What is an operator?

Operator is an symbol in programming that performsn an operation on operands

Syntax

```
operand1 operator operand2
```

There are two types of operators.

- Binary Operator: It operates on two operands such as addition, subtraction, multiplication, division, and modulus
- unary operator: It operats on single operand such as increment and decrement

## Bash Arithmetic Operators

Arithmetic operators in Bash provide arithmetic operations such as add, division, subtraction, and division multiplication operators.

Operator | Title | Description | Example |
---|---|---|---|

+ | Addition | addition of two or more operands | p+q=50 |

- | Subtraction | subtraction of two or more operands | q-p=10 |

* | Multiplication | multiplication of two or more operands | p*q=600 |

/ | Divide | results quotient after the division of values | q/p=1.5 |

% | Modulus | Return the remainder after the division of values | q%p=10 |

% | Modulus | Return the remainder after the division of values | q%p=10 |

-expr | Unary Minus | reverse of an expression | -(10-7) is -3 |

~/ | Division Int | returns division int value | (10~/7) is 1 |

++ | Increment | Increment the value by 1 | ++p=21 |

-- | Decrement | Decrement the value by 1 | --q=29 |

&& | Addition | addition of two or more operands | p+q=50 |

Subtraction |

## Assignment Operators

## Bitwise Operators

Operation | Symbol | Description | Result |
---|---|---|---|

AND | `&` | Bitwise AND of two operands | $op1 & $op2 is 0 |

AND Equal | `&=` | Bitwise AND Equal of two operands | $op1 & $op2 is 0 |

OR | `|` | Bitwise OR of two operands | `$op1 | $op2 is 7` |

XOR | `^` | Bitwise XOR of two operands | $op1 ^ $op2 is 7 |

Left Shift | `<<` | Bitwise Left Shift of two operands | $op1 & $op2 is 0 |

Left Shift Eql | `<<=` | Bitwise Left Shift Equal of two operands | `$op1| $op2 is 7` |

XOR | `^` | Bitwise XOR of two operands | $op1 ^ $op2 is 7 |

XOR | `^=` | Bitwise XOR Equal of two operands | $op1 ^ $op2 is 7 |
