Perl Operator Types

Perl supports many types of operators. The table shows all the operator types in the Perl language.

Arithmetic - These operators mirror those you learned in grade school. Addition, Subtraction, and Multiplication are the bread and butter of most mathematical statements.

Assignment - These operators are used to assign a value to a variable. Algebra uses assignment operators. For example, in the statement X = 6, the equal sign is the assignment operator.

Binding - These operators are used during strong comparisons.

Bitwise - These operators affect the individual bits that make up a value. Each character binary notation represents a bit, which the smallest piece of a computememory that you can modify.

Comma - The comma operator has two functions. it serves to separate array or list elements and it serves to separate expressions.

File Test - These operators are used to test for various conditions associated with files. You car test for file existence, file type, and free access rights among other things.

List - List operators are funny things in Perl. They resemble function calls in other languages.

Logical - These operators implement Boolean or true/ false logic.

Numeric Relational - These operators allow you to test the Relational relationship of one numeric variable to another.

Postfix - A member of this group of opera-tors-(), [], {} appears at the end of the affected objects.

Range - The range operator is used to create a range of elements in arrays. It can also be used in a scalar context.

Reference - The reference operators are used to manipulate variables.

String - The string concatenation operator is used to join two strings together. The string repetition operator is used to repeat a string.

String Relational - These operators allow you to test the relationship of one string variable to another.

Ternary - The ternary operator is used to choose between two choices based on a given condition.
