Asked in Linux, Unix, The Difference Between
What is the difference between Linux and Unix?
To put it very generically, Linux is an operating system kernel, and UNIX is a certification for operating systems. The UNIX standard evolved from the original Unix system developed at Bell Labs. After Unix System V, it ceased to be developed as a single operating system, and was instead developed by various competing companies, such as Solaris (from Sun Microsystems), AIX (from IBM), HP-UX (from Hewlett-Packard), and IRIX (from Silicon Graphics). UNIX is a specification for baseline interoperability between these systems, even though...
Asked in Microsoft Windows, Linux
How do you dual-boot Windows and Linux?
Install Windows first, if you have not installed either yet. After it is installed, just install Linux to the other partition or disk. Most modern Linux distributions use GRUB, which will detect and automatically configure a menu for you to choose from when you start the computer. ...

What is the best operating system and why?
Note: Both Mac OS X and Windows have come out with newer versions as of the writing of this answer. Some details may be different from what is written below, and the answer should be updated accordingly. The best desktop operating system to use depends on what its intended use will be and who will be using it. There is no specific operating system which can be called "the best" overall, and since most current operating systems share most common and advanced features...
What are the differences between Windows and Linux?
That is a question that has many different answers, depending on what aspect of Windows or Linux you want to know about. Both are what are known as Operating Systems, and in this case, both are designed to work on the same type of hardware -- PCs, otherwise known as IBM Compatibles. There are enormous differences in the way that they behave at a technical level, but I suspect what you really want to know is how they differ from the...
Asked in Lincoln LS, Business Law, Linux, Incorporation
What does LS after signature mean?
L.S. is the abbreviation for the Latinism "locus sigilli", meaning the place reserved for the signatory's unique seal. Most U.S. states have abolished the need for a seal to authenticate the signature. Older documents can be found with a wax wafer melted onto the L.S., impressed with a corporate, government, or private insignia (the seal), perhaps with color-coded ribbons or strings also embedded in the wax under the seal. ...

What is udev in Linux?
Udev is an important device management system primarily used by the kernel and the userspace to more readily detect, manage, and populate your hardware to the system. When you first boot a Linux system, the bootscripts found in the initramfs will use udev to dynamically detect and load drivers for all your hardware and populate /dev with virtual device files. While it is possible to run a Linux system without udev, it is not recommended and is usually only done in mobile...
What do you mean by file permission -rw-rwx-wx?
There are 10 characters in a string for a Unix-style file permission. The format is: dooogggaaa (where d is a directory flag, o indicates the permissions for the file owner, g indicates the group the file belongs to, and a is for everyone else [all]) The permission values breakdown: d is only available on the first character, and if toggled, this means that the file is a directory (folder). - means no permission (or in the case of the first character, it means it's a file...
Asked in Computers, Linux, Unix
What does chmod 654 stand for?
chmod is a utility that allows you to change the file permissions. The octal value 654 equals to -rw-r-x-r-- (or drw-r-x-r-- if it's a directory). This means that the file owner can read and write to the file (but not execute), users in the file's group can read and execute (but not write), while for everyone else it's read-only. Explanation The "read" permission is assigned the value of 4 The "write" permission is assigned the value of 2 The "execute (program)" permission is assigned...
Asked in Microsoft Windows, Linux
When pack command is used the original file size is reduced by?
There is no "pack" command in Linux. However, there are numerous compression and archival programs available for use. "tar" is an archival program. It does no compression, but allows you to put multiple files into one. "gzip" is a compression program. However, it can only compress one file. Used in conjunction with tar, it is just slightly better than the ".zip" format. "bzip2" is another compression program with better compression ratios. Like "gzip," it is for compressing single files only. It is usually used...
Define the purpose for writing shell scripts as a superuser?
I presume you mean writing shell scripts that operate under the super user account - scripts are written for any reason to help automate tasks and make them much less error prone than issuing commands as a user. Running as the superuser merely means that the commands in the shell script require superuser priviledge to execute. ...

How do you identify text and binary file in Linux?
You can distinguish between binary and text files, and for the most part even identify what type of binary file, by using the "file" command. For example: ~$ file unknownfile unknownfile: PNG image data, 155 x 155, 8-bit/color RGBA, non-interlaced This tells you that the file is a PNG file by reading metadata and/or magic numbers in the file. When used on a text file, the command will return "ASCII text" or "Unicode text." ...

How do you compile software on Linux?
Most programs you can download in source form can be compiled using the following simple steps: 1. Extract the source package (ex. 'tar xzvf programname-version.tar.gz'), this will create directory programname-version. Chdir into it. 2. Run './configure'. This checks the build environment to make sure your compiler works and has the proper libraries installed. 3. Run 'make'. This compiles the program. 4. Run 'make install'. This places the binaries in the appropriate location(s). 5. Depends on GCC version also ...
Asked in Linux
When should you specify an ext2 file system instead of ext4?
ext4 supports a feature called 'journalling' which prevents filesystem corruption in the event of a power failure or system crash. When you are certain you don't need it, you can choose ext2. But for the vast majority of users, ext4 is the best option. ...

Can you run Microsoft applications on Linux?
Yes and no. Linux will not run Windows applications by itself, however, there are ample tools written for Linux that permit you to run Windows applications on Linux. The open-source WINE software will run a majority of Windows software on Linux. You can even configure Linux to automatically recognize Windows applications and use WINE to run them. Alternatively, there's a wide variety of virtual machine products that permit you to run the Windows operating system as an application under Linux, and, in...

How do you connect Microsoft IIS Oracle 9iAS and MySQL to three computers when two of them are using Linux and the other one Win XP?
I want to wish you the best of luck. I would start off Number one by haveing a really good network admin. If your an Admin then you have some work. Number one Microsoft IIS, Oracle 9iAS, and the SQL server should all be stand-alones. You would have to link computers together with atleast a 10-Base-T hub. Call network something and make all Gateways, ISPs for these "servers". You would also need to have the "Servers" auto-handshake ISPs from other computers. HAve...

What is the best Linux distro?
As Linux can be tailored to suit different needs, many contradictory, there is no single distro that is perfectly adapted to all of them. And "best" is a matter of opinion; some may think one looks better than another; some may want more features while others want better performance on lower-end hardware. ...
How can you tell whether a given file is a directory and how can you list all files in a directory including subfolders?
== == In a programming context, one usually determines whether a file is a directory using functions that access file metadata. These are dependent on the system you are programming and what language you are programming in. You should consult a reliable reference for the programming language, such as the manpages for C and C++ (in Unix-like systems) or Java's Javadocs (available on the web). To list all files in a directory, a programmer will usually iterate across all members of the directory...

What is the Linux version of System32?
