• The if_then_else.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 ELSE statement to compare the value of NUM
• If the number is less than 5, display the message "The number is less than 5"
• If the number is 5 or greater, display the message "The number is 5 or greater"
• When running
• Here are some hints
