Linux passwords are not stored in plain text, but in a scrambled or encrypted form known as a hash. A hash is a one-way function that transforms a string of characters into a fixed-length value. The same input always produces the same hash, but it is impossible to reverse the process and recover the original input from the hash. This way, the system can verify the user's password without exposing it to anyone who can read the file where the hashes are stored. The file that contains the password hashes is /etc/shadow, which is only readable by the root user or members of the shadow group. The passwd utility is used to change the user's password, which updates the hash in the /etc/shadow file.Reference:Linux Essentials 1.6 Topic 105: Security and File Permissions,How to Change Account Passwords on Linux,Where is my password stored on Linux?

The command pwd stands for ''print working directory''. It will print the absolute path of the current working directory to the terminal.For example, if we are currently in the /home/user/directory, it will print out that exact path1.The pwd command is useful for finding out where we are in the file system hierarchy and for verifying the location of files and directories2.

The other options are not commands that show the absolute path to the current working directory.The who command shows the users who are currently logged in to the system3.The cd ... command changes the current working directory to the parent directory of the current one2.The ls -l command lists the files and directories in the current working directory in a long format, which shows the permissions, ownership, size, date, and name of each file and directory2.The cd ~/home command changes the current working directory to the /home directory under the user's home directory, which may or may not exist2.Reference:

The correct command to create an archive file work.tar from the contents of the directory ./work/ is tar --cf work.tar ./work/. This command uses the -c option to create a new archive, the -f option to specify the file name, and the ./work/ argument to indicate the source directory. The other commands are incorrect for various reasons:

A . tar --new work.tar ./work/ is incorrect because there is no --new option in the tar command. The correct option for creating a new archive is --create or -c.

C . tar --create work.tgz --content ./work/ is incorrect because the -content option is not valid. The correct option for specifying the source files or directories is --files-from or -T. Also, the work.tgz file name implies compression, but the command does not use any compression option such as -z, -j, or -J.

D . tar work.tar < ./work/ is incorrect because the tar command does not accept input redirection from the standard input. The correct way to use the tar command is to provide the options and arguments after the command name.

E . tar work > work.tar is incorrect because the tar command does not produce output redirection to the standard output. The correct way to use the tar command is to use the -f option to specify the output file name.Reference: :tar command in Linux with examples - GeeksforGeeks:tar Command in Linux With Examples | phoenixNAP KB

The backslash character () is used to escape the meaning of the next character in a command line. This means that the next character is treated as a literal character, not as a special character. For example, if you want to use a space in a file name, you can use a backslash before the space to prevent the shell from interpreting it as a separator. Similarly, if you want to split a long command line across multiple lines, you can use a backslash at the end of each line to tell the shell that the command is not finished yet. The shell will ignore the newline character and continue reading the next line as part of the same command. For example, you can write:

ls -l

/home/user/Documents

instead of:

ls -l /home/user/Documents

Both commands will produce the same output, but the first one is easier to read and type.Reference:

The correct command to extract the contents of the compressed archive file1.tar.gz istar -xzf file1.tar.gz. This command uses the following options:

-xmeans extract files from an archive.

-zmeans filter the archive through gzip, which is a compression program that reduces the size of files.

-fmeans use the following archive file name, which is file1.tar.gz in this case.

The other commands are incorrect for the following reasons:

tar -czf file1.tar.gzcreates a compressed archive file1.tar.gz from the files specified after the command, not extract it.

ztar file1.tar.gzis not a valid command, as ztar is not a standard program or option for tar.

tar --extract file1.tar.gzis missing the-zoption to handle the gzip compression, and also the-foption to specify the file name.

detar file1.tar.gzis not a valid command, as detar is not a standard program or option for tar.
