It is undeniable that over time, the popularity of Linux is increasing every day. Linux Kernel project which was originally just a fun project by Linux apparently transformed into a project that became the basis for the evolution of the digital world today.
We can see that more and more digital devices are therein using Linux in it. Changes were made in all areas so that Linux can be used by all users, both from the ground level up to the experts though.
One thing that remains a hallmark of Linux is the existence of a shell that is never lost on any Linux distro. Shell is a command-line interpreter on duty to translate the commands entered by the user directly to the system through the help of a terminal or console as a zoom interface (such as Command Prompt on the Windows platform). Although today most of the Linux distributions already to offering graphical display, the shell is still regarded as one of the strengths of Linux shell bridge where users can interact with the system in order to be more flexible. Many things can be done on a shell because we are dealing directly with the system, coupled with the many variants of the shell that offers a variety of features in it, such as csh, sh, bash, ksh, tcsh, ash, zsh, etc.
One of the most common type of shell used is BASH (Bourne-Again Shell) which was created by Bryan Fox in 1988. Shell is a replacement of the Bourne Shell (sh) existing first and is still used in some Linux distributions. Currently BASH shell has become a de facto standard for almost all Linux distributions because it is considered the most feature-rich and has a fairly high degree of portability. For comparison between variants shell can be seen on the Wikipedia website
To be able to understand the Linux system with better and also improve your productivity and take advantage of the flexibility offered by Linux, so it’s good we are trying to learn programming BASH script. PCplus using Slackware Linux distro, but this tutorial can be applied to all Linux distributions for use BASH version 4.2 and above. You can use any text editor because basically BASH script is plain text file. You can also try it on a Windows platform with the help of Cygwin,
open the editor:
1. The first step in creating a shell script is telling the system what shell you want to use, because it could be available in a Linux distribution over the shell variant. Because we want to use bash, then write this line in the first row of each bash shell script that will be created
This code is called the shebang and a special instruction that will determine what the interpreter is going to be used to process a shell script. For example, for a script that utilizes Perl interpreter, it will contain information
2. Because the shell script is basically able to execute commands on the shell, then we can run shell commands from a shell script. For example, we want to display today’s date along with the name that we use username to login. Use the code on the listing-1 as an example. Before you can run the script, give it execute permissions on the file with the command chmod + x’s listing 1.sh (adjust the file name you gave) then run the command.
Date command displays the current date information while whoami will menapilkan your user information to login.
3. What if we want to display the text coupled with a shell command? Use the echo function to display a message to the screen shown in listing-2. Echo function accepts parameters in the form of a text message that will be displayed kelayar. You might ask, why the date and user information are on different lines with text displayed? This is due essentially echo function will display a message and then change the next line. To be able to display an information to the right of the text is displayed, use the-n parameter on the function like echo in the listing-3.
4. You can try some of the commands contained in the location / bin and / usr / bin. If not sure of the usefulness of a command, run the command man <nama-perintah> on the console or terminal, for example, man ls and manual information about the ls command will be displayed. Each command has a variation of different parameters with each other, so there are times when we have to read the manual to know every option available.
Jakarta – Indonesia invites the travelers Google using Google Maps on your phone. Rudy Ramawy, Country Head of Google Indonesia, said Google Maps on your phone makes it easy to plan the travelers a safe and comfortable journey.
“Some of it’s ease of search as the most convenient path to the destination,” said Rudy. “You can also find important information regarding the need for travel. Example, the nearest gas station or ATM.”
The travelers can also record all findings during the course of the digital device. “So, when I travel the same route, you can easily find the places you’ve visited,” Rudy explained.
When stuck in traffic, Google Maps users can find an alternative way. This online map applications presents several alternative options that can help road users avoid severe congestion at homecoming.
Google Maps to apply different color lines for different traffic conditions. For example, if there is a congested line, the red line. Yellow to crowded conditions and solid edging, while green for road conditions smoothly.
In addition, Google Maps provides information on the long journey from the user’s location to the destination or hometown. Google Maps even provide mileage information is based on the means of transportation used. For example, driving alone, walking, or using public transportation. Google Maps also provides information public transport fares.
With features and conveniences that exist, Rudy wish Google Maps users can be helped in planning trips back and forth.

Like the models in the fashion world, most outstanding ultrabook now prioritizes slimness of the body and a pretty view. However, these physical characteristics will result in a collision or vulnerable laptop face hostile weather conditions. That try to overcome this shortcoming by presenting a Lenovo T430 repeated his version into the ThinkPad series T430u.
Well, now ultrabook models (ThinkPad T430u) comes with the typical specifications of mobile devices are lightweight and power-saving. Examine the “u” as a marker ultrabook segment here. Series that we try (type 3351-7DA) contains an Intel Core i5-3317U 1.7 GHz, 4GB of main memory, and a 500GB hard disk. Also added a 4GB SSD for ultrabook-style get fast booting.
As general character ultrabook, the Lenovo ThinkPad T430u only include a little plug. This device only provides two USB 3.0 ports, LAN, HDMI, and DisplayPort. This device also has a wireless card slot that can be used to access the internet via a 3G connection. The slot itself is at the back of the laptop is sailing 14 ˝. The bottom of the laptop is also surprisingly easy to open with a special slot (no screwdriver) making it easier for you to upgrade components.
T430u also comes standard Thinkpad features such as finger print reader and an Anti-Theft technology from Intel. However, the laptop weighs 1.9 kg making it a lure is physical endurance-tested to military standards. This test requires the Lenovo ThinkPad T430u resistant to shock, dust, extreme temperatures, up to a humid environment. This is why this Ultrabook casing made slightly thicker (2.2 cm) with glass fiber plastic material to reinforce the cover.
