Bash Scripting - Conditionals
You have a variable score. Write an if-elif-else block that prints "Fail" if score is below 50, "Pass" if score is between 50 and 75 inclusive, and "Excellent" if above 75. Which script is correct?
Aif [ $score -lt 50 ]; then echo "Fail" elif [ $score -le 75 ]; then echo "Pass" else echo "Excellent" fi
Bif [ $score -le 50 ]; then echo "Fail" elif [ $score -lt 75 ]; then echo "Pass" else echo "Excellent" fi
Cif [ $score -lt 50 ]; then echo "Fail" elif [ $score -lt 75 ]; then echo "Pass" else echo "Excellent" fi
Dif [ $score -le 50 ]; then echo "Fail" elif [ $score -le 75 ]; then echo "Pass" else echo "Excellent" fi
Step-by-Step Solution
Solution:
Step 1: Fail condition
Score below 50 means less than 50 (-lt 50).
Step 2: Pass condition
Between 50 and 75 inclusive means score greater or equal 50 and less or equal 75. Since fail covers below 50, just check less or equal 75 (-le 75).
Step 3: Else is Excellent
Scores above 75.
Final Answer:
if [ $score -lt 50 ]; then echo "Fail" elif [ $score -le 75 ]; then echo "Pass" else echo "Excellent" fi -> Option A
