Commands using write

In Mac OS X, by default, you have to click the mouse on a Terminal window before you can type in it. You can change this behavior to mimic the X11 behavior of focusing on the window on mouseover.

Insert an additional (moveable) spacer on the right side of the Dock in Mac OS X

Insert an additional (moveable) spacer on the left side of the Dock in Mac OS X

Change the file location in the second half of the string to the exact file location of your chosen picture.

Enables widgets to be placed onto the desktop. Click and hold the widget and press F12 to drag it onto the desktop. Repeat the process again to drag a widget back onto the dashboard. You may need to log off or restart for it to take effect.

Depending on the TERM, the terminfo version, ncurses version, etc.. you may be using a varied assortment of terminal escape codes. With this command you can easily find out exactly what is going on.. This is terminal escape zen!

"\33]4;%p1%d;rgb:%p2%{255}%*%{1000}%/%2.2X/%p3%{255}%*%{1000}%/%2.2X/%p4%{255}%*%{1000}%/%2.2X\33\\\33[!p\33[?3;4l\33[4l\33>\33[?12l\33[?25h\33[27m\33(B\33[m"

Lets say you want to find out what you need to echo in order to get the text to blink..

Now you can use this function instead of calling tput (tput is much smarter for portable code because it works differently depending on the current TERM, and tput -T anyterm works too.) to turn that echo into a much faster executing code. tput queries files, opens files, etc.. but echo is very strait and narrow.

So now you can do this:

This command will use the short username (ie: bsmith) instead of the full (or long) name (ie: Bob Smith), by default in the network authentication dialog, ie: when connecting to servers. Resulting in one less step/time saved.

Simply change the boolean value to "NO" (ie: "... -bool NO") to revert to the system's default behavior.

This command creates and burns a gapless audio CD with 99 tracks. Each track is a 30 second sine wave, the first is 1 Hz, the second 2 Hz, and so on, up to 99 Hz. This is useful for testing audio systems (how low can your bass go?) and for creating the constant vibrations needed to make non-Newtonian fluids (like cornstarch and water) crawl around.

Note, this temporarily creates 500MB of .cdda files in the current directory. If you don't use the "rm" at the end of the command, you can burn more disks using

Prerequisites: a blank CD-R in /dev/cdrw, sox (http://sox.sourceforge.net/), and cdrdao (http://cdrdao.sourceforge.net/). I'm also assuming a recent version of bash for the brace expansion (which just looks nicer than using seq(1), but isn't necessary).

When you press "cmd+n" in TextMate, you can have "HTML" language as default document format... You can also define other languages too. You need to know the UUID of your language bundle.

Swap TRUE with FALSE to turn it off again. Note: Finder must be relaunched afterwards to see the effect. For example like this:

Dashboard is OS X utility application. When you hit F12, Dashboard springs forward, dimming the background, some people have claimed memory or performance problems. In my case, I just don't use it, there may be other reasons you?d rather not have Dashboard available.

Change YES to NO to restore the previous functionality.

In Mac OS 9, the "New Folder" keyboard shortcut was Command+N, but in Mac OS X this was changed to "New Finder Window" instead, with "New Folder" taking the more awkward shortcut of Command+Shift+N. This command reverses their mappings.

Mac OS X 10.5 (Leopard) introduced a new, 3D, reflective Dock. For those of us who prefer the Dock to be a little less distracting, this command is the answer. The Dock will be rendered in the same style as when pinned to the left- or right-hand side of the screen. Replace YES with NO to restore the 3D Dock.

In Mac OS X, pressing Command+H will hide an application. While that application's windows vanish, there is no other visual feedback, meaning there is no immediate distinction between an application running with no windows open and a hidden application. This command turns hidden applications' icons transparent, providing a clear and obvious distinction.

Change YES to NO to restore the previous functionality.