To beautify the inside, Lenovo makes keyboad in design they call the Island-style that stood out. To give the impression of a minimalist, physical buttons for volume settings, wireless, and such removed. Instead, the available combination on the keyboard. Continue to be included on this keyboard also typical ThinkPad trackpoint. With lithiumpolymer 4220mAh battery, the laptop can be used for seven hours continuously.
Given its performance, the Lenovo ThinkPad T430u ultrabook par with most other equivalent. However, it seems to make a strong design-based Windows 8 Pro laptop is becoming prominent. This product is perfect for fans looking for a ThinkPad ultrabook or resilient.
Jakarta-ultrabook exorbitant price makes it less attractive thin notebook. Despite having a number of advantages compared to notebooks in general, such as fast boot time and lightweight body, the average price is above USD 10 million to be a serious obstacle.
As an alternative, some computer vendors began marketing sense ultrabook notebook with a more affordable price. Call it VivoBook X202E Asus, Lenovo IdeaPad Yoga 11, Dell XPS 12, or Acer Aspire V5-122.
Yes, with many excellent features adopted from the ultrabook, notebook sold in the under $ 10 million. But in terms of performance is less than the true ultrabook. But the experience of computing an ultrabook can still be felt on the notebook.
In the past week, Tempo had tried Acer Aspire V5-122. Body is lightweight and thin making the Aspire V5 easily incorporated into the bag and convenient to carry anywhere. Interestingly, in the Aspire V5-122 grafted Temash low-power AMD processors.
Thin, lightweight, and stylish. That first impression when touched obtained Tempo Acer Aspire V5-122. Body wrapped in metallic silver color adds an elegant notebook with a 11.6-inch wide screen. While at the bottom, cover plastic dark black plated.
Every corner of the Aspire V5-122 made rounded. While the keyboard on the inside of the black chiclet design. Fairly wide spacing between the keys making it comfortable to use for fast typing.
Touch pad size is not too big, but it’s not a problem. Therefore, Aspire V5-122 is equipped with a touch screen that is able to respond to ten touch points. The touch screen was optimal when used with the Windows 8 operating system from Microsoft.
Like ultrabook, Aspire V5-122 also brought the concept of unibodi. That is, the types of Li-ion battery 3-cell it carries can not be removed. But you do not need to worry because Acer ensure the battery life is long enough.
Like most new output notebooks, Aspire V5-122 is equipped with the latest features for connectivity. One of which is USB 3.0 is capable of transferring and receiving data 10 times faster than USB 2.0. USB 3.0 port is located on the left side.
In addition to USB 3.0, Aspire V5-122 is equipped with a USB 2.0 port is on the right side. In addition there is a card reader slot. As for the wireless connectivity, Acer presents Wi-Fi 802.11 b / g / n and Bluetooth 4.0.
Screen Aspire V5-122 is able to produce high levels of brightness. Using glossy reflective technology, the Aspire V5-122 black color makes it look more dense and the resulting image sharpness deeper than the regular screen.
Only, with a relatively cheap price than the ultrabook, Acer just immerse the display with a standard resolution, 1,366 x 768 pixels only. That is, watch the video with 1080p high definition resolution was less than optimal on-screen Aspire V5-122’s.
Moreover, with the use of the Windows 8 operating system and the increasing number of applications that require content HD screen resolution, screen technology Aspire V5-122 feels a little left behind.
Acer Aspire V5-122 is equipped with AMD processors Jaguar Temash APU A6-1450 quad-core processors with speeds up to 1 GHz of computing processes. As for the graphics processing embedded AMD Radeon HD 8280G which has a thermal design power (TDP), only 8 watts.
Jaguar AMD A6-1450 APU processor is the new output. This low-power processor platform is the successor of Zacate and Ontario, the first generation processor which is equipped with power-saving features with four cores.
Low power consumption that makes the battery life to be quite long. During the trial, Tempo get the battery can last up to 5 hours with normal use and use the Wi-Fi connectivity.
To support the performance of the processor, Acer relies DDR 3 RAM memory of 6 GB with a storage capacity of 500 GB hard-disk. Hard-disk usage is what makes the Aspire V5-122 can not be called as an ultrabook, but of course the use processors made by AMD.
Pegged at a relatively affordable price, about Rp 5.5 million, Acer Aspire V5-122 can be regarded as a substitute for the ultrabook much cheaper price. Elegant design and weighs only 1.3 pounds, this slim notebook comfortable to carry around.
As a colleague, Aspire V5-122 can be relied upon, especially he amplified output low-power processors AMD. In the market, the Aspire V5-122 directly compete with VivoBook S200E Asus, Lenovo IdeaPad Yoga 11, Lenovo ThinkPad Edge E130 and Sony Vaio SVE 1111.

So what’s the secret to this panel can be very thin? The secret lies in between the display panel and touch the film (layer touch screen). LG Dual Flexible Printed circuit inserts instead of regular single circuit. All components are then combined with Optical Clear Resin parts in between the panel and touch the film with immediate unification system. As a result, it will automatically reduce the thickness of the panel itself as much as 30 percent.
With the presence Optical Clear Resin, this new tech screen brightness can have a better screen. With a full HD screen resolution of 1920 × 1080 pixels and it has a maximum level of 535 nits brightness, the LCD screen of LG’s latest look more perfect and claimed to still be clearly visible even under the conditions used in the scorching sun.
Unfortunately, LG has not announced when the LCD screen will make her debut for smartphones and tablet PCs. Most likely we will see it the first time in LG branded products.
