Linux Mint, like Ubuntu and most other Debian-based distros, do not enable the root account by default. If you need root permissions to do something, enter the command

sudo [whatever program you want to run]

and enter your password when prompted.

What is the command used to change the file access permission?

Linux
  • chmod: change permission bits (only the owner and root are allowed to do this)
  • chown: change owner and group (only root is allowed to change owner, group may be changed by owner)

Do Unix commands work in Linux?

The ones that are listed as part of a standard (such as Posix) will work in all UNIX systems (but not all systems, such as Windows command prompt).

A lot of UNIX vendors add commands that only work in their version of UNIX, so they aren't as portable across systems as others.

What is the directory in Linux?

One of the most noticable differences between Linux and Windows is the directory structure. Not only is the format different, but the logic of where to find things is different

In Windows, you use this format to access a directory:

C:\Folder1\subfolder\file.txt

In Linux, this is the basic format:

/Folder1/subfolder/file.txt

You'll notice that the slashes are forward slashes in Linux versus backslashes in Windows. Also, there is no drive name (C:, D:, etc.) in Linux. At boot, the 'root partition' is mounted at /. All files, folders, devices and drives are mounted under /. Though it is not apparent from this example, it is important to note that files and folders in Linux are case sensitive. /Folder1/subfolder/file.txt is not the same as /folder1/subfolder/file.txt.

What are file permissions in Linux?

The typical way to view file permissions is to use the 'ls' command with the long listing options enabled, For example, to see the file permissions for everything in the current directory, type:

ls -lsa

What is root in Linux?

Will switching to Linux require a company to purchase new computers?

No, but hardware cards in some computers may not already have drivers (firmware) to interface with the Linux kernel. It is less expensive to replace one card than to develope a new driver.

Purchasing new computers with Linux preinstalled may also provide better tech support agreements than having a local tech run a custom installation on each model.

Where are applications installed in Linux Mint by default?

The most common places would be in: /bin (system utilities) or /usr/bin (usually user programs).

Some applications like Steam will install the game library in your user's home folder (by default) instead of doing it Windows-style which would be in the Program Files directory.

What is the role of the free software foundation in the development of Linux?

On a technical level? Nothing directly. In fact, as time went on it seemed like Richard Stallman seems to really dislike Linux.

Some claim that Linux wouldn't exist without GNU, which was RMS' doing, but in all honesty Linux could still have easily existed without it. It's nnot like GCC was the only C compiler in existence in 1991.

What are the disadvantages of SUSE Linux?

While SuSE has made a great effort to develop a wonderful configuration tool like Yast, in no way does SuSE restrict or limit the the user to 'have' to use it.

There are plenty of confiuration tools that you can use to fiddle with SuSE and all of them work just fine.

Scp can be harmful but some are friendly and they would like to play with you. Not all scps are nice some are dangerous. I think the worst one is scp 049 because he kills you and you become a copy of him and he is your king when he kills you.

How do you recover a deleted file in Linux?

That depends on the file system and the environment used. When you delete something from the console, it is intended to be permanent, although depending on the file system, you may still be able to retrieve it. In a desktop environment, files are moved to a folder akin to the recycle Bin in Windows, and can be retrieved at any time until permananently deleted.

How do you locate lines beginning and ending with a dot using grep and sed commad?

grep can match the beginning of a line with the '^' character and the end of a line with the '$' character. Any character is matched by the '.' character, so to match a literal "." you will need to use the escaped '\.' sequence. Thus to match a line beginning with a dot and ending with a dot you would use:

grep '^\..*\.$'

This will match any line that both begins with a dot and ends with a dot, and has any characters in between.
