me 90 min to get a single key replaced on a laptop keyboard. I watched a Dell technician do it in about 90 seconds.

3. Finally the best feature of the warranty that I specified is the Complete Care option. For the length of the warranty Dell will fix any damage to your laptop regardless of how it occurred. This means that even if you accidentally drop your laptop down the stairs they will make it right. It also means that if after 2 and half years when all of the letters are worn off your keyboard from lots of use, they will send out a technician with a new, no questions asked.

This warranty explicitly costs $218.00, however its value is quickly realized especially after the first year, after other model's warranties have expired. If for example your system board were to fail after a one year warranty were expired. It would cost about $500.00 dollars to buy just the part and then an hour to an hour and a half’s worth of labor $50-100/hour. The turn around time on repairs of this nature are often longer than one business day because the troubleshooting involved, if complicated could require the replacement and return of various parts in order to weed out the real issue. With the Dell solution, if they’re not sure they just replace all of them.

In addition to the warranty, since there are several units of this laptop series within the Insert Office Name and my support purview I can offer accessory loans. (if a power adapter is left at home for example) I can also setup units of like model much faster in the event of catastrophic data loss such as the failure of a hard drive.

I believe that all of these factors combined make spending the extra money on a Dell worth it.

Finally, a personal anecdote regarding the value of Dell’s warranty;

Recently my Dell Latitude D600 died. By “died” I mean that when I hit the power button there was absolutely no response of any kind. This was true when I tried powering it up with a fresh battery or a power supply. Knowing that I had at least a little warranty left, I called Dell’s Gold Support. My tech was Tony a friendly guy based out of Idaho. He had me try the one thing I had neglected, take out the battery and try to run it just on the power supply. So, I did, or at least I attempted to… I’m sure it sounded pretty funny from his end of the phone as I plugged the unit in.


Me: “Ahh Ohhh Jeeez…Whoa!!!”

Tony: “What’s wrong sir!”

Me: “Oh Man! I just went to plug the power supply in and sparks shot out the back.”

Tony: ..audible pause…ummmm…seemingly concerned silence..”How big were the sparks?”

Me: “Pretty big. I mean it wasn’t just static electricity, they shot out the back.”

Tony: “How far? An inch…more?”

Me: “Oh no probably six inches, it was kind of scary!”

After that exchange I was place on hold for a few minutes. Tony said something clever like, “I’d rather send you a new laptop than have you standing outside your house later this week watching it burn down.” I agreed.

Typically when Dell replaces a laptop like this they send a refurbished model. However it just so happens that they were fresh out. So… I got a brand new Dell Latitude D620. It arrived yesterday, and it is cool.

Dear Dell, Thank you.

Dear Dell, Please Update your Standard PC Image!

Today I got a peak at the all new Dell Optiplex 745.  For some reason they have dropped the GX distinction on this Optiplex model, not sure why, but I can go with change.  After cracking open the case to notice just how cramped it is in there I hooked it up to see how she performed and to create a new Standard image for my clients. 

The out of the box boot up time was lightning.  In fact I was through all of the standard next, next, next, reboot wizards in record time.  After grabbing the installers for all the stuff I wanted to install I took a peak at the All programs list, and very shortly after that the Add/Remove Programs control panel.  Goodbye to Google Desktop/ Google IE Search Bar.  Where is the Dell DVD codec?  Where is the Roxio RecordNow installation?  Hmm Maybe I forgot to order it, Nope don't think so.  One saving grace is that the Embasy Trust Suite was not installed, however there was a pesky icon on the All Programs listing to install it with a simple click.  Whew, delete that.  (The Embassy Trust Suite is Dell's attempt at securing the Windows XP file system.  I'm not saying that its a bad program, it just completely hoses the system if you install it with Network Associates McAfee Virus Scan Enterprise 8.0.i.,  I learned that one the hard way.)

So far so mediocre.  Now for the thing that makes my blood pressure rise a little.  I click to update the OS thinking that I may have a dozen or so updates since Dell was able to create the image for this new hot model. (It has an Intel CORE 2 Duo Processor, with something like a GHz FSB, and L2Cache). 

43 CRITICAL UPDATES NEEDED!!!

Dell What are you thinking, shipping a new Desktop PC that needs 43 Critical Updates to the OS!  It seems that the Google Software is plenty up to date.  I suppose that's because they paid a premium for their "partnership" in the new Optiplex Line.  I've always liked Google, but come on 43 CRITICAL updates.  Please update your image.

Experts Exchange Member

The office just picked up an Experts Exchange http://experts-exchange.com membership and I have to admit that it is a really great site.  I had noticed in the past that when I would google for a really esoteric and tricky problem I almost always got an EE article that I couldn't read all of becasue I wasn't a member.  Now that I can see the articles wow!That thing is choc' full O' techie goodness.  I think between reading that and the Outlook/Exchange google groups I might acutally learn enough to continue to be usefull.

BIOS & CMOS

So I'm picking back up on the A+ thing. Some notes about CMOS and BIOS.

BIOS = Basic Input Output System.
It is firmware that is stored on a ROM chip. This information is the basic information that the computer needs to start up. For example the first thing that runs in when the BIOS kicks off is the POST or Power On Self Test. This makes sure that important pieces of hardware are available for use, for example the keyboard. BIOS is automatic and when the CPU receives power the BIOS automatically loads and executes.

CMOS Memory = special memory chip powered by its own dedicated battery. Ususally a little 3 volt jobby. CMOS holds the settings that the BIOS uses. It has all of the basic configuration data that your computer needs to start up. Examples of data in CMOS are: Current Date and Time, Hard Drive Type, IDE Primary and Secondary Masters, Boot Order, Floppy Drive Type, Serial and Parallel ports, shadow BIOS (this means the BIOS can load itself into RAM where it can execute faster) finally, whether or not the OS is Plug-and-Play.

Getting into the CMOS editor is different for different Hardware Mfgrs. I often call this getting into the BIOS, actually what I'm doing is accessing the CMOS editor.
AMI BIOS = Delete Key
Award BIOS = Delete, Ctrl+Alt+Insert
Phoenix BIOS = F1, Ctrl+Alt+Escape, Ctrl+Alt+S
IBM = Ctrl+Alt+Insert
Dell = F2

Using Non-Western/Non-English character sets in Windows XP

Please see this tutorial for how to use Non-Western/Non-English character sets in Windows XP Professional. I think it is a really good document showing you how to set this up with pictures.

It was originally written for my missionary friends who left for Ukraine in June. However, I think others might benefit from it as well.
