• In this exercise, you will create a script called if_then_elif.sh that uses an IF THEN ELIF statement and various integer operators
• The if_then_elif.sh script will
• Use one command line argument, which will be a number between 1 and 10
• Assign the value of the first argument to a local variable called NUM. HINT: Look at line 5 in the example screenshot for arguments.sh
• Use one IF THEN ELIF statement to compare NUM
• If the value of NUM is less than 4, display the message "The number is less than 4"
• If the value of NUM is between 4 and 7, display the message "The number is between 4 and 7"
• If the number is greater than 7, display the message "The number is greater than 7"
• Here are some hints
• Watching the video about IF THEN ELSE/ELIF Statement may be helpful
• The IF THEN ELIF statement has the form

If [ $NUM operator number ]

then

echo ""

elif [ $NUM operator number ]

echo ""

else

echo ""

fi

• There must be a space after each element to avoid syntax error messages; i.e. there must be a space after the bracket, $NUM, operator and number
• Decide which integer operator to use for each comparison. Look at the slide "Integer Operators"
• Decide what the value of number should be for each comparison
• Decide which message should go where
