A file attribute is metadata that describes or is associated with a computer file. For example, an operating system often keeps track of the date a file was created and last modified, as well as the file's size and extension (and what application to open it with). File permissions are also kept track of. The user may attach other attributes themselves, such as comments or color labels, as in Apple Computer's Mac OS X (version 10.3 or later).

2. CTRL + H

if there are less clear, write your comments below. thank :)

need to know! 
In computing, a hidden directory or hidden file on a computer is a directory (folder) or file which a user cannot see by default. Hidden directories most often serve to hide important operating system-related files and user preferences. However, malicious programs can also use this functionality to hide their presence from unaware users.

In MS-DOS and other DOS systems, users can make files and folders hidden or visible by toggling their Hidden File attribute using attrib command. Invoking dir /a may reveal the existence of unsuspected hidden objects.

In addition to the "dotfile" behaviour, files with the "Invisible" attribute are hidden in Finder in Mac OS X. This is set using the SetFile command. For example, invoking SetFile -a V jimbo will hide the file "jimbo". Alternate way is to use chflags command. chflags nohidden ~/Library/ clears hidden attribute on user's Library folder on Mac OS X 10.7 while SetFile fails with an error.

Turn Off AutoRun

AutoRun is a technique used to automatically run a process. AutoRun runs when there is a storage device detected. and this technique is usually utilized by the virus. therefore we also have to be careful with the AutoRun. AutoRun is turned off only if necessary. how to turn it off ? follow the following ways.

1. open run (CTRL + R).
2. typing "gpedit.msc".
3. entry Computer Configuration -> Administrative Templates -> System
4. open feature Turn Off Auto Play.
5. Select Enabled -> All Drive.
6. entry User Configuration -> Administrative Templates -> System
7. open feature Turn Off Auto Play.
8. Select Enabled -> All Drive. 

 if there are less obvious post a comment below. thank :)

need to know! 
AutoRun and the companion feature AutoPlay are components of the Microsoft Windows operating system that dictate what actions the system takes when a drive is mounted.

AutoRun was introduced in Windows 95 to ease application installation for non-technical users and reduce the cost of software support calls. When an appropriately configured CD-ROM is inserted into a CD-ROM drive, Windows detects the arrival and checks the contents for a special file containing a set of instructions. For a commercial application, these instructions normally initiate installation of the software from the CD-ROM. To maximise the likelihood of installation success, AutoRun also acts when the drive is accessed ("double-clicked") in Windows Explorer (or "My Computer").

Until the introduction of Windows XP, the terms AutoRun and AutoPlay were used interchangeably, developers often using the former term and end users the latter. This tendency is reflected in Windows Policy settings named AutoPlay that change Windows Registry entries named AutoRun, and in the autorun.inf file which causes "AutoPlay" to be added to drives’ context menus. The terminology was of little importance until the arrival of Windows XP and its addition of a new feature to assist users in selecting appropriate actions when new media and devices were detected. This new feature was called AutoPlay and a differentiation between the two terms was created.

need to know! 
In computing, a command is a directive to a computer program acting as an interpreter of some kind, in order to perform a specific task. Most commonly a command is a directive to some kind of command line interface, such as a shell.


Specifically, the term command is used in imperative computer languages. These languages are called this, because statements in these languages are usually written in a manner similar to the imperative mood used in many natural languages. If one views a statement in an imperative language as being like a sentence in a natural language, then a command is generally like a verb in such a language.


Many programs allow specially formatted arguments, known as flags, which modify the default behaviour of the command, while further arguments describe what the command acts on. Comparing to a natural language: the flags are adverbs, whilst the other arguments are objects.

Change Login Background In Linux

login view on ubuntu is often called by GDM. in other words we will change the background of GDM. Essentially we will change the login background to use the software in linux that is Appearance. but Appearance is usually only used in desktop. to be in use also when we login, we must add Appearance at startup login. follow these steps.

1. open terminal - typing "sudo su" - insert your root password.
2. copy Appearance by typing "cp '/usr/share/applications/gnome-appearance-properties.desktop' '/usr/share/gdm/autostart/LoginWindow'"
3. then logout your computer.
4. at login would appear like the picture above.
5. selections click close.

login background has been changed. follow these steps to eliminate the Appearance window at login.

1. open terminal
2. typing "sudo rm '/usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop'".
3. insert your root password.

Asked if there is please leave a message on this post. thank you for your attention :)

need to know! 
GDM is the abbreviation of the GNOME display manager. Ubuntu uses the GNOME desktop. so in ubuntu using the GDM login screennya. whereas on linux kubuntu using KDM (the KDE display manager) because kubuntu uses KDE desktop. There are also new in version 11.10 ubuntu (oneiric ocelot). oneiric GDM does not use anymore because it has been replaced with LightDM which has a more elegant look.

Install File Type .Bin

usually if the windows installer (executable) files which we know only file type .Exe . but in linux we will find some installer files. examples such as file type bin, deb, tar.gz, tar.gz, sh, and other.

but this time I specifically discuss the file type bin. following way.

1. open terminal
2. change directory to folder containing the bin file. by typing "cd path". example : cd /home/husnu/packet tracer
3. typing "./file_name.bin". example : ./PacketTracer53_i386_installer-deb.binPacketTracer53_i386_installer-deb.bin.
4. wait until the installation is complete
   

sorry if things go wrong. thank :)

need to know!
In computing, an executable file causes a computer "to perform indicated tasks according to encoded instructions," as opposed to a data file that must be parsed by a program to be meaningful. These instructions are traditionally machine code instructions for a physical CPU. However, in a more general sense, a file containing instructions (such as bytecode) for a software interpreter may also be considered executable; even a scripting language source file may therefore be considered executable in this sense. The exact interpretation depends upon the use; while the term often refers only to machine code files, in the context of protection against computer viruses all files which cause potentially hazardous instruction execution, including scripts, are conveniently lumped together.
