Скачать или смотреть Lab 05: Bash Loop Tutorial (While & For) | Sum, Even-Odd Check, Factorial & Practical Tasks

In this Operating System Lab 05, we learn how to use Loops in Bash Shell Scripting with practical examples.

This lecture covers both while loop and for loop with different syntax styles. We also solve real lab-based problems like calculating sum, checking even/odd numbers, printing even numbers in a range, and calculating factorial using loops.

Topics Covered in this Lecture:

While Loop in Bash
For Loop (Range style and C-style syntax)
Sum of numbers using loop
Check whether sum is Even or Odd
Taking multiple user inputs using loop
Print even numbers from 1 to N
Factorial calculation using loop
Lab-based practical scripting examples

This video is helpful for beginners, CSE students, and OS Lab practical preparation.


After completing this lecture, students will be able to:

Understand the concept of looping in Bash.
Implement while loop and for loop correctly.
Use C-style for loop syntax in shell scripting.
Perform arithmetic operations inside loops.
Take multiple user inputs dynamically.
Apply conditional statements inside loops.
Solve real lab problems like sum, even-odd check, and factorial.
Develop logical thinking for scripting tasks.
