Bash Shell Scripting - Arithmetic Comparison Operators

The video tutorial covers arithmetic comparisons in shell scripting, focusing on operators like less than, greater than, equal to, and not equal to. It explains the use of variables and conditional statements, highlighting the differences between square brackets and parentheses. The tutorial demonstrates testing comparisons with symbols, addresses syntax errors, and explores advanced operators such as GE, LE, EQ, and NE. It concludes with best practices for using these operators effectively.

Which of the following is NOT an arithmetic comparison operator discussed in the video?

• Addition

• Greater than

• Less than

• Not equal to

What is the correct way to use a variable in a conditional statement with square brackets?

• Using the variable with a hash sign

• Using the variable with a dollar sign

• Using the variable with an ampersand

• Using the variable name directly

What is one advantage of using parentheses over square brackets in conditional statements?

• Parentheses are faster to execute

• Parentheses require more code

• Parentheses allow the use of symbols directly

• Parentheses are more visually appealing

In the context of the video, what is the benefit of not using dollar signs with variables in parentheses?

• It makes the code easier to read and comprehend

• It reduces the chance of syntax errors

• It increases the execution speed

• It makes the code more secure

Which operator is used to check if a value is greater than or equal to another value?

• LE

• EQ

• GE

• NE

What does the 'NE' operator stand for in shell scripting?

• Not equal

• Next element

• New entry

• Not empty

Which operator would you use to check if two values are equal in shell scripting?

• EQ

• NE

• GT

• LT
