Question

Quizplus · Accepted Answer

In Bash scripts, variables can be created by assigning a value to a name. The most common way of doing this is by using the format "variable_name=value". Therefore, the correct syntax for creating a variable named firstname with a value of "John" in a Bash script is "firstname="John"". Option A is incorrect because the "let" keyword is not necessary in Bash for assigning variables. Options C and D are incorrect because Bash doesn't have a data type declaration keyword such as "string" or "str".
