Linux

I am running Tux Paint on Ubuntu 9.04 Jaunty Jackalope. Tux paint did not ask where to save the image. I could find the saved image in ~/.tuxpaint/saved

The GNU project develops programs and utilities for an as yet rudimentary operating system known as "GNU." Since the programs are open-source, they have been adapted to work using the Linux kernel as well. Other than using its programs, there is no direct relationship.

In Linux, command typed at a command prompt displays a list of commands that would likely contain the command you desire. For example, to find all of the commands that have word flush in their name or descriptions type the following: man -k flush

You can get a list of all the files in the current directory with the "ls -a" command.

In Windows, files have an owner (usually the creator), but not a group, to which they 'belong'. - and the owner isn't really important in determining access rights. Files either have an explicit list of people and groups or inherit it from a parent directory. These lists specify individual users and groups (in a list) who have access to the directory/file/subdirectories, and the specific rights granted to each item.

In Unix/Linux, each file and directory belongs to a specific user AND group - for example, configuration files may belong to user root and a group set up for administrators (typically called 'wheel'). Instead of having a list of people who can/cannot access the file, you simply specify read, write and execute privileges for the owner and group the file belongs to, and then anyone else.

In Windows, if you have a configuration file, the owner doesn't matter. Instead you set the ACL to include any Administrators you want to access the file, as well as any other users that may need to read it, including the program it configures.

In Linux, you'd perhaps set the same configuration file to belong to the root user, and the group to which the configured program runs in, and everyone to no rights at all - so only root and the program can read it. Or you could set the owner to the user the program runs under and the group that the Administrators belong to, so the program can read it and so that Administrators et.al. can change the file, but keep everyone set to no rights to keep the configuration secure.

They are two different ways of accomplishing security, each with their own configuration peculiarities and performance issues.

There is no "default" shell. Different distros are free to pick whatever shell they want. The most commonly used as the main shell is Bash, but other shells, including the Korn shell, C shell, Friendly Interactive Shell, or Almquist shell are also available. Many distros also use a variant of the Almquist shell provided by BusyBox in their initial ramdisks before switching to the real root and launching the main shell.

* Most Linux operators are more familiar with the inner workings of their systems than most Windows users, so they are usually more capable of setting up their machines securely.

* Many Windows "features" require execute and other priviledges on the machine. This means that, by default, Windows security is set up to be looser. These priviledges can be taken advantage of by people with malicious intentions against users that have not made adequate security adjustements on their machines.

* Most "hackers" want to get the most bang for their effort. Since Windows is used on far more computers than Linux, they focus their efforts on creating hacks or viruses that effect Windows systems.

The man command of the Linux operating system is the system's documentation pager. Each page argument given to man is normally the name of a program, utility or function. For example, to see the reference manual of the grep program: man grep

syntax:

ls -aF

-a option is for hidden files

-F is for directories and executable files

The answer seems to be "no" - I bought the Lexmark version of this cartridge, and it doesn't work - the chip on it causes the printer to read "invalid cartridge". Some older versions used an additional slot to differentiate between Dell and Lexmark, but they've now gone down the hardware route and there doesn't seem to be a way around it.

That means you have to order from Dell, and I need to print today. $50 from Office Depot down the drain and no other option. I'm selling this POS printer and buying one from a company that doesn't so blatantly screw its customers.

The password of the 7zip file archive deoends on the actiual owner of the file. Still if you want to unlock 7zip file password then go for eSoftTools 7z Password Unlocker Tool. It can can restore any type of pasword with any length including non-English and English characters Get full information here: https://www.esofttools.com/7z-password-recovery.html

ls (ie lower case LS)

In DOS: dir

If there are many files in the directory, type, "dir/p/o" ...this will stop the listing when the page fills up and list them in alphabetical order... press any key to continue to the next page of listed files.

If you're only interested in the name of the files (not the date/size etc.) you can add /B

The Linux superuser is called "root." There is very little root cannot do. This is why it is a Very Bad Idea to do anything as root unless absolutely necessary. Use sudo instead with commands that need it.

The swirl used as Debian's logo refers to "magical smoke." When you blow up a computer, the "magical smoke" is released, and the computer no longer works. Debian is meant to be part of the magical smoke that makes your computer work.

None. Swap is to be put on the hard disk.

Do NOT mistake secondary storage for "physical RAM." Physical RAM is actually the term used in context of the actual system memory in your computer.

Also, Linux 2.4 is an ancient codebase, obsolete kernel version that isn't even supported by kernel.org anymore. You should be using 2.6.32.61 or later.

Finally, the rule of thumb is 1.5 times the amount of physical RAM. So, if I have 4 GiB of system memory, then I'll make a 6 GiB swap partition.

Generally the default behavior of the 'ls' command will list them in alpha order.

There is no one "current Linux operating system" due to the fact that Linux is developed and distributed in various forms by many different individuals and corporations. The current version of Linux depends on which of these "distributions" you are interested in installing.

For example, a popular distribution of Linux tailored for use as a Desktop system is Ubuntu (www.ubuntu.com), which is distributed by the company Canonical. The current release of Ubuntu is 8.04, which was released in April this year.

There are literally hundreds of distributions freely available online, but other distributions which are of note in the desktop arena include Fedora (www.fedoraproject.org), openSUSE (www.opensuse.org) and Debian (www.debian.org), each of which have their own advantages and disadvantages. Each distribution has its own release schedule, but you can find out what the current version is (and download it) from the official websites.

No. Windows is pretty much the only operating system that cares about primary vs. logical partitions when it comes to booting. Linux will happily live in logical partitions.

That being said, with UEFI becoming that standard, logical vs. primary partitions aren't even going to be concepts anymore, as the GPT scheme doesn't limit partition counts the same way as MBR, allowing hundreds of primary partitions, way more than even highly specialized applications would ever need.

No, none of the passwords used in a Linux system can be "recovered" because there isn't a reverse encryption for it.

However, you can "reset" the root password by using the single-user mode at boot time (which puts you in the root account automatically) and then changing at that time.

Nobody. Code is contributed by and remains the property of the many volunteers and employees of various companies.
