BLT is a perl application that integrates Twitter into the command-line, and to install BLT, perform the following option:

After you have BLT installed, run blt at the command line and it will ask you for your Twitter username and password. You may also want to run a blt --check to grab the latest tweets from your account after you have set up the user interface.

To stay up-to-date with your tweets, you will want to run the following option at the command line from your home directory:

Please feel free to leave any feedback that you have on this handy little Twitter application.

With this in mind, there is an application that you can install on your Linux box that acts a dock for you. This application is called KDocker.

This application is available for the following Linux distributions:

• Suse
• Slackware
• Red Hat
• Debian
• Kubuntu

For easy install in Ubuntu/Gnome, you can perform the following syntax in at the command line:

sudo apt-get install kdocker

This application is great for making your Linux GUI’s appearance like Apple OS X!

If you are familiar with vi, the find and replace string will be very familiar. The format of the find and replace is:

sed 's/oldstring/newstring/g' file.txt

However, if you are wanting these changes to be reflected in a file, you will need to perform an output at the end of your sed string, like so:

sed 's/oldstring/newstring/g' file.txt
> changedfile.txt

I have provided an example of how to use the principles below:

/System/Library/CoreServices/DefaultDesktop
.jpg (Leopard users)

/Library/Preferences/com.apple.loginwindow (Tiger users: modify this file)

Once this has been done, open a Terminal window and execute this line at the command prompt:

sudo defaults write
/Library/Preferences/com.apple.loginwindow
DesktopPicture '/Path/To/Picture.jpg' (all on one line)

Once this has been done, log out of your account. When you log out, you should instantly see the changes that you have made.

This app can be downloaded by doing: sudo apt-get install vim

VIM can also be an alternative to using vi, which only displays code in monochrome. Here is a comparison of between the physical appearances of vi and vim:

Terminal without vim – Just using vi


Terminal with vim

This also helps troubleshooting easier if you have an error somewhere in your HTML code. This color coding works for: HTML, XML, CSS, PHP, Perl, HtAccess, and many other languages.

Enjoy!

1. In Terminal, type emacs at the comment. Emacs will then appear for you.
2. In the Emacs window, press <ESC>. This will bring you to the note buffer section (shown below).
   
3. Once you are in the buffer section, press x, type in tetris, and then hit Enter.
4. Tetris will then appear for you (shown below).
   

To move your pieces around in Tetris, use your right/left arrow keys in the direction you want the piece to move. Your up/down arrow keys will change the position of the piece, and your space bar will shoot the piece down the bottom.

This is a fun and interesting Easter Egg included in this classic editor!

Thankfully, TheAppleBlog’s Andrew Bednarz has assembled a compendium of Mac OS X terminal tips, tweaks, and tricks. He shows how to use Visor, a cool program that provides an always-accessible pulldown terminal prompt just like the console in the video game Quake. He also shares some insider UNIX knowledge on tweaking Terminal.app to display color-coded directory listings and more informative command prompts.

Go check out his list of tips. Your command line will thank you.

grep --color "text" filename

Example:

If you want to get more specific in your lspci output (e.g. wanting just to display a certain brand), you can always do lspci | grep -i "Productname" which will only return results that includes the string from your grep command. For example, if I wanted to find all of the hardware made by Broadcom, I would do lspci | grep -i "broadcom" and the results would return only hardware that mentions Broadcom.

Although, this will only display hardware that is inside your computer, it will not display any hardware that is attached by USB. This is where the command lsusb comes in. Lsusb will list all of the USB ports you have in your computer and display any hardware specifications that are plugged-in to them as shown in the example below:

If so, there is a simple way around this. Just use this: find . | xargs grep "yahoo" * | more. I will break down these processes for you:

• find . – Find is a command that outputs the location of a file. In this case by specifying a ., the search will only be done in the present directory.
• xargs – This allows a command to be executed from standard input. This also helps force the grep command (coming next) to return output, even when the directory is too large.
• grep – The way we will be using this command is to search through a file for a specific string. If you are looking for straight text, it is best to use quotes (e.g. “text”) to help the command line decipher exactly what you are looking for. More info on grep can be found on this earlier post.
• more – This command is optional for this process. More would be best used if you were expecting a full page of output returned from your search, and want to be prompted for the next page. This option would be very beneficial if the string you are searching for would be common in your results.
