Linux

TOSS is TCE Operating System Services, a Linux distribution forked from Ubuntu and developed entirely by students of Thiagarajar College of Engineering,India.

Its website is http://toss.tce.edu

Much better, safer, and faster than Windows.

semaphore.h is in the kernel source. If you're looking for it for your particular distribution (such as for compiling modules), look in the kernel source package or install the kernel headers.

lpstat -t

A signal is a command sent by the operating system or by the user, to a program or process, forcing it to do something.

The "kill signal" forces a program to immediately "close" (terminate) regardless of what it is doing.

You should not use the "kill signal" unless the program has a problem or cannot end or close properly, because you will lose whatever it is working on.

Yes. Valve has released the Linux version of Steam, and there is a steadily-increasing number of games in Steam that are playable in Linux (and some of them are cross-platform, like Portal, Team Fortress, Left 4 Dead, etc). As an alternative, Valve also released SteamOS (which is based on Linux).

rpm -q pkge_name

mand will query the specifid package if it is already existing,otherwise it will give message that package is
not installed.

Yes. Google offers both 32-bit and 64-bit binaries for Linux on Google Earth's download page.

ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key

ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

for the DSA and RSA host keys, respectively (it will also create a corresponding .pub file). You can of course specify another filename and then move/copy them in place.

Assuming you're using SSH to log into the server itself?

You'll need to generate a keypair and give the server the private key. There are tons of tutorials for this. Google it.

• To change the current directory to /etc/java/bin, use the command "cd /etc/java/bin".
• To add the above path to the PATH variable, type export PATH="$PATH:/etc/java/bin".
• To check whether you have successfully added that PATH, type "echo $PATH".
• To permanently add /etc/java/bin to PATH variable, edit /etc/profile or ~/.bashrc file and add the command, export PATH="$PATH:/etc/java/bin". (NOTE: After adding, you will need to reboot the machine or type "source /etc/profile" or "source ~/.bashrc".

An absolute pathname, is the location of a filesystem object relative to the root directory.

absolute pathnames always begin with a slash (/).

With Absolute pathname you have access to complete file system objects such as directories and files.

Distributions generally try to maintain binary compatibility, so a binary compiled on, say, Ubuntu, should run fine on Fedora, as long as all necessary libraries are installed. Any free and open-source application can be adapted to any modern distro, so even if a distro doesn't maintain binary compatibility, they can still run the same applications. They just need to be compiled separately.

Linux command "dump" backup 0 means to store everything or full backup.

Linus Torvalds uses Fedora.


He did an interview in 2008 where he talked about distributions. He uses Fedora on most of his computers, but really doesn't focus on the distribution itself.

Here's the link to an article on O'Reilly where the interview is referenced:

Yes, the Tixati BitTorrent client is a good and safe client.

It runs on both Linux and Windows.

KDE and GNOME are the result of two different attempts to create a free and open-source desktop environment for Linux. KDE was created first. KDE used a widget toolkit known as "Qt", which was not open-source back then. Since some users wanted one that was completely open-source, even the toolkit, the GNOME project was created. Many users still liked KDE, though. Those who did not want to switch stuck with KDE. Those who insisted on free software chose GNOME. Later, the Qt toolkit was open-sourced, which removed much of the incentive for GNOME to exist, but enough users at that point like GNOME better, so development has continued.

Microsoft does not develop Visual Studio for Linux - the closest available thing is MonoDevelop. It looks and acts similar to VS, and can be found in most distribution repositories

In a terminal, type "ps aux | grep [insert name of mail server]". If you see more than one process listed, the server is running. Otherwise, it is not.

There is nothing particularly unique about this notebook; any modern Linux distribution should be able to run on it without problems.

Read-only

The major advantage of a hash table is its speed. Because the hash function is to take a range of key values and transform them into index values in such a way that the key values are distributed randomly across all the indices of a hash table.

The output would be 'shell shell' (without the quotes, of course)

#Touch newfile Will make an empty newfile

Red Hat Linux was discontinued in 2004 in favour of Red Hat Enterprise Linux for enterprise environments. However, Red Hat Linux still exists as "Fedora", free for home use, developed by "Fedora Projects", though the entire line is no longer commercial and only supported by the Linux community.
