How can you specify a text pattern that must be at the beginning of a line of text using a regular expression?
- A.
Precede the string with a /.
- B.
Follow the string with a \.
- C.
Precede the string with a $.
- D.

Correct Answer
D. Precede the string with a ^.Explanation
To specify a text pattern that must be at the beginning of a line of text using a regular expression, you need to precede the string with a ^. The caret symbol (^) is a special character in regular expressions that represents the start of a line. By placing it before the string, you are indicating that the pattern should match only if it appears at the beginning of a line.Rate this question:

Linux has only one root directory per directory tree. True or False?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Linux does indeed have only one root directory per directory tree. This means that there is a single top-level directory from which all other directories and files branch out. This root directory is denoted by a forward slash ("/") in Linux systems. Having only one root directory helps to maintain a hierarchical structure and organization within the file system.Rate this question:

Using wildcard metacharacters, how can you indicate a character that is NOT an a or b or c or d?
- A.
[^abcd]
- B.
Not [a-d]
- C.
[!a-d]
- D.
!a-d
Correct Answer
C. [!a-d]Explanation
The correct answer is [!a-d]. This is because the caret (^) symbol inside the square brackets indicates negation, meaning that any character that is not an a, b, c, or d will match. The other options, [a-d], [^abcd], and !a-d, do not correctly represent the desired condition of not matching any of the specified characters.Rate this question:

A user typed in the command pwd and saw the output: /home/jim/sales/pending. How could that user navigate to the /home/jim directory?
- A.
Cd ..
- B.
Cd /jim
- C.
Cd ../..
- D.
Cd ./.
Correct Answer
C. Cd ../..Explanation
The user can navigate to the /home/jim directory by using the command "cd ..". This command moves the user up one level in the directory structure, so by using it twice, the user will be in the /home/jim directory. The other options provided in the question are incorrect. "cd /jim" would try to navigate to a directory called "jim" directly under the root directory, "cd .." would only move the user up one level in the current directory, and "cd ./." would stay in the current directory.Rate this question:
