bc

The bc command in Linux is a simple calculator that can be used to perform basic and complex mathematical operations. It is a powerful command that can be used to perform any calculation that can be expressed in the C programming language.

The bc command is used in the following syntax:

bc [options] [expression]

The expression is the mathematical expression that you want to evaluate.

The options can be used to specify the following:

• -l : Use the long format for output.

• -q : Quiet mode.

• -s : Set the scale.

For example, to evaluate the expression 2 + 2, you would run the following command:

bc

This command will evaluate the expression and print the result, which is 4.

To use the long format for output, you would run the following command:

bc -l

This command will evaluate the expression and print the result in the long format, which is 2 + 2 = 4.

To use quiet mode, you would run the following command:

bc -q

This command will evaluate the expression and print no output.

To set the scale to 2, you would run the following command:

bc -s 2

This command will set the scale to 2, which means that all floating-point numbers will be rounded to two decimal places.
