Variabel di Shell Script

In the previous issue we’ve become acquainted with a shell script and managed to create a very simple shell script. If we look, we did not perform any processing on the shell script. We only show a message on the screen and execute commands on the shell through shell script. What if we want to make the program more interactive shell script?

As with any programming language, shell script also serves to recognize the variables that can hold information temporarily for a variety of purposes, for example to compute or determine the output results. You may make as much as possible or use a variable in your shell script. Name the variables are independent, large and small letters should, but make it easier to remember, make it a habit to create standard rules in the manufacture of the variable name. At this writing, all variables will be written in lowercase.

Variables can be divided into two types, namely environment variables and user variables. Environment variables are variables that have been previously determined as a part of the shell used (bash). By default, the name of this variable using all capital letters. Example of this is the $ USER variable that will contain the user name you are currently using, $ HOME home directory which contains the address of the user that is used, and so forth. To display the entire value of an existing environment variable, you can use the set command in the terminal (Figure 1). User variable is the variable name specified by the user themselves and not by the shell used.

Variables can be accessed by using the dollar sign ($) before the variable name, for example, we have a variable named “my name”, to access the value stored in the variable, we use the $ my name. To give value to a variable, we use the sign “=” is immediately followed by the value we give without any spaces, for example my name = Willy. What if the value that we want to give is a sentence? Use double quotes as the opening and closing value of a variable, such as my name = “Willy Sudiarto Raharjo”. For example, see listing 1 and try running on your computer. Seen that the value of the variable Sudiarto be regarded as a command and not part of the variable because it is not enclosed in double quotation marks. Please be careful

Pre-Order Asus 31.5″ 4K IGZO Monitor for $3500

Asus is reportedly now taking pre-orders for its 31.5 inch monitor (PQ321Q) featuring Sharp’s anti-glare LED-backlit IGZO technology. It sports a screen resolution of 3840 x 2160, 140 pixels per inch, and not only cuts down on energy consumption but features an extremely long durability given that Sharp’s tech doesn’t constantly refresh the images. It’s all static until something moves on-screen.

The company introduced the new monitor last month, reporting that Sharp’s IGZO tech supports smaller transistors than amorphous silicon thanks to significantly higher electron mobility. It also not only reduces energy consumption, but reduces the monitor’s overall bulk as well: at 35 mm at its thickest point, the PQ321 is the thinnest 4K UHD monitor available today, the company said.

A Sharp rep said during CES 2013 in January that the 31.5 inch panel will be marketed to professionals first given the end-price. The prototype also had ten-point touch input which apparently didn’t make it into the company’s own PN-K321 31.5 inch IGZO monitor selling for $5,000 USD. The Asus model also doesn’t support touch.

The upcoming PQ321Q supports wide 176° horizontal and vertical viewing angles, 10 bit RGB “deep” color, and an 8 millisecond gray-to-gray response time. Other features include a 0.182 mm pixel pitch, a max brightness of 350 cd/m2, a max contrast ratio of 800:1, picture-by-picture support and HDCP support. The monitor’s typical power consumption is 93 watts.

On the connectivity front, the I/O panel has two HDMI ports, a DisplayPort, and an RS-232C port for old-school VGA connections. There’s also a 3.5 mm mini-jack for PC audio input, a 3.5 mm mini-jack for AV audio input, and a 3.5 mm mini-jack for earphones (for HDMI and DisplayPort).

Last month the company said that the new display is the “equivalent to four Full HD displays stacked side-by-side.” It can now be pre-ordered on Amazon here, and on Newegg here, both requesting $3,499.99 USD. The monitor is slated to arrive on July 16, 2013.
