What are the most important features of Linux os?
In no particular order
It is under GPL, an open-source license that protects the authors from commercial abuse of their code by others. Much of the traditional Linux software stack is written with this in mind, which deeply affects the software politics involved in Linux
It works with the most software and on the most hardware. It can run on anything from a smartwatch to a supercomputer. Indeed many supercomputers use Linux.
It is free. Not just free to use and download, but free to learn from, improve upon and code for. The source is open for all to review; as such you can see how complex programs are built, often easily since the most popular projects are well documented, owing to the contributor nature of GPL and opensource.
Why we have passwd and shadow files?
The passwd file is public and readable by anyone. For this reason you do not want to have some sensitive information placed there, such as the user's password. Passwords and password aging rules are stored in the shadow file that is only accessible by the root administrator account. This way information that is displayed by commands such as 'finger' can use public information but sensitive information such as the password of a user is not accessible.
How much does it cost to download the avg Linux?
The AVG Linux Server Edition 2012 is free of charge to download from the official AVG website. If you want to test it first, there is also a free trial download available.
What are the PS and pstree commands in Linux?
PS (see "man 1 PS") in Linux is a program that generally comes with the operating system that allows you to see information about the running processes.
pstree is a program that lets you see the processes as a tree, to see which process started which other process, for example.
Where can you download .deb files for Linux?
.deb (Debian Package) files are primarily found in the distro's repository. You generally should not deal with them directly, but rather through your package manager, such as apt, Synaptic, or Adept. You can also browse the repository online to download individual .deb files individually.
Why do Linux care about upper and lowercase in file names?
It isn't so much that Linux cares about them as much as it supports them. The command line tools in Windows are modeled after MS-DOS, and thus cannot distinguish between upper- and lowercase letters. You cannot have two files that have the same name, but different capitalizations for this reason in Windows.
Linux, however, recognizes the differences between upper- and lowercase letters. There are times when you might want to have different capitalizations but otherwise identical filenames. So file.txt, File.txt, and FILE.TXT are all considered separate file names.
Where is the program files folder located in openSUSE?
Application binaries in Linux distributions (including openSUSE) are stored in several directories, depending on their purpose or method of installation. These are:
/sbin
/bin
/usr/bin
/usr/sbin
/usr/local/bin
Is there any way to get a functional driver for an Nvidia GeForce FX 5200 for PowerPC on Debian?
The only 3D accelerated (what I assume you mean by "functional") drivers for NVIDIA cards for Linux are for x86 and x86-64 computers. The only support for Nvidia cards elsewhere would be the nv driver (which is already included), and only supports 2D acceleration.
What is the make command in Linux?
The make(1) command is a utility program which was originally developed for Unix in 1977. The make command is a rule-driven program that executes a sequence of commands to create or update one or more files, based on a graph of prerequisite file relationships described in the rules and the modification times of the prerequisite files.
Make is most commonly used for compiling programs or libraries from source files, but it can be used for things other than software development.
What is used to resolve a hostname to an IP address?
DNS Server (Domain Name System) resolves Hostnames to IP Addresses in Internet.
HOSTS file in Windows computers is responsible for resolution of hostnames to ip addresses.
A daemon is the equivalent of a "service" in Windows. It is a program that runs in the background and performs tasks without any need for interaction, such as a web server or a program to automatically sync to the correct time.
Can you run Linux on Palm Lifedrive?
Yes you can. However Its still in the early stages so there's no sound or WiFi yet.
How does Linux differ from traditional software?
Linux differs from traditional operating system primarily in the fact that most distributions are available free of cost.
What are the different memory management techniques used by Linux operating system?
There are many diffferent memory management techniques used in any Operating System, and Linux is no different. The answer is not simple and is beyond the scope of this type of question. I would refer you to any of the Linux kernel books for more in-depth discussion of the techniques that are used.
Which commands list your outstanding print jobs?
lpc status shows a list of the print queues
lpq shows what is in the default print queue
lpq -Psomeprinter shows what is in a specific print queue
Chances are that you are not printing outstanding material at any given time. If you are using CUPS, you might not have the lpr compatible utilities installed (cups-bsd package in debian based installations).
What is a package manager in Linux?
A package manager is a utility to install remove, upgrade, and track the dependencies of software in Linux.
What is the current versions operating systems for Linux?
You need to include the names of the Operating Systems if you want a answer, because there are hundreds of different Linux variations.
In which directory are stored the icons of Linux Mint?
The icons of Linux Mint are located in the folder /usr/share/icons/Mint-X
You can use that path, e.g., to change the icon of the desktop launchers, like this:
+ Right click on the desktop launcher icon.
+ Click on "Properties".
+ Click on the icon.
+ Paste on the Place box the text /usr/share/icons/Mint-X/ and press Enter.
+ Navigate the folders to find the icon you like.
+ Press Enter.
+ Click on Close.
In /usr/share/icons there are more icons, most of them inside other folders: gnome, ...
What kind of interface does the old Linux operating system use?
How much old do you mean by old?
Well, before Gnome and KDE, there was the Command Line Interface (CLI).
MCC Interim Linux was the first linux distribution, released in February 1992 used the CLI.
Where is the terminal in Puppy Linux Dingo?
The terminal is called rxvt, It's in /usr/bin/rxvt, You can open it by clicking the "Console" icon on the desktop. Woof!
GRUB is the bootloader for Linux operating systems. The bootloader is the section of code on the hard disk drive that is called and executed at bootup. It will load the operating system components and programs and start the operating system.
Which runlevel only grants root access?
In traditional System V init systems, that'd be runlevel 1 or "single user mode." This should only be used in emergencies where normal boot is not working at all.
As Linux is generally going over to systemd, the idea of a "runlevel" is going away, and instead systemd will try to hit specific "targets" during boot. You can change the run target to something like single user mode, but only if necessary.
