Question 1
Which of the following commands is used to capture both the standard output and standard error of a script and redirect them to a file named log. txt?
./script. sh > log. txt
./script. sh 2> log. txt
./script. sh &> log. txt
./script. sh | log. txt
./script. sh >> log. txt
Correct Answer: Option 3
Correct Answer Explanation: The &> operator is a shortcut in Bash that redirects both file descriptor 1 (stdout) and file descriptor 2 (stderr) to the specified file.
Wrong Answers Explanation:
Option 1: This only redirects stdout. Errors will still appear on the screen.
Option 2: This only redirects stderr. Regular output will still appear on the screen.
Option 4: The pipe symbol is used to send output to another command, not a file.
Option 5: This appends stdout to a file but does not capture stderr.
Question 2
How do you check the exit status of the most recently executed command in a shell script?
echo $ST
echo $?
echo $#
echo $!
echo $@
Correct Answer: Option 2
Correct Answer Explanation: The special variable $? stores the exit status of the last command. A value of 0 usually indicates success, while any non-zero value indicates an error.
Wrong Answers Explanation:
Option 1: $ST is not a standard pre-defined shell variable.
Option 3: $# represents the number of arguments passed to the script.
Option 4: $! stores the process ID of the last background command.
Option 5: $@ represents all the command-line arguments passed to the script.
Question 3
What is the purpose of the 'shebang' line (#!/bin/bash) at the start of a script?
To define the script version
To provide administrative permissions
To specify the interpreter used to execute the script
To encrypt the script content
To hide the script from other users
Correct Answer: Option 3
Correct Answer Explanation: The shebang tells the operating system which program to use as the interpreter (in this case, Bash) to execute the instructions contained in the file.
Wrong Answers Explanation:
Option 1: Versioning is usually handled via comments or metadata, not the shebang.
Option 2: Permissions are handled by the 'chmod' command, not the script header.
Option 4: The shebang is plain text and offers no encryption capabilities.
Option 5: It is visible to anyone who can read the file; it does not provide security or obfuscation.

Who Should Take This Course
"DevOps Shell Scripting - Practice Questions 2026" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
