Linux GUI utilities are time-consuming and awkward to use. You can run a simple Linux command to do the equivalent task in a fraction of the time. Here’s how to use Linux command “patterns” to run Linux commands.

Linux GUI utilities provide an easy “point-and-click” method of doing Linux administration tasks, but they are time-consuming and awkward to use. You can run a simple Linux command to do the equivalent task in a fraction of the time it would take to use a Linux GUI utility.

When you get Linux training, be sure that it is focused on how to use Linux commands. Also, if you are interested in getting Linux certification, you need to know how to use Linux commands to be able to pass, not Linux GUI utilities.

Linux Tips - How to Use Linux “Patterns” (Linux Wildcard characters)

Some Linux documentation uses the term “pattern” to refer to Linux wildcard characters.

Wildcard characters are used in a “pattern” to cause a Linux command to work on multiple items, such as multiple directories and files in the Linux file system.

The two Linux wildcard characters are the * (asterisk) and ? (question mark).

Using an * (asterisk) with a Linux Command

An * (asterisk) is used in a pattern to represent “all” characters of an item (directory or file).

The Linux command below shows an example of the using the cp (copy) command to copy all (because of the * without any other letters or numbers) files in the current directory into the directory named memos.

]# cp * memos

Linux Tips: Keep in mind that Linux commands are “case sensitive”. Always type the letters in upper or lower case, as shown.

Linux Tips: Also, be sure to use spaces where they are shown. For example, in the Linux command above, you need a space (just a single space) between cp and the * and you need a single space between the * and memos.

The * (Linux wildcard character) can be combined with one or more letters at the front of it or after it.

The following Linux command is an example of the using the cp (copy) command to copy all files in the current directory beginning with the letter r into the directory named memos.

]# cp r* reports

The Linux command below copies all files ending in “sxw” into the directory named weekly.

]# cp *.sxw weekly

The next Linux command copies all files containing “mem” (anywhere in the file name) into the directory named monthly.

]# cp *mem* monthly

Using a ? (question mark) with a Linux Command

The ? (question mark) is used in a pattern to represent a single character.

The Linux command below shows an example of the using the mv (move) command to move files that have a single character and end in “cfg” into the directory named june.

]# mv ?.cfg june

The following Linux command moves all files beginning with “month”, and having two characters after “month”, and ending in “sxw”, into the folder named years.

]# mv month??.sxw years

To learn how to use Linux commands the easy way, you can watch Linux video tutorials. When you work with Linux videos, you can actually see Linux commands being run and hear a detailed description of why you need to run a certain Linux command.

Another benefit is that you can also see the output of the Linux command and hear a description of what the output means.

After seeing how to use Linux commands, you can run them yourself - to get practical Linux training.

First of all, a web design company should always have a portfolio website. Any companies that does not is probably new in the field but even then they should have their own website along with some special websites they built entirely for their portfolio. Avoid firms that don’t have portfolios because you have no way of knowing their ability otherwise.

Their portfolio examples should comply with currently accepted web design standards. What are the currently accepted standards? They can be found on the website for the World Wide Web Consortium or W3C for short (http://www.w3.org/). The information on the W3C site might seem overwhelming but there is a simple way to quickly check a website and that is by using their validation service found at http://validator.w3.org/. This tool is easy to use and only requires input of the site URL listed in the portfolio.

Do you like the overall style of their web design portfolio? That style will be the same style they apply to your website. If you do not like the way they combine colours, display text, and lay out their pages then you should shop for a web designer with a style that will fit you.

When evaluating how fast one of these websites loads, it is important to discern if it is designed in Flash or designed in HTML. A Flash website will load everything first and then display while a HTML site will render as it reads instructions sequentially. Consequently, HTML websites should always load faster. You can usually tell a Flash website by the progress indicator that displays while it is loading. HTML pages should load quickly if you have a normal internet connection. However if you see the text display quickly and then the images paint slowly then it is an indication that the web designer does not know how to optimize website objects such as photographs.

Saving some files could be such great problems for many of us who need to work with such gigantic file capacity. When we need to transfer a big file to the other computer, we would need to use the external hard drive to do that. That would be such a very unpractical thing to be done. Thanks to the development of the computing technology that finally invented the massive storage for the giant files, the blue-ray dvds.

This is certainly the ultimate way to store some big files. You simply don’t need to break down a file into some smaller files and scarifying its quality, because the blue-ray dvds could save some giant files in a single disc. With its up to 500 giga bytes capacity in the multiple layers, it has a very special ability to store some giant files into a single disc.

How does it work? Well, the blue-ray dvds use the blue-violet lasers technology. With the shorter wave length than the red laser, those lasers allow some precise imprinting and also give more space available in the disc. With the up to 500 giga bytes information that could be stored in the disc, this is surely a big help for some people who need to work with the giant file capacity.
