Bash Variable Here’s our birthday cake price script in Bash: #!/bin/bash birthdaycake=2 birthdaycake =$(( birthdaycake / 2 )) echo The price of a birthday cake is $ birthdaycake When we run this code, we get the following result: The price of a birthday cake is 1 The = operator assigns a value to the variable. The $ operator before the variable name references the value stored in that variable. The double parenthesis (( )) tells Bash we are performing a calculation example divide birthdaycake/2 Bash Array dates=(1,2,5,16,23,25,28) date [0] The date[0] would give us the value of 1 from our array above. #!/bin/bash dates=(1,2,5,16,23,25,28) echo 'The third day offering a discount is: ' ${dates[2]} The script will produce the following output: The third day offering a discount is 5 When referencing an array in Bash we use the {} curly braces. Note: Bash uses zero-indexing which means when counting elements in an array, you start with 0. Therefore when dates[2] this would be the 3rd position in the array; as 1 would be in position 0, 2 would be in position 1, and 5 would be in position 2 (where our script points).
