The command line interpreter in Linux is known as the shell. When a user runs a command, the shell interprets, processes, and executes the command and provides an output to the user. Linux comes with quite a few shells such as Bourne

What is BASH?

The Bourne Again Shell (BASH) is a command language interpreter for the GNU's Not Unix (GNU) operating system. The following files are used to configure BASH:

The inode table contains the last access time, last modification time as well as the last inode change time of a file.

What type of data is stored in an inode table?

An inode table contains a list of all files in an ext2 and ext3 filesystem. An inode ( index node) is an entry in the table, containing information about a file (the metadata). Some important data stored in the inode table are as follows:

The file type (regular file, directory, etc.)

File permissions

Link count: The number of file names associated with the inode number.

The user ID number of file owner and the group ID number of the associated group.

Timestamps, including last access time, last modification time, and last inode change time.

Location of the data on the hard disk.

aspell is a utility that can function as an ispell -a replacement, as an independent spell checker, as a test utility to test out Aspell features, and as a utility for managing dictionaries.

Syntax:

aspell [options]

Some important options used with aspell are as follows:

The following options may be used with the aspell command to control which dictionaries to use and how they behave:

Answer option A is incorrect. The tee command is used to split the output of a program so that it can be seen on the display and also be saved in a file. It can also be used to capture intermediate output before the data is altered by another command or program. The tee command reads standard input, then writes its content to standard output, and simultaneously copies it into the specified file(s) or variables.

The syntax of the tee command is as follows: tee [-a] [-i] [File] where, the -a option appends the output to the end of File instead of writing over it and the -i option is used to ignore interrupts.

Answer option B is incorrect. The concatenate (cat) command is used to display or print the contents of a file.

Syntax:

cat filename

For example, the following command will display the contents of the /var/log/dmesg file:

cat /var/log/dmesg

Note: The more command is used in conjunction with the cat command to prevent scrolling of the screen while displaying the contents of a file.

Answer option D is incorrect. There is no such utility as dict in Linux.
