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 in giving a value to a variable.

You can combine environment variables and user variables in a shell script is the same, as in listing 2. What if want to write a message using the $ character, such as “It cost me $ 15”? If we are not careful, it could be a shell script would be wrong to interpret the information that we provide and try to take the value of variable 1 (which will not contain any) and display it as a “price 5”. To fix this, use the escape character to indicate that the next character will be recognized as a regular character and not as a substitute for a variable, which marks the backslash “\” as in listing 3.

One character that needs more attention is the backtick character “` “(position number 1 on the left side your keyboard) because this character has a special function in shell programming, which is able to accommodate the output of a shell command in a variable. As an example, we will hold the result of the date command into a variable date and display its contents using the echo command as in listing 4.

To be able to receive input from the user and store it into a variable, we can use the read function is followed by the name of the variable that we want to use to store the values ​​as in Example 5 listings.

Cool, Indonesian People Make “Printer” 3D

Starting from his love for the graphic design world, John Djauhari now assembling machines printer (printer) 3D. By leveraging open source technology, 3D printers that can print documents assembled Johanes digital into three-dimensional objects.

John worked as a product designer. Some clients who want to make a product sometimes is not satisfied if only to see the design in the form of digital documents. They want physical shape despite the small size.

“Well, from there, why do not I make a 3D printer itself,” he said when met at the show Popcon KompasTekno Asia 2013 in Jakarta Convention Center, beginning last July.

John also likes the toys (toys). Many colleagues who designed character toys and wanted to realize his ideas into tangible form. Some of them use the services of John for 3D printing.

John also likes the toys (toys). Many colleagues who designed character toys and wanted to realize his ideas into tangible form. Some of them use the services of John for 3D printing.

Keseriusan Johanes merakit printer 3D dimulai pada 2011. Ia mendirikan Bikin Bikin 3D Print dan aktif ikut pameran untuk memperkenalkan teknologi ini. Kala itu, desain luar printer buatannya masih berupa kerangka. Setelah melewati beberapa kali pengembangan, kini printer 3D-nya semakin akurat dan didesain menggunakan casing. “Akurasinya sampai 0,2 mm,” tutur Johanes.

Akurasi itu dibuktikan dengan mencetak replika arca yang penuh detail dan lekukan. Johanes terlebih dahulu memindai seluruh bagian arca asli yang tersimpan di Museum Nasional. Setelah mendapat filepindainya, mulailah Johanes mendesain 3D lalu mencetak dengan printer buatannya sendiri.

Memanfaatkan “open source

Dalam mengembangkan printer 3D, Johanes memanfaatkan teknologi open source untuk driver dansoftware. Ia ikut dalam forum internet yang khusus membahas teknologi printer 3D.

“Di forum ini, kita bisa tahu kalau ada algoritma yang lebih baik dan memberi struktur lebih mudah. Bukan cuma soal teknis, dari sana juga kita tahu soal materi yang mudah dicari dan lebih terjangkau,” jelasnya.

Untuk mendesain bentuk 3D, Johanes menggunakan software Pronter Face dan Repetier. Komputer yang dipakainya terhubung ke motherboard printer melalui kabel USB. Motherboard inilah yang memerintahkan gerakan koordinat X, Y, dan Z, menerjemahkan dokumen digital menjadi obyek nyata 3D.

Printer 3D yang dibuat Johanes masuk dalam tahap pengembangan akhir. Ia membuka pre-orderdengan harga Rp 10 juta. Setelah masa pre-order berakhir pada September 2013, printer 3D bakal dibanderol Rp 12 juta.

Getting to know Jack Dorsey, the Twitter Author

Is one of the requirements to be successful is a must have dropped out of college? For those who do not agree with that statement, Bill Gates, Steve Jobs, Mark Zuckerberg has proved the above statement is true.

Now, a New York University student born 19 November 1976, Jack Dorsey, co-joined to the above statement agrees with being one of the success with the brilliant work; Twitter.

Perhaps the name of the new Jack Dorsey first heard in your ears, or just this once you read it. In fact he was the one creating ‘toy’ in today’s internet era that could be very, very you gandrungi.

He is the creator of a social network with the concept of micro-blogging, Twitter. That the college years never removed from the campus where he learned about the computer.

Dorsey was born in St. Louis, Missouri, 37 years ago. And there precisely he grew up with curiosity about computers and communications were also great. Dorsey teen has started his desire to dive into programming since he was 15 years old.

And continued when he was in high school, Bishop DuBourg High School name. Where he pursue any science, and especially, computers and programming.

Dorsey teens start to find out and follow your passion when he was struck with a computer program that manages and coordinates a taxi passing by the system very well organized and quick.

How cars taxi, or car delivery can regularly meet and work quickly calls. Of interest arises where a similar program to create a more sophisticated, when he was only 15 years old.

Dorsey adults continue his studies at the Missouri University of Science and Technology. The study period was completed and continued to move to New York University who also never finish it. Or in another sense, Dorsey dropped out of university.

Because it takes time and concentration to build his company. Dorsey moved to Oakland, California, in 2000 and built a company engaged in the field of programming.

He sold the software on line pengkoordinir taxi he had ever made as a teenager in the web that he made himself. And the company continues to grow by selling software creation via the Internet.

Through his company is the way Dorsey met with people like Biz Stone and Evan Williams who later would become his partner in founding Twitter.

What’s in your mind when you want to create a Twitter Dorsey? Narrated by Biz Stone, Dorsey has wild ideas in his head. “Just imagine if we could share with our friends about what we are doing and what we feel now, imagine. Is not it great? “Said Dorsey.

Biz Stone, a former CEO of Odeo, and Evan Williams-one of the founders blogger, agrees that desire and build company called Obvious, who would soon be renamed Twitter.

Social networking on the initial launch is not so attractive to everyone, but it has now become one of the most social media enjoyed by most citizens of the world. Which may also be one of the ‘toy’ bored repellent for you.
