Converting from a decimal to hexadecimal number is even easier.And because this statement is true, piping it to bc will give us an output of 1. Using the bc command with the echo command to perform boolean operationsĪs you can see in the screenshot above, we passed to echo the statement that “1 is less than 2”. We can achieve this by, once again, utilizing the echo command with pipes. Continuing down the mathematical scripting language application of the bc command, we can also perform boolean operations where 1 is true and 0 is false.This is important to do for this specific operation as you are liable to receive an error otherwise. Because of this, we can also utilize the bc command to determine mathematical variables in the Linux command line terminal.ĭetermining variables using the bc command and the echo commandĪs you can see in the syntax above, we surrounded the variables following the echo command in quotation marks. As mentioned earlier, bc is also used as a mathematical scripting language.Using the echo command and piping the output to the bc command to do calculations without entering the interactive shell This will echo any text we type and pass it to the bc command. For this process, we’ll need to utilize the echo command and | pipes. But we can also perform mathematical operations in the Linux terminal using bc without entering the interactive shell.You can achieve this by using the Ctrl + D key combination or typing quit. This pattern will continue until you exit the interactive mathematical shell. Using the bc command to calculate 2×2 and 4/2Īs you can see in the screenshot above, pressing enter upon typing out a mathematical operation, bc will calculate the equation directly below. And for the multiplication operation, we’ll need to use the * asterisk instead. For division, we’ll simply use a / forward slash between two numbers. We can also do multiplication and division.We can do simple addition by typing a + sign between two numbers.Using the bc command by itself to enter the interactive mathematical shell to do basic calculations. And the second way that bc works is as a mathematical scripting language, but that will be covered later.

Once we’re in, we can start executing some basic mathematical operations. We can enter the shell by simply running the bc command by itself. The first is through entering an interactive mathematical shell. There are two main ways in which the bc command works.$ – requires given linux commands to be executed as a regular non-privileged user # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command Privileged access to your Linux system as root or via the sudo command.

In this tutorial, you’ll learn how to use the bc command in Linux through examples. The calculator can also handle variables and algebra, or do other useful things like convert numbers to hexadecimal. If you’re familiar with the C programming language, you’ll probably notice that the syntax for the bc is quite similar. But it’s also possible to use the bc command in Linux to run calculations through the command line terminal. Most users naturally think of a calculator on their computer as a GUI application, or something that is accessed directly from the desktop.
